6-10Ton And 12-25Ton Truck Mounted Cranes According to the chassis, there are two types of tire cranes and truck cranes: the former adopts a special chassis, the vehicle body is short, and the operation is flexible; the latter's lifting operation is installed on the chassis of the vehicle, and the vehicle body is long, and has the driving performance of the truck. A single machine can be quickly transferred or driven with a car formation. Compared with the car crane, the advantages are: wide track, good stability, short body, small turning radius, and can work in the 360 0 range. However, when driving, the road surface is required to be higher, the driving speed is slower than that of the car type, and it is not suitable for working on the soft and muddy ground. A boom-rotating crane that uses a tire-type chassis to walk. It consists of two parts: boarding and getting off. The upper vehicle is a lifting work part, and is provided with a boom, a hoisting mechanism, a luffing mechanism, a counterweight, a turntable, and the like; the getting-off is a support and a walking part. The upper and lower vehicles are connected by a Slewing Ring. When lifting, it is generally necessary to lower the legs, increase the bearing surface, and level the fuselage to ensure the stability of the crane.
