How to prevent lubricating oil from dripping onto the stage electric hoist chain

　　The stage electric hoist is a small lifting tool specifically designed for lifting stage performance equipment above the stage. With its participation, we are fortunate to see the colorful stage effects and feel the professional sound effects. Compared with other electric hoists, the stage hoist is not only responsible for its own job: lifting tasks, but also for the performers and performance effects on stage.

　　Most stage electric hoists use chains as lifting mechanisms. Although chains have strong load-bearing capacity and wear resistance, they must be properly lubricated and maintained after long-term use to improve their smoothness.

　　To do lubrication and maintenance work on the chain, lubricating oil needs to be applied to the chain. Lubricating oil is liquid, and if it is not air dried in time after application, it will be hung and used. The lubricating oil on the chain will drip onto the ground and stage.

　　The chain must be galvanized and lubricated to be smoother. To prevent grease from dripping, we can install lubricating grease in the gearbox to prevent oil droplets from penetrating the stage.

　　Why do stage electric hoists use chain type instead of steel wire rope type

　　The stage electric hoist is a branch of the chain electric hoist, which is an important lifting equipment used for stage construction and lighting position adjustment. Some people have questioned why stage electric hoists are all chain type and do not use steel wire ropes

　　Firstly, the stage electric hoist needs to have a certain degree of concealment, including color and volume. If the volume of the stage electric hoist is large, it will definitely affect the stage effect. Generally, in terms of volume, the steel wire rope electric hoist is much larger than the same specification ring chain electric hoist, and some may even be more than ten times larger.

　　Next, in terms of lifting accuracy, due to the arrangement of the rigging on the drum, as the wire rope winds around the drum, the lifting target of the wire rope electric hoist will also experience horizontal displacement. The higher the lifting height, the greater the displacement. The hook of the electric chain hoist always rises vertically along the chain, which can achieve precise positioning.

　　During the construction process of the stage electric hoist, attention is paid to the accuracy of the lifting position, and the stage effect is also emphasized after completion. Therefore, the stage electric hoist will use a chain type electric hoist.
