[0002] Scissor lift platforms are specialized vertical lifting equipment with wide applications both indoors and outdoors. They can be widely used for equipment maintenance, mechanical installation and repair in stations, docks, bridges, halls, and factories, as well as building maintenance. Scissor lift platforms are primarily used in the logistics industry, production lines, and for lifting and unloading goods between basements and floors. They can also be used for lifting stages and operating platforms. The products are characterized by their stable structure, low failure rate, reliable operation, safety, high efficiency, and simple and convenient maintenance.

[0003] A scissor lift platform, as disclosed in patent application CN212769638U, includes a support mechanism, a pallet mechanism, and a lifting mechanism.
