Tips to help keep operating costs down

Find lower fuel costs with five timely tips

Fuel is a necessity and a major expense item for construction companies. As prices spike, so does the possibility that your profitability might take a hit, but there are ways to help lower your fuel bill and operating costs.

Reduce your idle time

Idling is necessary in certain situations, such as warming up a machine and before shutting down at the end of the day. It could also be justified when you are in high-production activities that involve near-constant movement, such as loading trucks with an excavator and charging crushers with a loader, where restarting would negatively affect productivity.

Telematics helps fleet managers easily track idle time by machine and for their entire equipment lineup. If they see excessive idling, they can then address that with operators and other on-site personnel.

An easy way to help control idle time during unproductive periods is to use the auto idle shutdown function, a feature available on most Tier 4 Final machines. Your machines’ operations and maintenance manuals can guide you on how to set it—the minimum is five minutes before the shutdown begins in most cases—and your local dealer can help, too.

Heed Eco Guidance and choose the right mode

Komatsu’s ECO Guidance provides information to operators on energy-saving operations that help control fuel consumption. It is a feature on most Komatsu machines introduced during the past 10 years. Idling stop guidance is among the suggestions that may be available with ECO Guidance. With this option, typically if no operation is performed for more than five minutes and the engine is idling, the idling stop message is displayed on the monitor.

ECO Guidance is most useful when you choose the most effective mode. ECO Guidance might also suggest operating in “economy” instead of “power” mode.

The “economy” mode promotes enhanced fuel efficiency but maintains working equipment speed for light-duty work, similar to the “power” mode
Excavators and dozers are mainly used to dig and move naturally compacted soils, and in most instances, “economy” mode will get the job done while controlling fuel burn
The “power” mode is advantageous in heavy-duty applications, such as when a wheel loader must climb a 10% ramp with a full bucket or when an excavator moves hard material like heavy clay

Consider a hybrid

Another thing to consider is purchasing or renting a hybrid excavator, such as the Komatsu HB365LC-3. Hybrid excavator technology is designed to provide a fast and responsive swing, and when swinging, to have all available hydraulic power sent to the boom, arm and bucket to help improve cycle time and enhance production.

Properly size and match equipment for the task

Bigger is not always better, and using a large machine to do a job that a smaller one could do can increase fuel usage and your overall operating costs. Fleet managers need to consider several factors when using equipment, including choosing the right size for the job.

An important component of rightsizing is matching equipment that will be working together in the same application. For example, loading and hauling equipment need to match in order to drive optimum efficiency. If a loader is too large for a truck, or vice versa, the project will likely not be as efficient.

Use advanced technology

GPS-based grading helps promote productivity and control per-yard costs to move material. During the past two decades, GPS technology has advanced significantly, with integrated machine control helping to drive lower costs associated with replacing cables, masts and additional satellites.

Many of today’s machines with integrated GPS grade control also feature additional technologies, such as Komatsu’s proactive dozing control, that help operators get to grade more efficiently and at lower costs, including better fuel usage. Technology is also helping new operators become proficient at moving dirt faster than ever before.

Reman facility

Extend equipment life at a reduced cost

Komatsu and SRC of Lexington Inc. work together to provide high-quality remanufactured parts

SRC of Lexington Inc. works closely with Komatsu and its dealership network to provide high-quality remanufactured parts that help extend equipment life. The approximately 100,000-square-foot facility in Lexington, Ky., specializes in remanufacturing heavy equipment components for the mining and construction sectors.

Adam Trebolo, Director of Sales and Marketing at SRC of Lexington, detailed the comprehensive processes and technologies that define the facility’s operations.

“Typically, we remanufacture components like engines, transmissions, hydraulic pumps and motors,” Trebolo explained. “We take old, worn-out parts and completely disassemble them. Parts that can be reused are machined back to the original specifications, and new original equipment manufacturer parts are used for those that can’t be salvaged.”

There are many benefits of remanufacturing, including cost savings and promoted sustainability.

“Remanufacturing reduces the total cost of ownership significantly,” Trebolo emphasized. “Replacing an old engine with a remanufactured one is much cheaper than buying a new machine, and it ensures the equipment is ready for another long service life. Remanufacturing also uses significantly less energy than producing new components. We reuse most of the iron, and we recycle what we can’t use, so it’s a more environmentally friendly option.”

