In order to facilitate a quick relocation of the smallest Liebherr construction crane SK 20 a rapid rigging method was developed. It consists of a 2 axle lagging device as well as a swan neck for attaching it to a tractor. The Liebherr rapid deployment crane is coupled between the swan neck and the lagging device. Therefore the travelling speed of the crane is much higher in semi-trailer mode than it would be as a towed trailer. 23 x 3.2 x 5.8 cm.
