Moisture can affect the performance of lubricating oil for stage electric hoists

　　In order to ensure its efficiency and performance, stage electric hoists cannot do without lubricating oil. It can not only reduce the friction of components and protect their lubrication, but also play a role in cooling, rust prevention, sealing, etc. It can be said to be the "golden oil" of stage electric hoists. Why should the lubricating oil of the stage electric hoist be kept away from damp or humid environments as much as possible during use?

　　After the lubricating oil contains moisture, it will weaken the strength of the lubricating oil film, reduce the lubrication function, and cause rusting and corrosion of the metal parts of the stage electric hoist. Moisture will also cause the lubricating oil to deteriorate, and even the deteriorated lubricating oil will produce acidic substances, causing corrosion to the stage electric hoist.

　　From this, it can be seen that moisture can affect the performance of lubricating oil for stage electric hoists, causing a decrease in the performance of the lubricating oil and thus affecting the stage electric hoist. Therefore, it is necessary to stay away from damp and humid working environments as much as possible.

　　How to detect problems from the static and working states of the stage electric hoist

　　The stage electric hoist plays a crucial role in the process of theater performances. It has a remote control function, and the lifting and lowering of heavy objects can be remotely achieved by controlling the lifting buttons on the handle, thus avoiding the adverse effects of personnel manually pulling the chain and walking back and forth on the stage on the stage performance.

　　For stage electric hoists, daily maintenance and management work is quite important. Only by maintaining excellent performance can they smoothly perform their functions during performances. However, with the increase of equipment usage time and frequency, various aging and malfunction problems may occur in the internal components of the electric hoist, which is not conducive to the stable lifting operation of the electric hoist.

　　When the stage electric hoist is in a stationary state or non working state, we can judge its fault condition by observing its appearance, such as checking whether the hook and chain have cracks, rust, corrosion, etc., whether the stabilizing tongue can smoothly clamp the heavy object, and whether the cover has good protective function.

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