Reaching Higher
PC490HRD-11 demolition excavator helps increase efficiency with fast boom change system, reach of up to 105 feet
From hammering to processing to loading, demolition often involves quickly changing tasks. With easy attachment switches and the ability to work at heights of up to 105 feet, Komatsu’s new PC490HRD-11 high-reach demolition excavator helps achieve greater efficiency, according to Matt Buerstetta, North American Product Manager for Demolition Machines, Komatsu.
“The PC490HRD-11 is a highly versatile machine that’s easily reconfigurable for changing work demands and can run a wide variety of attachments, including grapples, hammers, processors and buckets,” said Buerstetta. “One of the biggest advantages is our K100 boom change system that lets operators quickly switch out booms. What would normally have taken up to a day in the past can now be done in a mere fraction of the time.”
The in-house K100 boom change system uses oversized quick connectors for the hydraulic lines that minimize back pressure and oil heating without restricting oil flow. The system also features hydraulically powered pins mounted inside the main boom structure to help reduce the risk of damage to the equipment during reconfiguration. With the K100 system, operators can easily reconfigure the machine from the cab, improving safety, productivity and efficiency.
Expandable undercarriage
The PC490HRD-11 has a base weight of 128,199 pounds and a weight of 161,500 pounds with the extended high-reach boom. At full extension, it can handle a maximum attachment weight of 5,512 pounds. A 360-degree Working Range Indicator system with side stability provides a pre-alert function.
A hydraulically expandable undercarriage enables the tracks to be narrowed for transportation and expanded for working. The tilting demolition cab can be tilted up to 45 degrees and allows the operator to use joysticks to position the cab for an optimal view.
Full demolition guarding helps protect components and keep the PC490HRD-11 running in harsh conditions. It has guards on the revolving frame and undercover, as well as level two window guards for the front and top glass. A dust protection system minimizes dust and debris in the engine and cab.
Model | Horsepower | Operating Weight | Maximum Reach |
|---|---|---|---|
PC490HRD-11 | 362 hp | 128,199-161,500 lbs.
| 105 ft. |
“The PC490HRD-11 has a heavier counterweight, coming in at about 18 tons, which is bigger than our standard PC490 excavator,” said Buerstetta. “It has been a proven winner in Europe for several years already. We’re excited to bring it to the North American market, and we encourage anyone who has large demolition work and wants a versatile machine that will handle a wide variety of tasks to contact their local distributor.”
