Mobile cranes divide into wheel type and crawler type .
The main difference between the two in the chassis.

Crawler type : The chassis is the same with tank , has big area of contact , it suitable for soft ground.
The advantages for crawler type : Less reduced ground pressure, less turning radius, free hoisting kicking operation, driving with loading , good lifting mobility.
What’s more , crawler type is a multi-purpose crane. It can pilling, earthwork, like this operations with the help of additional devices.
The disadvantages for crawler type: It can’t drive on the road, it have to be disassembly once carriage.
Because of the disadvantage of crawler type, small tonnage crawler crane has been gradually replaced by wheel type crane. But large tonnage crawler crane has more longer arm, more longer T.M , larger working width, the good capacity of driving with loading, the good capacity of adapting to the harsh ground. So it was widely used in large-sale projects.
