Indef Chain Pulley Block

Product Description

A Chain Pulley Block (also known as a chain block or manual chain hoist) is a mechanical device used to lift and lower heavy loads vertically with minimal physical effort. It is highly valued for its simplicity, portability, and ability to operate without electricity.

Key Components

• Hand Chain: The operator pulls this chain to initiate the lifting process.

• Load Chain: A high-tensile steel chain that holds the weight of the load.

• Gears & Sprockets: Internal mechanisms that multiply the force applied to the hand chain.

• Hooks: One top hook to secure the block to a support beam and one bottom hook (with a safety latch) to grab the load.

• Braking System: An automatic mechanical brake (often a ratchet and pawl) that holds the load securely in place when the operator stops pulling.
