Durable features and safe work of Hand Lever Hoist
Jul 07, 2018

When the manual hoist is used to lift the heavy object upwards, the manual chain and the hand sprocket wheel need to be rotated clockwise to some extent, and the chain is pulled counterclockwise when descending, and the brake seat will be separated from the brake pad during the production. The ratchet is stationary under the action of the pawl, and the long axis of the five teeth drives the lifting sprocket to run in the opposite direction, thereby smoothly descending the weight.

  

The manual chain hoist generally adopts its ratchet friction plate type one-way brake. Under normal circumstances, it can brake itself under load, and its pawl engages with the ratchet under the action of the spring, so that the brake can work safely. To a certain extent, it is safe, reliable, easy to maintain, high in mechanical efficiency, small in pulling force of the bracelet, light in weight and easy to carry, beautiful in appearance, small in size and durable. It is suitable for factories, mines, construction sites, docks, docks, warehouses, etc. It is used to install machines and lift cargo, especially for open air and powerless operation.

  

The main parts of the manual chain hoist are made of alloy steel. The chain is mainly made of high-strength lifting chain. Under normal circumstances, the material is 20M2 medium frequency quenching heat treatment, low wear and corrosion resistant chain; high strength Hooks are generally made of alloy steel. The calendered hook design ensures a slow lift to prevent overload and meets European CE safety standards.
