Telescopic Crawler Crane is a kind of new generation products,which is developed by our company and Dalian University of Technology.Now seven kinds of loading capacity are available,which are 25 tons,40 tons,50 tons,65 tons,80 tons and 100 tons. Our advanced and excellent-performanced Telecopic Crawler Crane fills the gap in domestic market, and will be an idea lifting equipment at present.
This machine combines the advantages of autocrane working without boom-disassembling and crawler crane working with load. The track chassis can be used in various working fields, with lower pressure t ground,more close to lifting load. The machine can pass through lower height for its flexible telescopic boom,usually as the replacement of autocrane and truss boom crawler crane with much large 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 machine also has the track span of hydraulic telescopic crane, with the advantages of convenient transportation when retracting and stable performance when extending.
Four outriggers are supported by hydraulic cylinder, while the distance between two crawler frames is adjusted by horizontal extending hydraulic cylinder.
