110v, 220v, 240v, 380v electric chain hoist and electric rope hoist

 

The Volts level of the power network is divided into three categories.

  • The first category: 1 KV and above 1 KV Volts is called high pressure, such as 1 KV ,3 KV ,6 KV, 10 KV ,35 KV ,110 KV ,220 KV ,330 KV ,500 KV;
  • The second category: below 1 KV Volts is called low pressure, such as 220 V, 230 V, 380 V, 415 V, 660 V;
  • The third category: below 50 V Volts is called safe Volts, such as 12 V, 24 V, 36 V, 48 V. So the hoist power supply Volts is low pressure and control Volts is safe Volts.

The requirement of electric hoist power supply use 3P +PE power supply system (3P is Power supply wire, PE is ground wire), stressed to provide the ground wire, the track will not be used as a ground protection circuit. Under normal operating conditions, the Volts fluctuation at the access point of the lifting machinery shall not exceed 5% of the rated value.

In the power system of the world, there are two kinds of power frequency, one is 50 Hz, and the one is 60 Hz. Industrial Volts is different in each country, for example it is 3 phases, 380 V, 50 HZ in China, but in Philippines it 3 phases, 220 V ,60 HZ. Although both are located in Asia, and the distance is very close, but there is a great difference between the Volts and frequency. The maximum safe Volts for human is 50 V. So the control Volts must be less than 50 V.

The civilian electric hoist volts is single phase and the frequency is the same with industrial frequency. Usually the industrial Volts is 1.73 times the civilian Volts.

In use process, electric hoist is hard to avoid failure. In order to do well to the safe operation of electric hoist, timely and accurately process all kinds of faults has become an important part of construction production.

Power supply fault and analysis

FaultMain causeElimination methods
Press the button, the motor doesn’t work1. Not connect to the power supply
2. Lack of phase
3. The power supply Volts is too low
1. Connect to the power
2. Check main loop and control loop
3. Adjust the power supply Volts
When Press the button, the motor start reluctantly and large noise, and it can’t afford to loadThe power supply Volts is too lowAdjust the power supply Volts
The hoist shell is charged or traveling motor has grunts1. I steel off ground
2. The electrical box shell off ground
3. Motor or electrical devices have insulation damage
1. I steel grounding
2. Check whether the beams tread has poor electrical conductivity things, should be cleared
3. Check and repair the insulation damage location

When the motor Volts and frequency don’t match with power network Volts and frequency, the motor will be easy to burn. So if you want to buy a hoist, please tell us the correct Volts and frequency. Please also check our electric hoist products for different Volts.
