The utility model provides a prevent that hot rolling coil of strip from spilling over limit and hanging wounded overhead traveling crane clamp, belongs to overhead traveling crane equipment technical field for damage hot rolling coil of strip spills over the limit when preventing to hoist the hot rolling coil of strip. Its technical scheme is: keeping apart the brass welt for two and fixing respectively in the inboard of original brass welt of overhead traveling crane clamp, the upper end that keeps apart the brass welt is less than the upper end of original brass welt, and the length of keeping apart the brass welt is lighter than the thickness of coil of strip, and isolation brass lining plate thickness is greater than the coil of strip outer lane and overflows limit standard length. The utility model discloses the installation can make the inboard production of coil of strip outer lane part and original brass welt can hold the clearance of overflowing the limit after keeping apart the brass welt, and when the coil of strip took place to overflow the limit, overhead traveling crane clamp and belted steel contact back original brass welt in clamping process can not touch the limit of overflowing of coil of strip, has prevented effectively that the coil of strip outer lane from overflowing limit production turn -up or hang the wound with the coil of strip lifting by crane the in -process in the clamping process of overhead traveling crane clamp, has guaranteed the outward appearance image and the quality of coil of strip.
