Stage hand pulled gourd: daily maintenance and upkeep

　　The stage gourd is like an unknown hero behind the stage, and daily maintenance and upkeep are crucial to ensure its continuous, efficient, and safe service to the stage performance.

　　1、 Pre use inspection

　　Shell integrity

　　Before each use, carefully inspect the outer shell of the chain hoist. The shell should have no obvious collision marks, deformation or cracks. Any minor damage to the outer shell can affect the stability of internal mechanical components and even lead to safety accidents.

　　Hook safety

　　Focus on checking the wear of the hook. The hook body of the hook should have no obvious wear grooves, and the hook tip should not be deformed or cracked. At the same time, check whether the anti detachment device of the hook is intact to ensure that the heavy object will not accidentally fall off during the lifting process.

　　Chain quality

　　The chain is one of the core components of a chain hoist. Check if the chain links are twisted, deformed, or severely worn. You can manually pull the chain to feel if it is smooth and if there is any jamming. The lubrication status of the chain cannot be ignored, as good lubrication can reduce the wear of the chain.

　　2、 Precautions during use

　　Standardize operational techniques

　　The operator must be proficient in the operation method of the chain hoist. When pulling the handle, maintain a steady and uniform motion to avoid sudden excessive force or sudden stop. This not only ensures the smoothness of the lifting process, but also reduces the impact force on the internal structure of the hoist.

　　Strictly control the load

　　Clearly define the rated load of the chain hoist and strictly adhere to it. Before lifting heavy objects, it is necessary to accurately estimate the weight of the object to ensure that it does not exceed the carrying capacity of the hoist. Overloading can cause excessive stress on components such as chains and hooks, which can easily lead to component damage.

　　3、 Maintenance details after use

　　The cleaning work should be in place

　　After the performance, clean the chain hoist in a timely manner. Wipe the outer shell with a clean cloth to remove dust and oil stains. For chains, a specialized chain cleaner can be used to clean them, remove dirt, and then dry them with a dry cloth.

　　Reasonable lubrication is essential

　　Lubrication is a crucial step in maintaining a chain hoist. Choose lubricating oil suitable for the chain and apply it evenly on the chain. Be careful not to apply too much to avoid lubricating oil dripping onto the stage and causing pollution. At the same time, other moving parts of the gourd, such as gears, bearings, etc., should also be lubricated appropriately.

　　Proper storage is crucial

　　When the chain hoist is not in use, it should be stored in a dry and ventilated place. Avoid storing in damp, high-temperature, or corrosive environments. Before storage, ensure that the chain is in a relaxed state to avoid fatigue caused by prolonged tension.

　　4、 Regular inspection and professional maintenance

　　Regular comprehensive inspection

　　Regularly conduct a comprehensive inspection of the hand pulled gourd. In addition to inspecting the casing, hooks, and chains, internal components such as gears and braking devices should also be checked. Check whether the gears are worn and whether the tooth surface is smooth; Whether the braking device is sensitive and reliable.

　　Professional maintenance and timely follow-up

　　If a malfunction or damage is found in the chain hoist during inspection, professional maintenance personnel should be contacted promptly for repair. Do not disassemble or repair on your own to avoid causing more serious damage.
