How to judge the quality of stage electric hoists?

　　Nowadays, consumers are becoming increasingly rational and have basically bid farewell to impulsive consumption. Many people are starting to pursue buying the right things, not just the expensive ones. The same applies to mechanical products, especially in different construction scenarios and working environments, where it is important to choose high-quality products based on actual conditions. As a specialized lifting equipment for stage construction, the stage electric hoist is also the same. So how can we choose the right stage electric hoist?

　　One is that the nameplate is clear. The nameplate of the stage electric hoist contains a lot of information, including manufacturer information, rated load capacity, maximum load capacity, lifting height, etc., which should be clearly visible and meet the customer's purchasing needs

　　The second is the safety and stability of the stage electric hoist motor. The motor is the core of the stage electric hoist and can be tested first to ensure that there are no abnormal phenomena such as high temperature and noise

　　Thirdly, it depends on the workmanship of the stage electric hoist. The surface is smooth, without any dents or burrs. A stage electric hoist with even and delicate spray paint will be more reassuring.

　　You can judge the quality of the stage electric hoist by the above points to ensure that you have purchased the right product.

　　Frequent malfunctions of stage electric hoists

　　As a mechanical equipment, stage electric hoists inevitably encounter problems and malfunctions during service. The problems that occur with each stage electric hoist are also different, but they all affect normal production operations. So, what are the common problems with stage electric hoists?

　　One is the abnormality of the motor. The main power source of the stage electric hoist is the motor, which may cause noise, bearing damage, motor phase loss, motor overheating, and inability to drive heavy objects;

　　The second issue is that the electric hoist on stage cannot stop or stop the vehicle, which may be due to a malfunction in the braking system of the electric hoist, such as severe wear on the braking ring, reduced spring pressure causing a decrease in braking force or failure of the limiter, and the motor still running, causing the electric hoist on stage to be unable to stop;

　　Thirdly, the components of the stage electric hoist are excessively worn or fatigued during operation, resulting in reduced strength and the occurrence of broken hooks or chains.

　　The above are the common problems and malfunctions of stage electric hoists. After these problems occur, they should be repaired according to the actual situation. If the damage is very serious, it should be treated as scrap.
