Five characteristics of explosion-proof chain hoist

Oct 19, 2021

1. Higher safety performance

Explosion-proof chain hoist has increased the explosion-proof function compared to the ordinary chain. It can effectively ensure the safety of the equipment when it is used, and the structure has also been comprehensively designed. It's more convenient to carry, improves its seismic performance and and the operation flexibility is stronger.

2. Improve efficiency

Compared with the ordinary chain hoist, the lifting speed of the explosion-proof hoist is faster, and the lifting capacity has been correspondingly improved. The explosion-proof hoist adopts a 2-stage gear design, which can effectively avoid overloading of lifting goods. The high-strength lifting chain also makes the operation of the equipment more stable.

3. Check the voltage

We need to check the operating voltage to ensure that the voltage value is not less than 10% of the rated voltage. Because the motor needs a too small torque range when it starts to start, it needs to consume a lot of electricity to be able to lift goods. So sometimes the voltage is too low to cause the equipment to fail to start normally. When checking the equipment voltage, we can use a multi-meter and other measuring instruments to measure the relevant voltage value, but to ensure the stability of the equipment voltage.

4. Check if there is a missing phase

Short circuit and open circuit in the line will also cause insufficient power supply for the equipment, making the chain hoist equipment unable to operate normally. For this kind of failure, we need to conduct a detailed inspection of the circuit board of the device. When inspecting the circuit board, it is necessary to cut off the power supply. Otherwise it will not only cause damage to the circuit board, but also threaten the safety of human life.

5. Check the power-off situation

After completing all the above steps, we need to check the power on of the equipment. Under normal circumstances, you can use a test pen to measure, and repair the lines that cannot be connected in time.
