The rear end face of the clamping frame is provided with a plurality of bolt holes for adjusting the extension length of the anti-collision clamping strip.

Preferably, the movable connection mode is bolt connection. The clamping frame is provided with a round hole, the round hole corresponds to a fastening bolt of the force application end of the clamp claw, the anti-collision device is fixed by using the clamp claw fastening bolt, and the anti-collision device is fastened by using the bolt of the clamp claw body, so that the strength of the clamp body cannot be influenced.

Preferably, the fixing mode of the anti-collision clamping strip is that a plurality of fixing holes are formed in the upper surface and the lower surface of the anti-collision device, and the anti-collision clamping strip is fixed in a mode that screws are pressed into the anti-collision clamping strip.

Preferably, the anti-collision clip strip is designed as wear-resistant rubber; the cost is very low, and when the wear of the steel plate reaches a certain amount, the steel plate is replaced, so that the long-time use effect of the steel plate is ensured. The anti-collision device is designed with the wear-resistant rubber 20-40 mm higher than the end face of the clamp claw, the width is equal to the width of the hollow frame of the clamp claw clamping frame, the problem that the metal end face of the clamp claw collides with the outer package of the steel coil can be effectively solved, and the service cycle of the anti-collision device wear-resistant rubber can be ensured to meet the production requirement.

Preferably, the through holes are rectangular through holes or circular through holes.

The crane clamp anti-collision device produced according to the scheme has the following beneficial effects:

the anti-collision device is added to the end part of the clamp claw, so that the side surface of the force application end of the clamp claw of the crane is effectively prevented from being in direct contact with the side surface of the steel coil, the finished steel coil outer package and the steel coil body are well protected, and the lifting safety is not affected.
