The hazards of electric hoist overload
Electric hoist is a special lifting equipment, which is installed on overhead cranes and gantry cranes. 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 hoists are mainly classified into chain electric hoists, wire rope electric hoists (explosion-proof hoists), anticorrosive electric hoists, double-roller electric hoists, etc.
Anyone with a certain electrical foundation knows that if the motor is used at an excessive load, it will cause an increase in current and a sudden increase in heat generation, which will cause damage to the insulation of the motor and may directly burn the motor. Electric hoists as electrical appliances also have the continuity of electric motors.
The data show that half of the probability of electric hoist accidents is caused by operation problems, while the other half is overloaded with electric hoists. The most direct effect of overload is the situation where the wire rope breaks. This situation will directly lead to rapid weight Decline, causing unknown accident risks.
Therefore, during electric hoist using, pay attention to whether it is overloaded. Eliminate hidden dangers and take responsibility for the safety of yourself and others.
