Electric chain hoist is a hoist, which is a relatively compact structure, light weight, small size and operational aspects of the lifting equipment. Electric wire rope hoist parts commonality is very strong, can be used alone to install and use, but also with other lifting equipments. Currently, the wire rope hoist is widely used in construction, factories, roads, bridges, electricity, shipbuilding and other industries. Especially in the past decade, the rapid development of China's construction industry, greatly enhance the demand for wire rope hoist. Chain hoist troubleshooting methods using lifting equipment when direct electric chain hoist, will inevitably encounter some problems, the quality of electric chain hoist, chain hoist Take an example to explain it, he said He said chain hoist can not turn and start solutions at work now. First of all: to see the power fuse is not burned out, and if we find the starting torque is zero, the motor can rotate lifting accessories, electric chain hoist supply should be sufficient to replace the fuse. Second: the voltage problems, many electric hoist will encounter this problem, so when buying electric hoist to a voltage to buy their own products. Then: stator winding phase short circuit, earth or open circuit, you should check the equipment wiring issue, but it should also check the core and pull off, with or without card phenomenon, if necessary, replace the contactor. Last: simply look at the problem is not overloaded, if we find the electric motors, it shows the gearbox and other transmission mechanism is defective should be timely inspection. Each electric hoist, electric chain hoist, Liaoning, basically related to these aspects, want to be able to provide some help, summarized above, are for reference only.
