Deep foundation work with crawler cranes

Deep Foundation

Going underground

LR crawler cranes serve as optimal carrier equipment

Crawler cranes can be used as carrier machines for deep foundation work. With fixed or swinging leaders attached, they are ideal for use as piling or drilling rigs. Long booms and large radii enable extensive working ranges as well as enormous effective lengths. In addition, the LR cranes are particularly suitable for dynamic ground compaction.

Piling rig with swinging leader

The leader hangs on a special traverse. Raked impact driving of especially long steel or reinforced concrete impact driven elements is thus possible. Swinging leaders are often used for embankment work.

Piling rig with fixed leader

The combination of crawler crane and solid lattice boom leader provide a deep foundation machine for piling and drilling work which has a remarkable effective length and large radii. Hammer or rotary drive can be driven directly by the on-board hydraulics of the LR 1300.

Drilling rig

A fixed leader is fitted on the carrier machine LR 1300. Hence a drilling machine is created for the installation of cast-in-place piles using the continuous flight auger drilling method. Drilling depths down to 50 metres can be achieved.

Soil improvement, deep compaction

Using vibro-replacement the prevailing ground is improved through dynamic energy input. The vibro-flot is mounted free hanging on ropes and sunk into the ground. Through the vibration the surrounding soil is compacted.
