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.
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.
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.
