Although manual chain hoists need the same manual operation, but its use will bring a lot of convenience for lifting heavy objects, if you need to lift heavy objects up, just pull the manual chain hoist hand chain clockwise, the resulting hand wheel rotation, Driving lifting sprocket rotation, lifting the heavy lifting chain.
When heavy objects need to be released, the hand chain hoist manual chain is pulled counterclockwise, so that the brake pads are separated from the brake pads, the ratchet is still under the action of the pawls, the long axis of the five teeth drives the lifting sprocket to run in the opposite direction, Thus a steady decline in heavy objects.
Under normal circumstances, manual chain hoists are not only equipped with one-way ratchet friction plate brake, the brake can be self-loading, but also used the G80 chain. This kind of lifting chain is made of high-quality alloy steel and is produced with advanced assembly line production equipment, belonging to a kind of high-strength lifting chain.
Hand chain hoist G80 lifting chain in the production process in strict accordance with the implementation of production standards, but also its surface was polished, black, dipping paint, hang plastic, electroplating and other treatment to meet the large moisture, partial acid or Alkali and other harsh environments, manual chain hoist the safe use of provides a powerful guarantee.
Therefore, in general, hand chain hoist is a kind of lifting equipment which is safe, reliable, easy to maintain, high mechanical efficiency, small pulling force of the bracelet, light weight, easy to carry, beautiful appearance, small size, durable features, Much user's favor.
