During the use of electric hoist, the causes of leakage:
1. The equipment interface is unqualified and there are wires missing
The power cord is not maintained, and the protection measures are not taken, so that the protector leakage, the line is chaotic, and the electric hoist connection wire is mixed with the wire connection of other equipment, resulting in complex lines, and sparks may occur in serious cases.
2. The working environment of the equipment is humid
In the same way that the power switch cannot be touched with wet hands, the motor is extremely prone to leakage in a very humid environment, which can lead to electric shock to the operator.
3. The power supply connected to the device is defective
Some users do not install the corresponding neutral line in accordance with national regulations when selecting the power supply, or the power supply is reversed, which is easy to leakage during use.
4. The power cord is damaged
The electric hoist works outdoors for a long time, coupled with the washing of rain and the exposure of the sun, each complete power cord is protected by an insulation layer on the outside, and no power cord is a conductor, and there will be leakage after the insulation layer is damaged, which is the most prone to leakage.
Electric hoist decoupling analysis:
The hook is one of the important parts in the lifting operation of the electric hoist, and the part that is in direct contact with the lifting goods is the most important, so the hook bundling work before the goods are lifted is very important.
If the bundle is not properly tied or the hook is not hooked, it is easy to dehook or slip in the process of lifting, which leads to the danger of falling goods, so it is necessary to be very careful when loading the hook.
