In the maintenance and servicing process, the lift plays a crucial role, and its excellent performance and high quality are directly related to the personal safety of maintenance personnel.

[0003] An aircraft engine is the core component that gives an aircraft the power to soar in the sky. Its main types include piston engines, gas turbine engines, and ramjet engines, each of which demonstrates highly complex and precise thermomechanical technologies. Known as the "flower of industry", the aircraft engine is not only the heart of the aircraft but also a key factor determining the performance, reliability, and economy of the aircraft.

[0016] Beneficial effects

[0017] The utility model provides a lifting device for engine maintenance, which has the following beneficial effects. The lifting device for engine maintenance can realize the flexible extrusion and limit fixation of engines with different shapes through components such as a lifting adjustment structure, a horizontal adjustment drive machine, a horizontal bidirectional threaded rod, an arc support block, a concave lifting extrusion limit block, and a lifting extrusion threaded rod. This flexible design can better adapt to engines with different shapes and sizes, avoiding damage or mismatch problems that may be caused by rigid fixation.