The facility’s operations are meticulously organized to ensure quality and efficiency.

“When we receive a core, it’s first inspected and identified,” said Trebolo. “The disassembly process is kept separate from the assembly to maintain cleanliness, and every part undergoes thorough inspection and machining to meet original equipment specifications.”

A cornerstone of SRC of Lexington’s success is its pivotal relationship with Komatsu, which has existed since the facility’s inception.

“This factory used to be a Komatsu plant until the financial crisis in 2009,” Trebolo recounted. “We persuaded SRC to buy the operation, and since then, we’ve been a separate company but still closely aligned with Komatsu. They are our largest customer, but since then, we’ve taken on business from other OEMs, as well as some work directly with mines on other products.”

Investing in technology

SRC of Lexington’s cutting-edge technology contributes significantly to the plant’s capabilities.

“We use advanced techniques like metal buildup for worn surfaces and high-end machining to ensure parts are restored to their original dimensions,” elaborated Trebolo. “Our coordinate measuring machine and 3D printers aid in precision and efficiency.”

Trebolo added, “One thing that really makes us unique is we have our own electronic work instruction system software, Task Forge, which ensures every step in the remanufacturing process is followed meticulously. We’ve developed detailed photo instructions that guide technicians step by step. With over 100,000 steps in our system, we can ensure consistency and quality across all processes.”

The facility’s focus on lean manufacturing and continuous improvement is evident in its collaboration with the University of Kentucky and Toyota.

“We work on eliminating waste and improving efficiency,” stated Trebolo. “For example, we’ve synchronized the assembly process for similar hydraulic pumps, reducing labor and increasing competitiveness in the market.”

Safety, dedicated employees

At SRC of Lexington, safety is paramount.

“We’re really proud of our safety record here,” Trebolo declared. “We’ve gone over 1,600 days without a lost-time accident, and we prioritize safety to ensure everyone goes home the same way they came in.”

Employee ownership is another unique aspect that drives commitment and quality.

“As an employee-owned company, everyone here has a stake in our success,” said Trebolo. “This ownership mentality ensures that our employees are dedicated to producing the highest-quality products.”

With a focus on quality, efficiency and sustainability, SRC of Lexington continues to be a leader in remanufacturing capabilities. Its partnership with Komatsu and investment in advanced technology ensure that it remains at the forefront, delivering high-quality, cost-effective solutions to its customers.

Remanufactured parts and components could help decrease your machinery’s total cost of ownership, promote profitability

Do you want to save money without sacrificing quality and reduce your carbon footprint at the same time? Using remanufactured parts and components could be the answer.

“Fewer raw materials are used in remanufacturing than new parts manufacturing,” said Matt Beinlich, Senior Director, Remanufacturing Business, Komatsu. “According to a paper from the Rochester Institute of Technology titled ‘Capturing Energy and Resources through Remanufacturing,’ the rule of thumb is that 80% of the mass of a component is reused through the remanufacturing process, reducing the need to extract new materials from the earth. Remanufacturing is necessary and good for the industry and the environment because it contributes to sustainability.”

It can also contribute to profitability, Beinlich added.

“Remanufactured components are a much more cost-competitive option compared to new ones because fewer raw materials are required,” Beinlich emphasized. “The quality of genuine Komatsu remanufactured parts and components is better than will-fit items. That’s why we back them with a one-year, unlimited-hours warranty and a quality assurance program of up to 10,000 hours on major components.”

Enhancing availability

Beinlich leads a new team of Komatsu remanufacturing personnel that is committed to increasing customer utilization of reman parts and components. It includes longtime remanufacturing specialists such as Senior Product Manager Goran Zeravica, as well as Remanufacturing General Manager Isamu Hamai, Parts Sales and Marketing Manager Eric Uehara, Reman Procurement Manager Krutarth Desai, Senior Quality Engineer Cody Clark, and Quality Assurance Specialist Bryan Davis.

“When customers buy a Komatsu machine, they expect that those machines will have readily available, reasonably priced, high-quality parts and components necessary to keep them running throughout the machine’s life cycle,” said Zeravica. “Genuine Komatsu remanufactured components can play a significant role in meeting that expectation. Our goals include improving availability and utilization so that our customers have a better total cost of ownership.”

