Troubleshooting guide for stage chain hoist: Ensure smooth performance

　　In the wonderful presentation of stage performance, the stage hand gourd plays an indispensable role. However, sometimes the chain hoist may have some malfunctions that can affect the smooth progress of the performance. Below are some common troubleshooting methods for stage chain hoists.

　　1、 Chain lag

　　Check if the chain is twisted or tangled. If the chain is found to be twisted or tangled, it should be carefully straightened to ensure that the chain can run smoothly.

　　Check if there are any foreign objects stuck in the chain. Sometimes, small particles, dust, or debris may enter the chain, causing it to jam. Use a clean cloth or brush to clean any foreign objects on the chain.

　　Check whether the sprocket is worn or damaged. If the sprocket is severely worn, it may cause poor meshing between the chain and sprocket, leading to jamming. In this case, it is necessary to replace the sprocket.

　　2、 Pulling the handle is laborious

　　Check if the chain is too tight. If the chain is too tight, it will increase the resistance to pulling the handle. The chain can be relaxed appropriately to maintain a suitable tension state.

　　Check whether the mechanical components inside the chain hoist are rusted or stuck. If there is rust or jamming, lubricating oil can be used to lubricate the chain block to reduce frictional resistance.

　　Confirm if the load exceeds the rated load of the chain hoist. If the load is too heavy, it will make pulling the handle very difficult. When using a chain hoist, be sure to ensure that the load is within its rated load range.

　　3、 The hook cannot open and close normally

　　Check if the spring of the hook is damaged. If the spring is damaged, the hook may not be able to open and close properly. A new spring needs to be replaced.

　　Check if there are any foreign objects blocking the lock catch of the hook. Sometimes, small particles or debris may enter the lock, causing the hook to fail to open and close properly. Clean the foreign objects in the lock buckle to ensure smooth operation.

　　Check if the structure of the hook is deformed. If the hook is impacted or excessively stretched by external forces during use, it may cause structural deformation. In this case, it is necessary to replace the hook.

　　4、 Hand pulled hoist cannot lift heavy objects

　　Firstly, confirm whether the chain hoist is installed correctly. Check if the installation position is secure and if the chain is correctly connected to the hook and heavy object.

　　Check if the load exceeds the rated load of the chain hoist. If the rated load is exceeded, the chain hoist may not be able to lift heavy objects.

　　Check if the internal mechanical structure of the chain hoist is damaged. For example, whether components such as gears and shafts are worn or broken. If mechanical structure damage is found, it needs to be repaired or replaced in a timely manner.

　　5、 Safety precautions

　　When troubleshooting, be sure to ensure that the stage hoist is in a safe state. Avoid maintenance under load to prevent accidents.

　　If you are unsure about troubleshooting, it is best to seek the help of professionals. They have rich experience and professional knowledge, which enables them to more accurately determine the cause of faults and carry out repairs.

　　Regularly maintain and inspect the chain hoist to prevent malfunctions from occurring. Keep the chain hoist clean, apply lubricating oil regularly, and check the wear of components such as chains and hooks.

　　In short, stage gourds play an important role in stage performances. Timely troubleshooting is the key to ensuring the smooth progress of the performance when a malfunction occurs. Through the above methods, we hope to help everyone quickly and effectively solve the problem of stage chain hoist malfunctions.
