Crawler crane is a mobile crane; it consists of
track based vehicle and attached crane apparatus over it. The set of tracks gives the crane high stability in its position. These cranes are able to work on soft ground due to the weight dispersal properties of the tracks

The crane with crawlers can lift bigger weights than the one with rubber wheels. The crawler crane has a main advantage that it can move around the site freely without fixing problem. It also can move with the weight lifted by its ropes. But the disadvantage of the crawler crane is the enormous weight and the great size. Some of them are very large, so they must be taken apart and moved from site to another by truck or train.
The massive size gives the crane the ability of lifting massive loads can reach 3500 ton to big heights. For lifting these cranes generally use wire ropes connected to electric motor and may be a combination with hydraulic power. They can work at any type of land and any type of weather. Their high stability on the ground is because the big contact area between the crawlers and the ground.
