The engine is a Cummins QSB6.7 with 240 hp. The two hoist winches have a capacity of 8 and 5 tonnes.

For the transport over the road is it possible to retrack the undercarriage to 3 meters, the leader can be folded down by hydraulics. The total height is then 3.6 meters only, the length is 19.2 meters.
