Quick and easy self-assembly
Liebherr’s self-assembly system enables quick, easy and above all safe assembly of the cranes.
Self-assembly starts with the unloading of the basic machine. The Liebherr crawler crane raises
itself using four hydraulic jacks (Jack-Up System) onto solid support plates allowing the low
loader to simply drive away from beneath the raised uppercarriage. Subsequently the upper-
carriage unloads the side frames, counterweights and boom sections using either its A-frame
or boom foot, depending on the type of crawler crane. Thanks to the sophisticated design the
assembly of the side frames and the carbody counterweight is much easier using the self-as-
sembly system than using an auxiliary crane. It is possible to carry out all work concerning as-
sembly and change of equipment without an auxiliary crane. In addition, hydraulically activated
pins, quick connections and an auxiliary winch for reeving of the hoist rope both facilitate and
accelerate the assembly process. All boom configurations offered by Liebherr can be erected
by the cranes themselves. All exactly dimensioned rigging material provided is a prerequisite to
make this process and the remaining assembly so efficient.
