The end cover of the refrigerator is generally positioned at the height of about 2 meters, has a large size, can weigh more than 100kg, is carried manually, has low efficiency and has safety risks.

For the existing hoisting equipment, such as the chinese patent application CN109384153A, a telescopic crane is disclosed, which uses a motor vehicle as power output and has large overall volume and size. For equipment workshops, gaps among refrigerating machine equipment are small for space utilization, and the hoisting equipment cannot enter and is difficult to use.

And the fixed hoisting device at the top of the travelling crane and the like is adopted, because the cleaning frequency of the cooler of the refrigerator is not high, if 10 refrigerators are stored in one workshop, each refrigerator cleans one side every 6 months, and the whole workshop only needs to be cleaned for 20 times for one year, so the cost of adopting the fixed hoisting device is overlarge.

Therefore, a tool which is simple and convenient to disassemble and assemble, small in size and capable of quickly hoisting the end cover of the refrigerator is urgently needed.
