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.
