The use of wire rope hoist used in factories, mines, docks, warehouses, garages and other working conditions, temperature -20 ~ + 40 ℃, relative humidity less than 85% of the establishments. In hazardous places full of sulfuric acid or other corrosive gases and molten metal being lifted, toxic, flammable materials are prohibited to use in place to ensure safety. Severe or open spaces in the dust when used, need to add protection. Electric wire rope hoist brake failure reasons for using wire rope hoist friends must have encountered wire rope hoist brake failure phenomenon will decline even more eye makeup hook, this situation must be treated with caution, otherwise it would be construction who lives a serious security threat, we understand the strong today with wire rope hoist brake failure causes, and solutions. We think the reason is the failure of electric wire rope hoist, conical rotor under the action of the electromagnetic force, in addition to a rotating movement, the same time when the motor is energized to produce an axial force to the right spot wire rope hoist, the shaft to the right. Electric wire rope hoist motor spindle taper right end of the motor and the brake ring a cover 3 disengagement, while the spring on the spindle motor 2 is compressed, the normal rotation motor, driven by the coupling and drum rotation speed reduction mechanism, so that the weight lifting . When the power is turned off, the electromagnetic force disappears, the rotor shaft by the compression spring to the left to force member 1 and the member 3 again has a certain pressure securement, rapid braking of the rotor, such a cycle, the vibration difference large. Although spring lock washer, but due to the frequent under severe shock, vibration, screws also smaller, resulting in a period of time after the wholesale electric wire rope hoist, constantly loose pieces 3 pieces until 5 left in contact with, which prevents member 5 in downtime When normal axial leftward movement, so that after the right end of the brake ring member 5 snapping force of the motor is reduced and the breakdown between the end cap, the hooks will be no load serious decline themselves.
