Cmax Self-Propelled Crane Telescopic Crawler Crane 

Telescopic crawler crane is a self-propelled crane. Crawler belt ground contact area is bigger. Traffic ability characteristic and the adaptability are good. It is applicable to the operation site in uneven areas, such as oil field, mining area, construction site, freight depot, wharf and other construction site; especially the low specific pressure area of wetland type area, such as marsh; and desert area that the wheel crane and others can’t work normally. This crane can play its special performance better in the area. The crane is mainly used for hoisting, load and unload, and short distance driving on load of construction machinery. And it also can make the laying into the ditch, docking, installation and repair of pipelines. It can be used in petroleum, chemical, mining, city construction, water conservancy and other large-scale projects. Meanwhile, it can be used as a general hoisting machinery for cargo loading and unloading, hoisting, stacking, equipment installation work, etc.


1. Telescopic boom crawler crane combines the advantages of telescopic boom crane and crawler crane.

2.Advantages over truck crane: high off-road performance,no need of leg support, capability of travelling at load, less operating space,excellent maneuverability, small turning radius.

3. Advantages same as truck crane: telescopic boom,excellent maneuverability and no need of disassembling, no field assembling to save time and labor with high efficiency and convenience.

4. Advantages over crawler crane with truss boom: convenient,no need of disassembling/assembling, easiness for reposition,fewest operating space not restricted by the space.

5. Advantages same as crawler crane with truss boom: low ground pressure and small turning radius, all-weather outdoor operation not restricted by the space.
