The rigid chain lifting platform is a mechanical device that achieves vertical lifting through rigid chain transmission. The motor drives the chain to rotate and mesh to form a rigid support column, driving the platform to rise and fall smoothly. Similar to "screw transmission", its rigid characteristics make it stable and less likely to bend under high loads.