Zeravica added, “To promote our customers’ success with remanufacturing, we have brought a lot of people together from various parts of the Komatsu family including suppliers, our parts depots and distributors. Ordering reman parts and components will be easier too, as we bring that into the digital age by making them available through My Komatsu.”

Komatsu acquires battery company in drive toward electric equipment and reduction of carbon emissions

As construction and mining equipment industries transition to a more electric future, battery technology has become increasingly important. To support this transition, Komatsu recently acquired American Battery Solutions Inc. (ABS), a battery manufacturer headquartered in Detroit, Mich.

The acquisition will enable Komatsu to develop and produce its own battery-powered construction and mining equipment by integrating ABS’ battery technology with Komatsu’s knowledge and network. The first equipment produced with ABS’ battery technology will be used to power mining equipment in North and South America, where there is increasing demand for electrification. In the future, Komatsu will aim to expand the use of batteries in construction equipment and to establish a global supply system.

Komatsu will be positioned to accelerate the development of battery-powered electric vehicles by utilizing ABS’ battery-related technology to further contribute to the electrification of construction and mining equipment in support of pursuing a decarbonized society. Along with other initiatives Komatsu is pursuing with its partners, these efforts will contribute to Komatsu’s management target of a 50% reduction of CO2 emissions from the use of its products by 2030 (compared to 2010 levels), as well as the company’s challenge target of achieving carbon neutrality by 2050.

Leading provider

ABS develops and manufactures a wide variety of heavy-duty and industrial battery packs, using lithium-ion batteries for commercial vehicles, transit buses, and on- and off-road vehicles. The company provides both standard and custom battery systems engineered to be optimized to each customer’s needs. ABS’ technology, combined with advanced product development knowledge and expertise, enables the company to develop and manufacture battery packs designed to deliver superior performance and product life, as well as promote enhanced safety.

ABS will operate as a stand-alone business entity within Komatsu and will continue its growth plans by executing on its current and prospective customer programs in the commercial vehicle segments. The mining and construction opportunities provided through Komatsu will enable ABS to position itself as one of the world’s leading providers of battery systems in both on-highway and off-highway markets. Post acquisition, Komatsu will continue to support ABS’ battery business to further develop the electrification business.

Meaningful conversations, ability to operate equipment stand out at Komatsu’s Quarry Days held at Arizona Proving Grounds

Meaningful conversations, ability to operate equipment stand out at Komatsu’s Quarry Days held at Arizona Proving Grounds

One of the highlights of Komatsu’s Quarry Days is the ability to get in the operator’s seat and put equipment to the test.

“I think it’s a very good thing for Komatsu to do for operators and businesses that are looking for equipment,” said Brad Disrud, an operator with North American Coal at its Coyote Creek Mine in Zap, N.D. “I currently run an older PC2000 that we are looking to replace down the road, and the ability to get in the new one and make a comparison is valuable. It’s quieter, and the productivity is definitely there. The electronic over hydraulic controls is nice.”

The 1,046-horsepower PC2000-11 surface mining excavator was one of more than a dozen Komatsu machines that attendees could operate or see in action at Komatsu’s Quarry Days, an event that took place at Komatsu’s Arizona Proving Grounds. Among the machines was Komatsu’s new GD955-7 motor grader with a standard 18-foot blade.

“You can definitely tell the GD955 is a game-changer,” said Mauricio Vallejos with Titan America. “The palm steering is something completely different. In the long run, I think it’s going to benefit a lot of operators because it will cut down fatigue. Your hands are always on the controls. I think it has several uses — padding, the finishing touches, making sure our dragline shoes sit on the ground and don’t bend, and road maintenance for the haul roads our HD785s run on. It could allow us to do that in fewer passes.”

Popular PC900LC-11

In addition to the PC2000-11 and GD955-7, attendees were able to operate several other Komatsu machines, including a PC900LC-11 excavator; an HB365LC-3 hybrid excavator; WA900-8 and WA475-10 wheel loaders; a D475A-8 surface mining dozer; a D71PXi-24 Intelligent Machine Control (IMC) dozer; and HM400-5, HD785-8 and HD1500-8E0 trucks. A ZT44 drill and an RF-5 reclaim feeder were on display as well. Attendees could also talk with product experts from Montabert and Tramac about breakers and Hensley Industries about its Kprime tooth system. Montabert, Tramac and Hensley are all Komatsu-owned companies.

