Principle Summary: The essence of a hand chain hoist is a “manually powered, self-locking, high-reduction-ratio gear crane.” · The key to saving effort lies in its high-reduction-ratio gear system, which allows for lifting heavy objects with minimal effort by requiring a long distance of movement. · Safety is ensured by the one-way friction plate brake, which utilizes the weight of the load itself to achieve self-locking, thus guaranteeing safety during operation. · The operation method involves repeatedly pulling the hand chain, and by controlling the engagement and disengagement of the brake, the hoist can be lifted, stopped, or lowered as needed.
