[0002] A crane refers to a multi-action lifting machine that vertically lifts and horizontally transports heavy objects within a certain range.

[0003] Currently, there are many types of cranes, and truck-mounted cranes are one of them. The current truck-mounted cranes are composed of a cab, a lifting main beam, and a hydraulic telescopic rod.

[0004] When the existing truck-mounted crane is in use, both the lifting main beam and the hydraulic telescopic rod are exposed. When lifting operations are carried out outdoors or in multiple building environments, if the driver operates improperly, the hydraulic telescopic rod under the lifting main beam may collide with an object or a nearby building, which is likely to cause deformation and damage to the hydraulic telescopic rod.

[0005] Therefore, it is necessary to provide an anti-collision main beam for a crane to solve the above technical problems. Summary of the Invention

[0052] A plurality of anti-collision components 8, a plurality of the anti-collision components 8 are respectively arranged on the surface of the protective sleeve 41.

[0053] The buffer component 6 includes two connecting sleeves 61, the surfaces of the two connecting sleeves 61 are both provided with first buffer members 62, and one side of the first buffer member 62 is connected with a buffer block 63.

[0054] The two connecting sleeves 61 are fixedly connected to the surface of the protective sleeve 41, two first buffer members 62 are connected to the surfaces of the two connecting sleeves 61, and the shapes of the connecting sleeves 61 and the buffer block 63 are both adapted to the shape of the protective sleeve 41.
