[0002] Goods elevators are a type of mechanical equipment for multi-functional lifting of goods, usually used in the field of goods handling and loading / unloading. According to different structures, they can be divided into: fixed type, guide rail type, scissor type, and chain type goods elevators. Among them, scissor type goods elevators are widely used due to their advantages of strong mobility, large load-bearing capacity, and high goods lifting efficiency.
[0003] Currently, the common scissor type goods elevators mainly consist of a working platform, a scissor type lifting mechanism, a traveling mechanism, and a control system. Among them, the working platform is mainly used for supporting and transferring goods.
