[0002] An integrated power unit generally refers to a device that integrates multiple functional components into a single device or system to achieve specific power transmission and control functions. An integrated power unit generally includes an engine, a transmission system, a control unit, and related accessories. Since an integrated power unit is generally large in size and has a certain weight, a hoist is required to be used for lifting during maintenance and disassembly of the integrated power unit.

[0003] When using lifting chains during the maintenance and disassembly of integrated power devices, the lifting chain is generally connected to the device together and then lifted directly. The lifting chain is in direct contact with the device shell, which makes the load easily exceed the maximum pressure that the device shell can withstand, causing the device shell to be squeezed, which is easy to cause squeezing damage to the device shell. Therefore, a buffer pad is placed between the lifting chain and the shell during lifting. It takes a certain amount of time to place the buffer pad, which makes the lifting efficiency low. It is also easy for the buffer pad to fall off, which can easily cause unstable lifting and personnel safety hazards. Therefore, we have proposed a lifting device for integrated power devices.
