What type of mechanism does a power-operated hoist use to lock the drive when not in operation?

A power-operated hoist utilizes a ratchet-type mechanism to lock the drive when not in operation. This type of mechanism relies on a pawl that engages with the teeth of a ratcheted wheel to prevent movement in one direction. When the hoist is not in use, the ratchet engages securely, ensuring that the load remains stationary and cannot inadvertently descend or shift.

The ratchet-type mechanism is particularly effective in providing a reliable and simple means of locking, allowing for easy operation when lifting or lowering loads. It enhances safety by minimizing the risk of accidental release of the load when the hoist is not actively being operated.
