The hoisting equipment has the working characteristics of intermittent movement, namely corresponding mechanisms for taking materials, transporting, unloading and the like in one working cycle alternately work, so that the development and the use of the crane on the market are more and more extensive. Because the weight is lifted without the supporting legs and the lifted weight is frequently used for driving, the driving speed is higher than that of a crawler crane (crawler crane); the operation is stable, the lifting capacity is large, the lifting can be carried out within a specific range, but the road is required to be smooth and firm, the tire air pressure meets the requirement, and the lifting distance from the ground is not more than 50 CM; long distance walking with load is prohibited. In order to ensure the operation safety, the lifting operation without landing legs is basically forbidden in China at present. The crane is matched with steel wire ropes of various types including phosphated coated steel wire ropes, galvanized steel wire ropes and polished steel wire ropes.

When an existing portal crane is used, the existing portal crane is often lifted and moved, and due to the fact that a lifting rope is long, the swinging amplitude of the lifting rope is large in the moving process, and a lifted object is easy to collide, so that the anti-collision protection device for lifting the crane is provided.
