Komatsu high-reach for a knock-out knock-down

Digger Blogger | 13:15, Wed March 06 2019

The new PC490HRD‐11 is the latest in Komatsu’s range of heavy‐duty demolition excavators.

It is a 60‐tonne class machine that can be configured in six different working arrangements. It carries a 2.0-tonne demolition tool up to a height of 32 metres, a 3.34-tonne attachment up to 28 metres height or a 5‐tonne demolition tool up to 17.4 metres.

It has been designed and developed, incorporating customer feedback, by Komatsu UK (KUK) in Chester-le-Street, County Durham.

Operating weight of the PC490HRD‐11 ranges from 55.2 tonnes to 73.4 tonnes. Its Komatsu EU Stage V compliant engine puts out 270 kW / 362 HP at 1.900 rpm.

It has been designed to be easily re‐configured for changing work demands. Komatsu’s in‐house boom change system includes oversized quick connectors for the hydraulic lines, to minimise back pressure and oil heating, without restricting oil flow. Hydraulically powered pins are mounted inside the main boom structure to reduce risk of damage.

For transport purposes, every section of the working equipment has tie down points and lifting eyes to allow the equipment to be lifted and secured onto a trailer.

The new excavator’s undercarriage is mechanically variable in standard version to keep the weight down. The optional hydraulically variable undercarriage makes it easier and quicker to set up the machine on site, changing from transport width of less than three metres to a working width of nearly four metres.

Little features for operator convenience include front screen wiper and cab tilt functions that can be triggered without the operator taking their hand off the main controls.
