The principle of three prohibitions for the use of stage chain electric hoists

　　The use of stage chain electric hoists is also allowed or not allowed. Today, the editor will introduce the three no allow principles for its use, hoping to be helpful to you.

　　Not allowed to work in the rain: one is to prevent rainwater from entering the interior of the motor and causing short circuit faults; Secondly, it is to prevent rainwater from causing certain corrosive effects on its components.

　　No two, not firmly fixed: Whether it is fixing an electric hoist or a heavy object, it must be firmly fixed, after all, the person standing under the suspended object is human. Once a heavy object falls, the consequences can be unimaginable.

　　Do not overload lifting: After all, the heavy objects lifted by the electric hoist are in a long-term suspended state. If overloaded, the impact on its components will be very serious, so special attention should be paid.

　　For the safety of operating the stage chain electric hoist, I hope you will not engage in the three prohibited operations mentioned above, okay?

　　What are the "symptoms" of the stage electric hoist car gnawing on the track?

　　As the name suggests, the stage electric hoist car gnaws on the track, which means that the car gets stuck with the track, causing wear and tear between the car and the track. If not detected and resolved in a timely manner, it is likely to cause fatal injuries to the car and track. But many people cannot detect the phenomenon of rail gnawing in a timely manner, and only realize it when the problem is serious. However, at this point, the damage is already irreparable. So how can we avoid this problem? Today, the editor will teach you how to identify a small car gnawing on the track.

　　Firstly, there is a slight gnawing of the track by the small car, and one can vaguely feel that the pushing of the car is not very smooth, accompanied by subtle left and right shaking of the car.

　　Secondly, the moderate small car gnaws on the track, making a lot of noise at the beginning and end of the pushing process. There is a noticeable sense of obstruction during the pushing process, and the small car shakes more, causing the heavy object to tilt or swing accordingly.

　　Thirdly, the moderate car gnaws on the track, and the wear and scratches between the car and the track are clear, with a gap of over 6 centimeters between the two.

　　Fourthly, the extreme car gnaws on the track, causing a sharp and piercing sound when starting. The gap between the car and the track (at either end) is close to 10mm (greater than 10mm may cause the car wheels to detach from the track and fall)

　　The above is the "growth" process of the stage electric hoist car gnawing on the track. Stage workers must pay attention to whether any accidents occur when using a small car, and if so, promptly nip the danger in the bud.
