    What should I do if the explosion-proof electric hoist fails?


Description: When using explosion-proof electric hoist for hoisting operation, sometimes the electric hoist will suddenly stop working. So what caused the explosion-proof electric hoist to stop working? Below is a summary There are several reasons: (1) First of all, we need to check whether the power supply voltage of the explosion-proof electric hoist is too low. If the voltage is too low to reach the operating speed, the grid voltage should be appropriately increased.
When using explosion-proof electric hoist for hoisting operation, sometimes the electric hoist will suddenly stop working. So what causes the explosion-proof electric hoist to not work? The following mountain hunting and carving crane equipment Co., Ltd. will give you a summary the reason:
(1) First of all, we must check whether the power supply voltage of the explosion-proof electric hoist is too low. If the voltage is too low to reach the operating speed, the grid voltage should be appropriately increased.
(2) Whether the power fuse is blown due to various reasons. If one phase is broken, the motor will start in a single phase, the starting torque is zero, and the motor cannot rotate, and sufficient fuses should be replaced.

(3) The load is too large. Generally, the explosion-proof electric hoist matches the power of the motor. The lifting weight cannot be overloaded. If the electric hoist cannot rotate, remove the load first. If the motor can start normally, it means that the transmission mechanism such as the reduction gearbox is faulty , Should check the dragged mechanism to clear the fault.
(4) Check whether the power supply system is supplying power to the explosion-proof electric hoist power supply. Generally use a test pencil to test. If there is no power supply, wait for power supply to work.
If the voltage used at the motor end of the explosion-proof electric hoist is more than 10% lower than the rated voltage, the starting torque of the motor is too small, so that the hoist cannot lift the goods and cannot work. When checking, use a voltmeter to measure the voltage at the motor input.
If your explosion-proof electric hoist fails, you can eliminate them one by one according to the above methods, then the problem should not be too big. More professional technical support questions about explosion-proof electric hoist, welcome to consult Liandu Lifting Co., Ltd !!
