Principle of Hand Chain Hoist
Beijing Lingying's hand chain hoists are widely used, have many advantages, and have high body hardness, and are loved by many customers.
Features of hand chain hoist
By pulling the manual chain and the hand chain wheel, the hand chain hoist presses the friction plate ratchet and brake seat into one body and rotates together. The long tooth axis rotates the plate gear, short tooth axis and Spline hole gear. The lifting sprocket installed on the spline hole gear drives the lifting chain to lift the heavy object smoothly. The ratchet friction disc type one-way brake can brake on its own under load. The pawl engages with the ratchet under the action of the spring, and the brake works safely. As an upgraded version of the fixed pulley, the hand chain hoist completely inherits the advantages of the fixed pulley. At the same time, it adopts the combination of reverse backstop brake reducer and chain pulley block, and symmetrically arranges the two-stage spur gear rotation structure, which is simple, durable and efficient.
We should pay attention when using a hand chain hoist
Before use, check whether the sign of the hand chain hoist is consistent with the product to be lifted. The lifted items cannot exceed the rated lifting capacity of the sign.
When using a hand chain hoist, it cannot be operated with power other than human power, or multiple people can pull the chain together.
The lifting chain should be hung vertically, and there should be no wrongly twisted chain links. The lower hook of the double row chain cannot be turned over.
When pulling the chain, do not use too much force, but use even force.
If the operator finds that the pulling force is normal, he must stop using it and check it immediately.