“We have solutions at Quarry Days that represent every application within a customer’s job site — from stripping, to loading and haulage, to drilling, blasting, breaking, processing, and dozing, it’s all here,” said Joseph Sollitt, Director of Mining Support Equipment, Komatsu. “It gives customers a chance to put the machinery to the test and see firsthand what it can do in a real-world setting. The feedback has been overwhelmingly positive. These types of events are beneficial for the customer, as well as for us to learn more about them and what we can do to improve their operations.”

James Van Remmen with Interstate Earthworks specifically wanted to operate the recently introduced 204,148-pound, 543-horsepower PC900LC-11 excavator that’s designed for heavy construction, demolition, material handling, deep digs, large mass excavation and quarry/mining applications.

“We wanted to compare it to a competitive brand of a similar size,” said Van Remmen. “The speed was very fast for a machine that big.”

With more bucket and lifting capacity, the PC900LC-11 increases productivity up to 40% compared to its predecessor, the PC800LC-8.

“The PC900LC-11 is ideal for those working in applications that involve moving large amounts of material efficiently,” said Casey Zbinden, Product Marketing Manager, Komatsu. “It’s been a popular attraction at Quarry Days because customers see so many potential uses for it. With an optional counterweight removal system, it’s more easily transported.”

Smart solutions

In addition to equipment, Komatsu representatives from its Smart Quarry solutions and My Komatsu teams were available to show customers the advantages of incorporating technology into their operations.

“Smart Quarry is designed to improve and optimize production, which includes site studies and our new Smart Quarry Site,” said Craig McGinnis, Senior Business Solutions Manager, Komatsu. “What’s great about Site is that it’s brand-agnostic, so it can be used with Komatsu and non-Komatsu equipment. It’s plugged into the machine and transmits actionable data that can be used to improve practices and increase productivity.”

McGinnis continued, “For example, we did a case study and identified that a quarry was only putting about 89 tons on a 100-ton truck during loading. We determined that if they added about six more tons that it would equate to more than 13,000 tons per month in added production with the same fuel burn and time. The savings are significant.”

Great conversations

The ability to network with other contractors doing similar work is another advantage of events like Quarry Days, according to Moroni Wardell, who along with his three brothers owns and operates Wardell Brothers Construction in Morgan, Utah. The full-service construction company manages two gravel pits and currently runs several Komatsu loaders and excavators.

“Sharing information is very valuable because it gives us insight into how others are using the equipment and the production they get from it,” said Wardell. “All new iron looks pretty and runs really well — but talk to a customer that has 10,000 or 12,000 hours, and you will see where the results really are. We have been able to network with a lot of other customers that stand behind Komatsu equipment.”

Chad Mikulec, Regional Operations Manager with Permian Basin Materials, said the ability to talk with Komatsu personnel was another positive aspect of Quarry Days.

“The attentiveness of the people out here, wanting to talk to us and hear what we have to say and be actively engaged is very meaningful,” said Mikulec. “It makes me feel good as an end user that they listen to us. Our opinion matters, and what we say is taken into consideration for new products.”

Komatsu’s GHG Alliance members learn about progress toward zero-emissions goals

At a recent event at Komatsu’s Arizona Proving Grounds, the company showcased the progress of its EVX battery-powered haul truck for members of its Greenhouse Gas (GHG) Alliance. Members had the opportunity to directly observe advancements made over the past year related to the performance and sizing of batteries, engage in a discussion on recent progress within the regulatory environment, and learn how Komatsu plans to leverage the company’s trolley system to advance understanding of battery truck performance in a dynamic charging environment. Specifically, members saw the upgraded EVX truck running on battery, static charging of the battery with the truck hooked up to the trolley line via pantograph, and the truck operating on the trolley line — highlighting the battery being charged without having to stop the truck.

Minimizing impact

Komatsu created the GHG Alliance to bring together mining industry leaders that share a goal of delivering zero-emissions equipment solutions. Members have been collaborating to advance Komatsu’s concept of a power agnostic truck — a haulage vehicle that can run on a variety of power sources, including a diesel engine, or battery and hydrogen fuel cells with both static and dynamic charging capabilities. Membership of Komatsu’s GHG Alliance has grown steadily and now includes nearly a dozen companies.

