Safe operation methods for stage chain hoists

　　1. Overloading with diagonal braces is strictly prohibited. It is strictly prohibited to operate with power other than human labor.

　　2. Before use, it is necessary to confirm that the components are intact, the transmission parts and lifting chains are well lubricated, and the idle condition is normal. Before lifting, check if the upper and lower hooks are securely fastened. The lifting chain should be hung vertically without any twisted links, and the lower hook frame of the double chain should not be flipped over.

　　3. The operator should stand in the same plane as the hand chain wheel and pull the hand chain, causing the hand chain wheel to rotate clockwise to lift the heavy object; Pull the hand chain in reverse to slowly lower the heavy object. When lifting heavy objects, it is strictly prohibited for personnel to do any work or walking under the heavy objects to avoid major accidents.

　　4. During the lifting process, regardless of whether the heavy object rises or falls, when pulling the hand chain, the force should be evenly and gently applied, and excessive force should be avoided to prevent the hand chain from jumping or getting stuck.

　　5. If the operator finds that the hand tension is greater than the normal tension, they should immediately stop using it. Prevent damage to internal structure to prevent falling object accidents. After the heavy object lands safely and steadily, remove the hook from the chain hoist.

　　6. After use, handle with care and place in a dry and well ventilated place. Apply lubricating oil and place properly.

　　Maintenance steps for stage chain hoist

　　1. By conducting no-load experiments, observations, and other methods, check whether there are any abnormal conditions in the components of the chain hoist. If so, please repair or replace them in a timely manner;

　　2. The specialized cleaning agent for experimental stage chain hoists cleans all the oil stains on the surface of the hoist, especially the dead corners of components such as chain links and covers;

　　3. Use a dry cloth to wipe off the dissolved oil and water vapor on the surface of the stage hoist;

　　4. Apply rust proof grease to the surface of the easily corroded components of the stage chain hoist, apply lubricating grease to the surface of the frequently rotated components, and let them stand for a period of time until the grease is absorbed;

　　5. Pack the stage hoist in a wooden box and store it in a cool, dry place for sealing.
