Purpose-built excavators
NDA show allows attendees to operate equipment designed to help make demolition more efficient
Komatsu showcased its PC360LC-11 and PC490HRD-11 demolition excavators at the National Demolition Association’s (NDA) Annual Convention & Expo. During the live demonstration event, attendees could operate the PC360LC-11, which features a straight boom that increases reach by up to 26% compared to a standard excavator.
The 257-horsepower, 78,551-pound PC360LC-11 is one of three new straight boom demolition excavators with easy customization that allows users to program up to 15 different tools. The Komatsu PC290LC-11 and PC490LC-11 models are also available. These machines are built to tackle tough demolition jobs with robust protection elements like heavy-duty revolving frames and underguards, a bucket cylinder guard, boom light protection guards, and reinforced attachment linkage. The PC360LC-11 has a maximum digging height of 42 feet, 5 inches.
“All of our straight booms are factory plumbed with Plus II hydraulics, so you can run a wide variety of attachments,” said Matt Buerstetta, Product Manager, Demolition Excavators, Komatsu. “Operators can program tool controls in the monitor for pressure and flow. The PC360 is ideal for small residential and commercial sites where sorting and manipulating material is part of the demolition.”
Faster attachment switches
Komatsu’s PC490HRD-11 high-reach demolition excavator features the K100 boom change system that enables operators to begin working within minutes of arriving at a jobsite and minimizes time for boom changes as the job progresses. Operators can quickly switch attachments from the cab, making changes faster and safer than old methods of removing pins and hoses and then reattaching them. The machine can reach up to 104 feet and includes a full demolition guarding package, excellent visibility from a 45-degree tilting cab, and informative and intuitive controls.

“The PC490HRD-11 can be easily moved from job to job,” noted Buerstetta. “With the K100 system, you could have the high-reach boom move down to the mid-reach and short-reach boom, all with a touch of a button from the cab. And, it can be done in a couple of minutes.”
Komatsu’s additional product lines of Lehnhoff quick couplers and Montabert demolition attachments can be paired with these demolition excavators to increase versatility further.
“We got a lot of positive feedback from the show. Attendees were very impressed and happy with our machines and attachments,” stated Scott Ruderman, Product Marketing Manager, Komatsu. “NDA gives us the opportunity to show Komatsu’s dedication to the demolition industry with purpose-built machines like the PC360LC straight boom and the PC490HRD, as well as having a large number of personnel on hand to answer questions. We’re looking forward to next year.”