“The past year has been filled with collaborative efforts between alliance members, technology partners and other industry stakeholders dedicated to achieving our common goals of delivering zero-emissions solutions to the mining industry,” said Komatsu’s Pat Singleton, Product Director for Electric Drive Trucks. “Bringing our alliance members together enabled them to experience the substantive continuation of the journey we first shared at MINExpo 2021, as we have advanced our understanding and development of this critical technology.”

Komatsu is committed to minimizing environmental impact through its business. The company has targeted a 50% reduction in CO2 emissions from use of its products and production of its equipment by 2030 (compared to 2010 levels) and set a challenge target of achieving carbon neutrality by 2050.

Komatsu’s PC210LCE electric excavator set to enter pilot program this year

Construction Publications Inc. — Wed, 26 Jul 2023 19:00:57 +0000

Field Testing

Komatsu’s PC210LCE electric excavator set to enter pilot program this year

After making its North American debut at CONEXPO-CON/AGG 2023, Komatsu’s PC210LCE electric excavator is set to enter a test pilot program later this year.

“As we enter this testing phase, we know that there are many questions about this electric machine, and we will be learning alongside our customers to ensure that, ultimately, the excavator can work well for them,” said Andrew Earing, Director of Tracked Products and Technical Service for Komatsu.

Komatsu’s electric excavator development is part of a larger climate goal for the company.

“We have our own corporate goals of working toward carbon neutrality by 2050,” explained Earing. “That may seem like a long time away, but it’s not. We are dedicated to striving to meet those goals along with the goals of a lot of our customers — which happen to be very similar.”

The PC210LCE is in the 20-ton class and is ideal for operating in urban or indoor environments because it has zero emissions and runs more quietly than combustion-engine excavators.

“With the emissions-free product, it opens up a few doors,” noted Earing. “The first is that this machine can work indoors. It’s zero emissions, so you don’t have to worry about adding on a scrubber or monitoring indoor air quality. You can take it indoors, get to work, and not worry about those factors.”

Earing added, “The other big benefit is the operating environment. The additional feedback that we often get is that it’s an extremely quiet excavator, especially when you have the cab door shut. This means a more comfortable experience for our operators, and externally, a quieter job site for ground crews.”

Partnership with Proterra

The PC210LCE is powered by lithium-ion battery technology developed by Proterra that can give it up to eight hours of operating time, depending on the application.

“Proterra’s been in this industry for over 10 years now,” said Earing. “They are known for producing and installing these batteries in 100% electric transit vehicles, primarily buses, and their transit buses can operate 12 to 24 hours a day, seven days a week. These duty cycles meet or exceed what is expected in the construction industry, so we have confidence in the technology. We’re very proud to have them as a partner.”

With the Proterra battery, the PC210LCE provides optimal performance.

“The battery system, coupled with a 123-kilowatt, 165-horsepower electric motor as the power plant, is going to deliver the same levels of performance as a conventional PC210LC-11 excavator,” remarked Earing.

The electric excavator is also compatible with Komatsu’s Smart Construction Retrofit, an affordable guidance kit that gives operators in the field and managers in the office both access to 2D and 3D design and payload data to help drive accuracy, control load volumes, and improve operations.

Construction equipment electrification: a glimpse into the future of the electric job site

Alissa B — Mon, 15 May 2023 20:07:37 +0000

Innovative Technology

Construction equipment electrification: a glimpse into the future of the electric job site

From electric vehicles (EVs) to mining equipment, the shift toward an electric-powered world to reduce carbon emissions — including construction equipment electrification — has already begun.

The Bipartisan Infrastructure Law, which President Joe Biden signed in November of 2021, includes an investment of up to $7.5 billion for EV charging stations to help build out a national network of 500,000 EV chargers.

Additionally, the Bipartisan Infrastructure Law created a joint office between the Departments of Energy and Transportation to collaborate with local communities and provide technical assistance to support the creation and development of EV charging infrastructure.

Actions are being taken at the state level as well. The California Air Resources Board announced the Advanced Clean Cars II rule in August of 2022 that codified Governor Gavin Newsom’s climate goals for the state. The rule established that all new cars and light trucks sold in California must be zero-emission vehicles by 2035.

“While electrification is at the forefront of everyone’s mind due to automotive, our equipment on the construction site is often creating that infrastructure for electric automobiles,” remarked Andrew Earing, Director of Tracked Products and Service at Komatsu. “There are challenges, and we have solutions to those challenges that we are exploring, but it’s not going to be a one-size-fits-all solution for the various applications and the various sizes of the products that we provide.”

