The main advantages of truck cranes are fast traveling speed, rapid movement, small damage to the road surface, suitable for large mobility, often change the location of the operation.
The biggest advantage of mobile crane is movable, flexible, safe and reliable. Reasonable size, light weight, easy operation of the trolley, can easily complete the manual or electric movement, and can quickly and reliably convey the workpiece and improve the speed.
The advantages of Crane Truck in general are:
1. Ease of movement. With its lifting performance and appearance of the size of the conditions, can be lifted to accept the lifting of most of the factory or workshop lifting work.
2. without overhead tracks and other fixed structures, but also to reduce the infrastructure of some unnecessary investment and production costs and maintenance costs.
3. There are unique power supply devices, without the installation of feeder wires and contact with conductive equipment.
