Abstract

The invention relates to a lifting appliance for transferring a heavy forklift portable frame. The lifting appliance comprises a hooking assembly and a lifting chain assembly; the hooking assembly comprises a cross beam and two lifting hooks, and the lifting hooks are located at the two ends of the cross beam; lifting handle ends are arranged at the upper ends of the lifting hooks, and hook bending ends are arranged at the lower ends of the lifting hooks; the lifting handle ends of the two lifting hooks are movably connected with the cross beam through pin shafts, and the hook bending ends of the two lifting hooks are located below the cross beam; the bending direction of the hook bending ends faces the outer side of the cross beam, and the lifting hooks rotate relative to the cross beam through the pin shafts; and the lifting chain assembly comprises a main lifting ring and two lifting chains, one end of each of the two lifting chains is connected to the main lifting ring, and the other ends of the two lifting chains are connected with the lifting handle ends of the two lifting hooks. According to the lifting appliance, the work efficiency is improved, labor intensity is reduced, the lifting design in an outward expansion manner is adopted, the opening size of the two lifting hooks is large, one lifting appliance can meet the requirement for lifting the portable frame with a plurality of opening sizes, and lifting transferring safety is improved.

Description

technical field [0001] The invention belongs to the field of forklift mast hoisting, and in particular relates to a spreader used for heavy-duty forklift mast transfer. Background technique [0002] The existing forklift gantry hoisting and transfer mostly use ordinary chain hooks or modified scissors pliers for lifting. The existing lifting methods have the following defects: (1) Chain hook method: chain hooks need to be hung at multiple points, and Appropriate lifting holes are required to operate; the hook is heavy, artificially connected, low operating efficiency, high labor intensity, long hanging cycle, not suitable for fast-paced production sites; the workpiece is also required to be relatively firm, Uniform safety lifting points; if there are too few lifting points, the stability during the lifting process will be poor; (2) The hanging method of the reformed scissors spreader: the mast has a large dead weight, generally close to 1 ton, safe The performance is poor, ...
