Komatsu’s PC490HRD-11 demolition excavator has made its North American debut at Demolition San Antonio, the National Demolition Association’s annual convention and expo, which took place on March 6-9.

A highly versatile machine that’s easily reconfigurable for changing work demands, the 362 HP (270 kW) PC490HRD-11 is engineered to help customers achieve higher efficiency at the demolition job site.

The PC490HRD-11 uses Komatsu’s in-house boom change system that includes 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.

The hydraulically expandable undercarriage of this new machine enables the tracks to be narrowed for transportation and expanded for working. The tilting demolition cab allows the operator to use joysticks to position the cab for an optimal view. The PC490HRD-11 offers six different working arrangements, with a boom extension for higher reach or extended digging boom.

For the first time in North America, Komatsu will also be featuring a special demolition specification of the 257 HP (192 kW) PC360LC-11 excavator at the show. The demolition version of the PC360LC-11 will be launched in the North American market within the next year.
