Chain block, also known as manual chain hoist, is a mechanical lifting tool that uses gear transmission to amplify manual force. Its main components include load chain, hand chain, gear system, braking device and hooks. The load chain is made of high‑strength alloy steel with heat treatment, ensuring tensile strength and wear resistance. The fully enclosed gear casing protects internal parts from dust and moisture, making it suitable for harsh working conditions.
The working principle relies on mechanical advantage: pulling the hand chain drives the gear set, which reduces speed and increases torque, allowing one person to lift heavy loads safely. The integrated brake system can hold the load automatically when pulling stops, ensuring operation safety.
In terms of application, chain blocks are widely used in construction for steel beam lifting, in manufacturing for equipment assembly and maintenance, in shipbuilding for component positioning, and in warehouses for cargo handling. With features like portability, easy operation and low maintenance, they remain essential equipment in modern industry.
