Assembled crane sling

Abstract

The invention discloses a packaged crane hanger, which aims to provide an auxiliary machine of the crane with lifting height longer than the lever of crane and adjustable. The invention belongs to the technology field of lifting equipments and operations and comprises a suspender and hanging head and also a motion bar. The suspender is connected by basic bars on the front end and the rear end and one to five pieces of lengthening bars in the middle in series; the outer ends of the two basic bars are connected with the motion bar and the hanging head in turns; the lengthening bars are provided with balance hanging beams and lifting lugs on both ends; hook hanger shafts are provided on the lengthening bars symmetrical with the balance hanging beams to form three hanging nodes; the hanging head can extend and rotate along the three-dimensional direction. The hanger has adjustable length, convenient assembly and disassembly, convenient transport and saves storage space, which makes full use of the advantages of the mechanical work of the crane, greatly improves the working efficiency and safety of production and personnel and lightens the labor intensity of workers. The invention avoids the limit of the work height and space of the work place and is suitable for using in lifting equipments and components in various complicated environments like tunnels.

Description

Technical field [0001] The invention relates to hoisting and hoisting equipment, which is an auxiliary machine tool of the hoisting and hoisting equipment, and belongs to the technical field of hoisting equipment and hoisting operations. Background technique [0002] The existing hoisting and hoisting operation is to connect the hanging objects through standard pick-up devices such as hooks and grabs or use special spreaders with special functions, and rely on the action of the crane working mechanism to realize the lifting of the hanging objects, complete the lifting of the hanging objects in place and Install. But its basic limitation is: the lifting height of the hanging object cannot exceed the height of the working arm of the crane. Under the hoisting operation conditions where the working arm of the crane itself is not long enough, or the working arm cannot be raised due to the space height limitation of the workplace, the traditional hoisting method cannot be complet...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the lack of length of the working arm of the existing lifting equipment, or the limitation of the height and space of the hoisting work site, and the inability to realize the mechanized hoisting operation, the invention provides a lifting height greater than the height of the working arm of the crane, and the lifting height can be adjusted.
