[0002] The traction mechanism and the platform lifting arm mechanism together form a large lifting platform, which is mainly used in logistics and warehousing systems. The lifting platform is a lifting machinery that transports people or objects vertically. It also refers to equipment for vertical transportation in logistics systems such as factories and automatic warehouses. The lifting platform is often equipped with various flat conveying equipment as a connecting device for conveyor lines at different heights. It is generally driven by hydraulics, so it is called a hydraulic lifting platform. In addition to being used as a cargo transportation at different heights, it is widely used in high-altitude installation, maintenance and other operations. The free lifting characteristics of the lifting platform have been widely used in municipal maintenance, cargo transportation at docks and logistics centers, building decoration, etc. It can walk freely after installing automobile chassis, battery car chassis, etc., and the working height space has also changed. It has the advantages of light weight, self-propelled, electric start, self-supporting legs, simple operation, large working surface, and the ability to cross obstacles for high-altitude operations, etc. 360-degree free rotation.
