[0002] Crane is the common name for cranes such as cranes, overhead cranes, and overhead cranes. Cranes are basically the same as what we call cranes. There are basically two types of crane drive methods: one is centralized drive, that is, a motor drives a long drive shaft to drive the active wheels on both sides; the other is separate drive, that is, the active wheels on both sides are driven by a motor each.

[0003] Medium and small bridge cranes mostly use a "three-in-one" drive method that combines brakes, reducers and electric motors. For ordinary bridge cranes with large lifting capacity, in order to facilitate installation and adjustment, the drive device often uses a universal coupling, which requires anti-collision limiters during the sliding operation of the crane.

[0004] The existing anti-collision process cannot adjust the anti-collision strength according to the tonnage of the vehicle, and the anti-collision effect is poor, which is not convenient for achieving multiple shock-absorbing effects; therefore, it does not meet the existing needs. We propose a slider bracket with an anti-collision structure. Utility Model Content