The electric advantage

Komatsu recently showcased a PC210LCE electric excavator and a fully electric compact wheel loader prototype at Bauma 2022, an international trade fair that was held in Munich, Germany, as well as CONEXPO-CON/AGG 2023 in Las Vegas.

In a press release, Seiichi Fuchita, Chief Technology Officer and President of the Development Division at Komatsu, noted that for Komatsu to reach its target of reducing the CO2 emissions of products in use by 50% by 2030 (from 2010 levels), and “to achieve carbon neutrality by the end of 2050, we are looking for promising technologies from suppliers to accelerate our electric machine development.”

“Industries including construction are trending in the direction of carbon neutrality,” added Earing. “We want to be a leader. We are a technology leader when it comes to construction and mining equipment. We feel that electrification is one viable option in the construction space.”

With the PC210LCE, Komatsu created an electric excavator from a popular size class.

“We wanted to introduce the 20-ton size class, because it opens us up to a lot of different operating applications and environments,” explained Earing. “They’re going to be used indoors and outdoors. It’s a very diverse size class, and we wanted to get a much better understanding of all those applications and how they work with electrification.”

In 2023, the PC210LCE will begin to see real work on the job site.

“In North America, we are going to conduct a pilot program where we will work with many of our customers to jointly test not only this machine, but the solutions for our customers’ applications to better understand the benefits to them, and how we can help meet their needs,” said Earing.

Meanwhile, a Komatsu electric wheel loader prototype, created in collaboration with Moog, is currently undergoing further tests to enhance and showcase the advantages of a fully electric machine, such as increasing its operating cycle, adding assist functions, and creating a comfortable environment for the operator. The wheel loader also has sensors to add automation capabilities.

Compared to its combustion predecessors, electric machinery provides two immediate advantages: better air quality and noise reduction.

“With a zero-emissions machine, it allows the flexibility for that piece of equipment to operate indoors without harming the air quality around it,” said Earing. “It can now operate in areas where it may not have been able to before and for longer durations. When you have a traditional emissions vehicle operating indoors, air quality has to be monitored, and sometimes the machine must be shut down for extended periods of time to let emissions dissipate.”

Metropolitan and urban worksites are often accompanied with restrictions for when a contractor can work — in part to reduce noise pollution for the populace.

“That’s why urban environments are another application for electric machines,” Earing continued. “It’s not only due to exhaust emissions, but also because of sound emissions. Going with an electrified machine, which has near zero sound emissions, allows for an extended operating window for our contractors and customers.”

Bridging the gap to construction equipment electrification

While combustion engines will remain crucial to the development of electric infrastructure, there is currently hybrid machinery available to help the transition between 100% combustion and 100% construction equipment electrification.

Komatsu released its first hybrid excavator in 2008, and its most recent model, the HB365LC-3, entered the market in 2017.

“The HB365LC-3 offers increased fuel efficiency without sacrificing power. A topper on the cake is the added benefit of reduced emissions that lowers your carbon footprint and promotes sustainability,” said Kurt Moncini, Senior Product Manager at Komatsu. “Based on the Environmental Protection Agency’s CO2 formula, the hybrid potentially offers up to a 20% reduction in CO2 emissions compared to the standard PC360LC-11.”

The force behind the excavator’s fuel savings is its electric swing motor, which offers a glimpse into the capabilities of future electric excavators. The electric swing motor captures and regenerates energy as the upper structure slows down and converts it to electric energy.

Moncini explained, “It’s using energy that would normally be wasted and makes it available to do work, contributing to increased efficiency and decreased diesel usage.”

The energy captured during each swing braking cycle is stored in the HB365LC-3’s ultracapacitor. Each time the excavator swings, the capacitor discharges electric power to the electric swing motor.

“A traditional battery requires time for the chemical process that releases electricity to occur,” stated Moncini. “The heavy work nature of construction equipment places a much faster demand on power transfer. The ultracapacitor’s ability to store and discharge energy quickly makes it ideal.”

He added, “Since swing is fully electric, all available engine power can go to the boom, arm and bucket when bringing a loaded bucket out of the ground and over a truck, spoil pile or hopper. This creates a faster cycle time and a very quick, responsive swing.”

