What is the Function of the Ratchet in Chain Pully Block?

A manual chain hoist consists of numerous parts. What role does the ratchet play? A professional manufacturer of manual chain hoists gives you a detailed explanation:

The ratchet is the core component of the double‑brake system of a Manual Chain Pulley, which cooperates with the pawl to realize one‑way locking. When lifting heavy loads, pull the chain, the ratchet rotates forward and the pawl slides along the tooth surface for normal load lifting. Once pulling stops, the pawl immediately engages into the ratchet tooth grooves to stop reverse rotation of the ratchet, lock the load and prevent it from falling. When lowering the load, pull the chain in the reverse direction to disengage the pawl, enabling controlled rotation of the ratchet. The double‑brake ratchet structure improves braking redundancy, ensures safety during lifting operations and prevents unexpected slipping of the load.
