Hand-Pulled Hoist Usage Rules:

1. Strictly prohibited overloading.
2. It is strictly prohibited to operate with any power other than human.
3. Before use, ensure that the machinery is undamaged, the transmission parts and hoisting chains are well lubricated, and the empty rotation is normal.
4. Before hoisting, check if the hoists at the top and bottom are securely attached. It is strictly prohibited to hoist heavy objects at the tip or engage in other incorrect operations. The hoisting chain should be hung vertically, and there should be no misaligned link rings. The lower hoist frame of the double-row chain should not be reversed.
5. The operator should stand on the same plane as the bracelet wheel and pull the hand chain to make the bracelet wheel rotate clockwise, which can make the weight rise; reverse the hand chain, and the weight can slowly descend.
6. When hoisting heavy objects, it is strictly prohibited for anyone to perform any work or walk under the heavy objects to prevent any personal injuries.
7. During the hoisting process, whether the heavy object is rising or falling, when pulling the hand chain, the force should be even and gentle, do not apply too much force, to avoid the hand chain jumping or getting stuck in the ring.

8. If the operator finds that the pulling force is greater than the normal force, they should immediately stop using the device.

Hand-crank hoist maintenance method:
1. After use, the gourd should be cleaned thoroughly and coated with anti-rust grease, then stored in a dry place.
8. Maintenance and inspection should be performed by individuals familiar with the crane mechanism to prevent individuals unfamiliar with the machine's performance principles from disassembling and assembling it at will.
3. After cleaning and repairing the gourd, it should undergo an empty-load test to confirm that the operation is normal and the braking is reliable. Only then can it be delivered for use.

4. The friction surface of the brake must be kept clean. The brake parts should be regularly inspected to prevent brake failure and the occurrence of objects falling spontaneously.
