When the rigid chain works, the platform is contacted and lifted, in this way, the force transmission no longer passes through the scissor fork structure, and the scissor fork only serves as a guide for the lifting platform. Compared with the lifting force required by the operation of the hydraulic lifting platform, the lifting platform driven by the rigid chain only needs 1 time of force, so that the loads of the shaft and the bearing in the scissor fork structure are greatly reduced. Another significant advantage is that hydraulic oil is no longer required, and the rigid chain can guarantee very high positioning accuracy and stability in a stop position for a long time based on the rigid nature of the chain itself. Compared with the problems of belt stretching of a belt type lifting platform or valve block sealing of a hydraulic lifting platform, the rigid chain positioning is almost free of errors.

When the movement of the scissors fork is stopped, the electromagnetic valve is powered off, and the hydraulic cylinder is kept pressure without a rod cavity, so that self-locking is formed. The self-locking protection of the lifting platform is realized when the power of the scissors fork is invalid.
