Utilizing the principle of mechanical counterweight balance—where the main shaft body and counterweight block maintain equilibrium—this system achieves lifting and lowering operations without requiring external power sources such as motors, assist springs, or gas struts. Operation is effortless, straightforward, convenient, and safe. It remains unaffected by power outages and requires no maintenance.
