[0002] A lifting platform is a type of lifting machinery used to transport people or objects vertically. It also refers to equipment used for vertical transportation in logistics systems such as factories and automated warehouses. Lifts are often equipped with various flat conveying devices, serving as a connection between conveyor lines at different heights. Because the lifting platform must lift cargo to a certain height during use, the cargo may fall from the platform during the lift, posing a certain risk. Therefore, a protective frame is required around the lifting platform. Currently, the protective frame often has a port for cargo handling.

[0003] When some of the current protective frames are in use, since the goods to be transported are of different sizes, when transporting larger goods, if the transport opening on the protective frame is small, it may affect the operator's ability to transport the goods to the lifting platform, thereby affecting the working efficiency of the device. Some of the current devices are unable to adjust the size of the device and the size of the transport opening well when in use.

[0004] Therefore, a protective frame for a lifting platform with a variable size is proposed. Utility Model Content
