The undercarriage is 6 meters long and 4.7 meters wide. The tracks have a 0.7 meter breadth and are 1.28 meters heigh.
The undercarriage can be retrackted to a breadth of 3.4 meters for the transport over the road.
The counterweight weights 24 tonnes and exists out of two 5.4 tonne slabs and a 13.2 tonne slab. The tailswing is 4.37 meters.
The crane was fitted here with a 46 meter main boom. In this configuration the crane can maximum lift 13.8 tonnes on a 10 meter radius and 2.5 tonnes on a 35 meter radius.
The crane is powered by a Caterpillar 3306 diesel engine with 241 hp.
The crane operator has a very good overview on the construction site using this cab-lift, originally from Sennebogen.
The crane looks very well maintained, in 2011 this crane was overhauled.
