Quick and easy

assembly

A special feature from Liebherr is the time and cost saving self-assembly

and self-loading system. The auxiliary crane usually needed and its related

costs are eliminated thanks to this standardized system.

For transportation of the heavy hydraulic crawler cranes the crawlers have

to be removed from the basic machine. Self-assembly starts with the

unloading of the basic machine. The hydraulic crawler crane raises itself

using hydraulic jacks (Jack-Up System) allowing the low loader to sim-

ply drive away. Subsequently the uppercarriage unloads the crawlers,

counterweight and boom sections using either its A-frame or boom foot.

Hydraulically activated pins, quick connections and an auxiliary winch for

rope reeving facilitate and accelerate the assembly process. All boom con-

ﬁ gurations can be erected by the crawler cranes themselves.
