Mobile crane are several?

    Mobile crane is rotating jib crane. Since the power system on its own drive, also known as self-propelled cranes, which used to be called pneumatic tire assembly wheeled cranes. Mobile overhead gantry crane  can travel long distances and flexible conversion job site, mobility, and therefore widely used.

There are mobile crane truck crane, tire cranes and crawler cranes, their characteristics are briefly described below.

1. Used truck crane chassis, with a car driving through the performance, speed is high. Disadvantage is running can not load, lifting legs must fight. But because of its flexible, fast transfer characteristics, making the use of mobile cranes largest amount cranes.

2. Crane uses a specially designed tire tire chassis, wide track, good stability, can work around all sides, on flat ground without legs can load driving. In other countries, especially off-road tire tire hoist gantry crane  more widely used, much to replace cranes trend.

3. Crawler crane with crawler chassis, walking by the crawler crane. Compared with the wheeled crane has its outstanding features: Crawler large contact area with the ground than live small, in the soft, muddy ground operations; traction coefficient is high, climbing degree, you can travel on bumpy field; crawler bearing wide, good stability, generally do not need to set outrigger devices. Weakness is cumbersome,bridge gantry crane slow driving on pavement damage effects, higher manufacturing costs.