In addition to powering the swing motor, the ultracapacitor sends electric energy to the engine via the motor-generator. This energy is used to accelerate the engine from an ultra-low idle speed of 700 revolutions per minute (rpm) and improve hydraulic response.

It is this technology that can likely be applied to future electric excavator models to extend battery life and increase power.

“Komatsu has the technology to not only capture but also supply energy into an electric swing motor, which gives the HB365LC-3 up to an additional 70 horsepower that it can use for efficiency needs or even use for additional performance needs depending on the customer’s application,” said Earing.

Steps toward carbon neutrality

Complete construction equipment electrification and hybrids are at the forefront of construction’s push toward carbon neutrality, but electrification is just a part of what the industry sees as a solution to meeting carbon goals.

“We’re not just exploring electrification — we’re also exploring other technologies that are out there such as hydrogen fuel cells and clean fuels,” said Earing. “We’re looking at all of these options because we’re making sure that we have the right solution for the right job site and customer application.”

Earing concluded, “In the future, I would say that the trends that we see in carbon neutral machines will depend on the machine application, plus size and weight. With different sizes, there are going to be different technologies that suit those machines.”

Going Green

Takco Construction Inc. improves productivity by incorporating Komatsu HB365LC hybrid excavator into fleet

Takco Construction Inc. was founded in 2010 by Byeong “Ben” Im, who named the vertical construction company after his father, Tak, with “co” standing for construction. Headquartered in LaGrange, Ga., Takco pivoted its focus in 2016 when the firm expanded into two divisions: construction and civil. Vice President Steve Lowery noted that the company has grown tremendously over the last few years.

“We’ve transitioned from renting 100% of our equipment to owning 25-plus pieces of machinery in a short amount of time,” Lowery shared. “With that, we’re taking on larger projects and expanding the territory we service.”

Takco’s operations have expanded nationally across 18 states, with its primary territory covering Alabama, Georgia and Florida. The company employs approximately 75 people, and its workload typically consists of mass grading, storm drain, underground utilities, asphalt, and concrete projects.

HB365LC helps double production

Recently, Takco completed work at the Hyundai seating factory in Hope Hull, Ala. The project involved underground utilities, storm structures, mass grading, lime stabilization, cut and fill excavation, topsoil replacement, pond digging, and base prepping for asphalt. Takco needed an additional machine to meet the project’s deadline, so the company rented a Komatsu HB365LC-3 hybrid excavator.

According to Boswell, the HB365LC was used for various site and underground infrastructure tasks on the Hyundai job site. The electric swing motor, a unique feature of the HB365LC, significantly increased productivity by speeding up the truck-loading process for Takco’s operators.

“We found the HB365LC to be a great, all-around machine,” stated Boswell. “It’s very versatile and could handle tasks like loading off-road dump trucks, grading, digging ponds, laying storm sewer, and utility work without struggling. When loading trucks, the hybrid electric swing motor typically doubled our production.”

The term “hybrid” refers to the combination of a traditional diesel engine with advanced electric technology. In the HB365LC excavator, the electric swing motor captures and regenerates energy during swing braking, which is then used to power the swing motor. This innovative process leads to lower total emissions compared to other excavators in its class.

“We noticed a significant drop in our fuel and DEF consumption shortly after adding the HB365LC,” reported Boswell. “With higher fuel prices these days, the excavator saves the company a significant amount of money and lowers our overhead.”

Boswell particularly appreciated the HB365LC’s responsiveness.

“With a typical excavator, you’ll have a delay until you actually start swinging, especially with a heaping load,” said Boswell. “With the HB365LC, you don’t have that delay. As soon as you hit the joystick, you’re swinging with a good amount of speed. You can strike, turn, strike, turn, and stay dialed in.”

Takco operators have had positive experiences with the HB365LC due to its reliable performance.

Boswell stated, “Our operators have enjoyed it. They like the reactiveness of the machine, and it’s been running hard without any issues and keeping up with what we put it through.”

Advancing into the future

As Takco looks ahead, it is prepared to continue its growth and success in the industry. By embracing innovative equipment like the Komatsu HB365LC hybrid excavator, the company is setting a precedent for efficiency and productivity in its projects.

“We want to continue growing and taking on larger, more challenging projects at a variety of new locations across the United States,” said Lowery.

