Description

Technical Field

[0001] The utility model relates to a hoisting device, in particular to a hoisting device for a mobile combined electrical appliance air chamber, belonging to the technical field of hoisting. Background Art

[0002] The combined electrical air chamber is a studio where electrical equipment such as pipelines, storage tanks, compressors, distribution boxes or air compressors are installed. Since various electrical equipment has its own installation position, it is necessary to operate the electrical equipment when assembling each electrical equipment. Since the electrical equipment is heavy, it is necessary to use a lifting device to lift the electrical equipment to facilitate the operation and disassembly of various electrical equipment.
