The 500kg mini electric hoist is an electric hoist that can be used on a small hoist. The lifting and lowering are controlled by wired remote control. If there is a lot of abnormal noise during use, it must be repaired in time.
Mini crane maintenance electric hoist running abnormal sound:
1, Abnormal noise occurs in the control loop, and a “hum” noise is emitted. Generally, the contactor of the miniature electric hoist is faulty (such as poor contact of the AC contactor, inconsistent voltage levels, stuck magnetic core, etc.). The faulty contactor needs to be repaired. If it cannot be repaired, it must be replaced. After treatment, the noise will be eliminated by itself.
2, If the motor makes abnormal noise, it should be stopped immediately to check whether the motor is running in a single phase, or if the bearing is damaged, the shaft center of the coupling is not correct, and the “sweeping” and other faults will cause the motor to make abnormal noise. The pitch and tone are different. During single-phase operation, the entire motor emits a regular “humming” sound that fluctuates stronger and then weaker; and when the bearing is damaged, a “humming” sound accompanied by “clack-clack” will be issued near the bearing. ; And when the shaft center of the coupling is not aligned, or the motor is slightly swept, the entire motor emits a very high “humming” sound, accompanied by a sharp and harsh sound from time to time.
3, Abnormal noise is emitted from the reducer, and the reducer is faulty (such as lack of lubricating oil in the reducer or bearing, gear wear or damage, bearing damage, etc.), then it should be stopped for inspection.
