Round chain hoist for safe work and maintenance

- Jun 15, 2019-

When the Round chain hoists the weight upwards during the work, it will shake the manual chain and the hand wheel clockwise. When it descends, the chain will be pulled counterclockwise, the brake seat is separated from the brake pad, and the ratchet is in the pawl. Under the action of static, the five-tooth long axis drives the lifting sprocket to run in the opposite direction, thus smoothly descending the weight. The chain hoist generally adopts a ratchet friction plate type one-way brake, which can brake itself under load, and the pawl meshes with the ratchet under the action of the spring, so that the brake works safely.


The circular chain hoist is safe and reliable to a certain extent, and has high mechanical efficiency. The product has small pull force, light weight, easy to carry, beautiful appearance, small size and durability. It is suitable for factories, mines and construction sites. , docks, docks, warehouses, etc. are used to install machines, lifting goods, especially for open air and no power supply operations, showing its superiority.


The main parts of the circular chain hoist are made of alloy steel. The chain adopts 800Mpa high-strength lifting chain. The material is generally 20M2, medium frequency quenching heat treatment, low wear and anti-corrosion chain; high strength hook, the material is generally alloy steel The calendered hook design ensures a slow lift to prevent overload.