Boswell encourages potential customers to consider the HB365LC for their own operations, given Takco’s positive experience with the machine.

“If it’s possible, ask your sales representative to let you demo one or rent one to see for yourself how much it can reduce your fuel consumption and impact your productivity,” Boswell suggested. “From our standpoint, it’s been a great machine.”

Hybrid HB365LC-3 excavator offers significant fuel savings and helps reduce your carbon footprint with lower emissions

Hybrid HB365LC-3 excavator offers significant fuel savings and helps reduce your carbon footprint with lower emissions

Looking for ways to increase production while reducing costs? In today’s economy with diesel prices higher than ever, using a hybrid excavator such as Komatsu’s Hybrid HB365LC-3 is a solid solution, according to Kurt Moncini, Senior Product Manager, Komatsu.

“Hybrid technology continues to grow and be adopted in the automotive world, and the construction industry is coming around to the benefits such as lower fuel costs and emissions,” said Moncini. “The HB365LC-3 offers increased fuel efficiency without sacrificing power, so the overall performance is outstanding. A topper on the cake is the added benefit of reduced emissions that lowers your carbon footprint and promotes sustainability.”

Moncini continued, “Based on EPA’s (Environmental Protection Agency) CO2 formula, the Hybrid potentially offers an up to 20% reduction in CO2 emissions compared to the standard PC360LC-11. It’s a big win all around.”

Komatsu introduced the 36-ton Hybrid HB365LC-3 — the industry’s first true hybrid in that class size — in 2017. Since then, thousands have been used around the world for all types of excavation, loading trucks and to perform other tasks. The HB365LC-3 followed the introduction of Komatsu’s first hybrid excavator, which was launched in 2008.

“The Hybrid HB365LC-3 has equal or better performance than our standard PC360LC excavator, but with fuel savings that could be as high as 20%, depending on application,” said Moncini. “It’s a great fit for construction companies that use excavators in high-swing applications, as well as for feeding crushers in quarry, recycling and demolition applications where swing is a constant.”

An electric swing motor captures and regenerates energy as the upper structure slows down and converts it to electric energy.

Moncini explained, “It’s using energy that would normally be wasted and makes it available to do work, contributing to increased efficiency and decreased diesel usage.”

Highly responsive

The energy captured during each swing braking cycle is stored in the Hybrid HB365LC-3’s ultracapacitor. Each time the excavator swings, the capacitor discharges electric power to the electric swing motor.

He added, “When it comes to the boom arm and bucket, the capacitor drives the swing, and all available engine horsepower can go into the hydraulic system. This creates faster cycle time and a very quick, responsive swing. It’s snappy.”

Tier 4 and more

Komatsu recently improved the warranty on the HB365LC-3’s hybrid components. The special hybrid component warranty term is now up to seven years or 15,000 hours and covers the electric swing motor, motor-generator, capacitor and inverter. If you sell the excavator, the warranty is transferrable.

The Hybrid HB365LC-3’s 269-horsepower engine is a six-cylinder with a Komatsu aftertreatment system that meets U.S. EPA Tier 4 Final emissions regulations. A Komatsu Diesel Particulate Filter (KDPF) and Selective Catalytic Reduction (SCR) work together to inject Diesel Exhaust Fluid (DEF) and decompose nitrous oxide into non-toxic water and nitrogen.

Komatsu Care comes standard, including two complimentary KDPF exchanges and two SCR services during the first five years with unlimited hours. It also covers scheduled maintenance for the first three years or 2,000 hours. All work is done by factory-trained distributor technicians.

Hours and key performance data can be tracked remotely with Komtrax. Operators can see the information first-hand on the 7-inch, color LCD monitor, including a capacitor charge gauge, DEF levels and a rear-view camera. Komtrax has an Operator Identification System that records machine-operation and application data for up to 100 individual ID codes.

Operators will also appreciate lower noise levels in the spacious ROPS (roll-over protective structure)-certified cab. Features include vibration-dampening mountings and a fully adjustable, air-suspension seat and arm rests. A Bluetooth AM/FM radio is now standard on new machines.

“Users are raving about their productivity and cost savings,” said Moncini. “It’s not the right machine for every application or job site, but on those swing intensive jobs where it fits, it really stands out. We encourage anyone who uses excavators in the 36-ton class to contact their distributor for more information and to set up a demonstration.”
