New attachments are extending the role of crawler excavators from high production earthmovers into heavyweight demolition tools with a huge reach.
Volvo's latest offering for its EC360 crawler excavator is not just a bolt-on concrete nibbler but a complete demolition arm folded up for delivery into city centre sites in a 7.4m long by 3.1m high cradle.
Demolition specialists crowded round Volvo's open air stand as the brand new piece of kit was hitched on to the long undercarriage crawler excavator. After only 20 minutes the pins were inserted, the hydraulic connections were coupled up and the arm was waving about above the Bauma exhibition stands, showing off its 20m vertical and up to 11m forward reach.
The three-piece demolition attachment was developed for Volvo by Kocurek Excavators of Ipswich, UK. There will be a similar attachment for the EX460 crawler with a pin height of 26m and outward reach of 14m. Necessary additional accessories are a tilting seat for the operator to avoid neck strain when working high up, and beefed up cab and undercarriage protection.
