Electric wire rope hoist is a heavy lifting equipment with a wide range of uses, and is suitable for high-speed operation. It is durable, has a long operating cycle, and is relatively simple to maintain, but requires regular inspection and maintenance by personnel.In the use of wire rope electric hoist, the problem of size will be avoided during use. In order to avoid large and small problems in daily life, we must do it.
If the electric wire rope hoist fails abnormally, first cut off the power supply, unscrew the three screws on the support rod of the square end cover of the motor, and then unplug the motor end cover, take out the inner coupling of the drum, and check whether the coupling is not If it is worn out, use the circlip pliers to remove the bearing positioning circlip in the reel, turn up the reducer case body upwards, use a suitable iron rod against the long shaft of the box body, punch lightly, punch down the long shaft, and check Whether the long shaft or bearing is damaged, if it is damaged, it should be replaced with a new one, and then the crowbar can be separated from the side plate to disassemble it.
Check whether the gear and bearing are worn, and then reinstall it after replacing the new one.What is the reason for the abnormal operation of the CD-1 type wire rope electric hoist motor or a humming sound?If the brake is too tight or locked, adjust the brake clearance in time, and check whether the power supply or the junction box is in good contact in time if a certain phase of the power supply is cut off.
When the electric hoist is no-load, the motor does not start or the reel does not turn when the motor turns?
