Description

Technical Field

[0001] The utility model relates to the technical field of hoisting systems, and more precisely to a hoisting system applied to pulsating assembly of aircraft engines. Background Art

[0002] Aircraft engine final assembly can be broadly divided into assembling the engine's external piping and fitting the corresponding accessories, including the casing. These piping and accessories are located around the engine's circumference. Since aircraft engines are generally cylindrical and large in diameter, the assembly process requires the engine to be rotated about its axis for position adjustment. Currently, this adjustment is performed manually during the assembly of different components. Furthermore, current engine final assembly is performed at a single station, lacking the technical potential for modern, pulsating production.

Engines at various stations can be transported on rails, rolled, and raised and lowered according to specific assembly requirements. The use of electrified equipment can significantly reduce engine assembly time and improve comfort and convenience.
