[0002] In the production process, it is necessary to move goods and products to different heights. At this time, a hoist is needed to facilitate the lifting of goods. When using it, the materials are placed on the hoist basket and the goods are lifted by the basket. The current lifting equipment uses power methods such as cables, chains or screws, which can easily lift the basket and effectively save a lot of manpower and material resources. It is widely used in many fields, but it has the following defects:

[0003] Regardless of the power method used, the hanging basket will stop suddenly when it is lifted to the top and bottom, which will cause vibration force and easily cause damage to the hanging basket. Especially when it descends to the bottom, under the action of the hanging basket's own gravity, the vibration impact force it receives will be greater, and the hanging basket may also contact the bottom plate, which makes it more likely to cause the hanging basket to be damaged by the vibration impact force.

[0004] For this reason, we propose a lifting device with automatic shock absorption to solve the above problems. Utility Model Content
