Soil compaction
and demolition
For dynamic soil compaction Liebherr offers an automated free-fall control system creat-
ing rope tension just before the drop weight hits the ground which reduces rope wear to a
minimum. Furthermore, this control system avoids any slacking of the rope on the winches
which is typical during free-fall applications.
Although demolition jobs present an extreme situation for operator and machine, the
design of the Liebherr hydraulic crawler cranes guarantees optimum stability even when
working with long booms. The large dimensions of the tubular booms enable lateral striking
with the demolition ball even at great heights.
