It also refers to equipment that performs vertical transportation in logistics systems such as factories and automatic warehouses. When the workshop lift is lifting, if there are people at the bottom of the lift, there will be a major safety hazard. Therefore, a safety protection device is required to prevent people from entering the bottom of the lift during lifting.

[0003] In the prior art, when the lifting platform is lifting and protecting itself, the surrounding fences are closed for protection, and the lifting platform is driven up by a hydraulic rod to transport goods. However, in actual use, since the fence of the lifting platform usually adopts an independently fixed structure, when closing the fence, the fence is usually locked manually. However, the independently fixed fence still has the risk of being opened by someone, and there is a possibility that someone will open the fence and enter the bottom of the lifting platform. Therefore, it is necessary to improve a workshop lifting platform safety protection device to solve the above problem. Utility Model Content
