The relationship between stage electric hoist and stage truss

　　Electric hoists used in factories, construction sites, bridge construction, and other occasions often need to be installed on I-beams and gantry cranes. As a lifting hoist used in entertainment occasions, stage electric hoists are not suitable for installation on industrial equipment such as I-beams and gantry cranes, but need to be installed on stage trusses. This not only improves the viewing effect of the stage, but also avoids personal injury to stage performers.

　　Stage trusses can be used to build stage backgrounds, lighting fixtures, etc. The material of the truss includes steel, aluminum alloy and other materials, and the structure includes square tubes, round tubes, etc. Regardless of the material and structure, lightweight and exquisite stage electric hoists can be installed on the truss to provide lifting services for stage performances. Its storage chain bag, appearance, cover, hook and other key parts are all designed in black, which will not affect the performance effect of the stage.

　　However, the stage electric hoist must rely on a power source to carry out lifting work. For situations where outdoor power is inconvenient to use, the stage chain hoist can be used for lifting work.

　　The lubricating oil of the stage electric hoist should be kept away from impurities

　　As is well known, the lubricating oil used to lubricate stage electric hoists must be kept clean in order to exert its true lubricating performance. Once impurities appear in the lubricating oil, it will have the opposite effect. So, first of all, we need to fully understand what factors can cause impurities in the lubricating oil of stage electric hoists?

　　Some staff members did not seal properly when using lubricating oil to lubricate the stage electric hoist, resulting in dust or debris penetrating into the interior of the stage electric hoist along with the lubricating oil. Alternatively, during the operation of the stage electric hoist, metal debris peeled off by the friction between components mixed into the lubricating oil, and these debris or solid particles infiltrated into the interior of the stage electric hoist along with the lubricating oil, accelerating the wear of its internal components.

　　So it is necessary to do a good job in sealing the stage electric hoist and regularly clean it to ensure the cleanliness of the lubricating oil.
