Electric hoist overload hazard

Views:41     Author:hengyuancrane     Publish Time: 24-01-2019      Origin:Site

As a special lifting equipment, the electric hoist is actually different from other electrical appliances. In terms of overload, we have seen many electric hoist precautions before. Many people will say that they must not overload using the outdoor electric hoist. What harm does the electric hoist overload using? Let's take a look!
The electric hoist is a lifting device installed on the electric overhead crane and gantry crane. The electric hoist has the characteristics of small size, light weight, simple operation and convenient use, and is used in industrial and mining enterprises, storage docks and other places. Electric hoist is mainly classified into electric chain hoist, wire rope electric hoist (explosion-proof hoist), anti-corrosion electric hoist, double-roll electric hoist and so on.
Anyone with a certain electrician base knows that if the motor is used excessively, it will cause an increase in current and a sudden increase in heat generation, resulting in insulation damage of the motor, which may directly burn the motor. Electric hoists as electrical appliances actually have the universality of electric motors.

There is data that half of the electric hoist accidents are caused by problems in operation, and the other half is overloaded with electric hoists. The most direct effect of overloading is the occurrence of wire rope breakage, which will directly lead to the rapid drop of the weight, resulting in the occurrence of unknown accident risk. Therefore, when using the electric hoist to work, pay attention to whether it is overloaded. Eliminate security risks and be responsible for the safety of yourself and others.
