The electric hoist is a multifunctional lifting equipment, which can be used with pulley rails, cantilever suspension brackets, supporting brackets, lifting strap accessories, etc. to achieve vertical lifting, lowering, lateral movement and rotation. It is suitable for various occasions and has a small size. High efficiency and high safety performance. The lifter relieves the labor pain of lifting the shoulders, but when using an electric lifter to lift, sometimes the lifter generates heat and is weak to make noise. So what is the reason?
* After the motor is wound, the noise is high after the power is turned on. Normal start is a large bearing clearance.
Second, the motor cannot start or the speed is slow, because the head and tail of the three-phase winding (capacitor) are connected incorrectly.
Third, the motor is unable to heat up quickly, which may be an extremely indirect method error.
Fourth, the hoisted cargo has reached the limit working load of the motor, and even the motor is overloaded.
Fifth, the inside of the motor may be soaked with rain and the symptoms before burning.
Sixth, the hoist wire rope may have uneven winding, chaos and twisted rope.
The combination of the above 6 phenomena will cause the hoist to generate heat or generate noise during work. In the process of lifting articles, once the electric hoist is found to be hot, unable to lift, and "squeak", the operator should immediately cut off the power and put the goods down as smoothly as possible through the clutch under controllable conditions. Check the causes in 6 cases. If you need technical service, you can consult the multi-functional elevator manufacturer. The hoist belongs to precision electrical equipment. Once the equipment is damaged, it is forbidden to dismantle it without permission. During the warranty period, you can consult the relevant personnel of the manufacturer or the anti-factory repair.
