Large equipment hoisting chain connection device with a hanging cover

Abstract

The chain type connecting device for hoisting large equipment with a hanging cover belongs to the technical field of hoisting large equipment, and solves the problems of large weight, high cost and large installation difficulty caused by large unloading buckle and large diameter steel wire rope in the connection of the existing hanging cover type lifting lug. The technical scheme points include that the upper ends of the multiple hoisting belts are connected or wound on the hoisting hook of the crane, and the lower ends are connected or wound on the upper pin shaft of the chain type lifting device; the chain type lifting device is composed of two blocking rings, an upper pin shaft, two chain plates with upper and lower connecting holes and a lower pin shaft; the hanging cover lug plate is located between the lower ends of the chain plates, and the lower pin shaft penetrates the lifting hole and the lower connecting hole of the chain plate; the hoisting belts are distributed as at least one strand between the chain plates, and the rest between the chain plates and the blocking rings. The main purpose is to realize safe and flexible connection with low cost and high efficiency in the hoisting of large equipment.
