How to identify problems from the static and working states of stage chain electric hoists

　　The stage chain electric hoist plays a crucial role in the performance process of the theater. It has a remote control function, and the lifting button on the control handle can remotely achieve the lifting and lowering operation of heavy objects, thereby avoiding the adverse effects of manual pulling of the chain and walking back and forth on the stage on the performance effect.

　　For the stage chain electric hoist, daily maintenance and management are very important. Only by maintaining excellent performance can it smoothly perform its functions during the performance. However, with the increase of equipment usage time and frequency, various aging and malfunction problems will occur in the internal components of the chain electric hoist, which is not conducive to the safe lifting operation of the electric hoist.

　　When the stage chain electric hoist is in a stationary or non working state, we can determine its malfunction by observing its appearance, such as observing whether the hook and chain have cracks, rust, corrosion, etc., whether the safety tongue can smoothly catch heavy objects, and whether the cover has good protective functions.

　　When the stage chain electric hoist is in normal working condition, we can analyze its fault situation through factors such as abnormal noise, running speed, frequency, etc.

　　What should I do if the stage electric hoist suddenly stops working

　　The stage electric hoist is a specialized lifting device designed and produced specifically for the construction of drama, concert, and variety show stages. If it suddenly stops working, we don't need to panic, just patiently identify the fault and repair it.

　　Firstly, the areas that need to be inspected include:

　　1. Power supply for electric hoists. The equipment on stage is chaotic, with a large flow of people and numerous circuits. During the performance, the performers or onlookers may touch the power socket, causing poor power contact or directly interrupting the power supply, resulting in the inability of the electric hoist to function properly.

　　2. The voltage of the power supply. Electric hoists can only lift heavy objects normally at the rated voltage of 220V or 380V. If the current voltage is too low, it will not be able to provide sufficient power for the motor.

　　If there is no problem with the power supply, technical personnel need to quickly replace other electric hoists of the same specification and model. After the performance is over, time will be arranged to repair the damaged electric hoists.

　　So in order to avoid the sudden malfunction of the stage electric hoist during the performance, on-site staff should inspect the equipment in advance and always ensure the protection of cables and wires during the performance.
