Functions of Telescopic Crawler Crane
Telescopic crawler crane is a kind of new generation construction equipment. Our crawler crane with a telescoping boom fills the gap in domestic market, and will be an ideal lifting equipment in the future.

The telescopic crane combines the advantages of auto crane working without boom-disassembling and crawler crane working with load. The track chassis can be used in various working fields, with lower pressure to ground, which is more close to lifting load. The hoisting equipment can pass through lower height for its flexible telescopic boom, it is usually used as the replacement of auto crane and truss boom crawler crane with much larger tonnages. It is mainly applied to such following fields, such as under-bridge, inner-tunnel and other height restrained off streets area or frequent shifting yard. This telescopic boom crawler crane also has the track span of hydraulic telescopic crane, with the advantages of convenient transportation and stable performance.
