Electric chain hoist troubleshooting electric chain hoist is a very common use of tools, a lot of customers in the course of improper operation will cause many problems, the solution is as follows: 1, the original line phase electric wrong, resulting in phase protection action starts wholesale electric chain hoist, and therefore can not operate. The solution: two phases of the power cord swapped. 2, the power of the blown fuse or tripped fuse switch no. Solution: Check whether the current demand, replace the appropriate fuse or restart no fuse switch 3, the control circuit fuse burned. Solution: Check and replace the correct fuse. 4, the power cord or wire breakage or control circuit connected. Workaround: poor contact wire breakage and repair or replacement. 5, the power supply voltage is too low. Solution: measured voltage value is less than 10% of the standard supply voltage. 6, the motor sound, but did not rotate. Solution: Check the motor phases is correct - and good insulation repair action. 7, the emergency switch is pressed. Solution: Make sure that the cause of the emergency switch is pressed. 8, the contactor bad. Workaround: manually operated hoists, electric chain hoist if the normal action, the representative of the control coil or wire has poor contact - to find out the location of poor contact and repair; In terms of the operating manual chain hoist is still not operating, then need to check the main power supply is normal, if the main power is not a title, it is bad contacts, not the normal output, you need to replace the contactor. 9, the contactor coil shorted solution: replace the contactor Product Name: DHS rapid chain hoist Category: Electric Chain Hoist Product Description: DHS type fast electric chain hoist chain hoists lightweight and convenient to retain the characteristics, also improved manual chain hoists, lifting speed less 3t dhs chain hoist, electric hoist, and it sets the characteristics in a chain hoist, using disc brake motors powered chain hoist prices, planetary gear deceleration chain hoist, with a compact, small size, light weight, high efficiency, easy to use, reliable braking, easy maintenance features.
