Electric hoist voltage: 110v, 220v, 240V, 380V, which is your electric hoist voltage?

01 Nov, 2016

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

  • The first category: 1 KV and above 1 KV voltage 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 voltage is called low pressure, such as 220 V, 230 V, 380 V, 415 V, 660 V;
  • The third category: below 50 V voltage is called safe voltage, such as 12 V, 24 V, 36 V, 48 V. So the hoist power supply voltage is low pressure and control voltage is safe voltage.

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 voltage fluctuation at the access point of the lifting machinery shall not exceed 5% of the rated value.cQ7Henan Dongqi Machinery Co., Ltd

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 voltage 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 voltage and frequency. The maximum safe voltage for human is 50 V. So the control voltage must be less than 50 V.cQ7Henan Dongqi Machinery Co., Ltd

The civilian voltage is single phase and the frequency is the same with industrial frequency. Usually the industrial voltage is 1.73 times the civilian voltage.cQ7Henan Dongqi Machinery Co., Ltd

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. cQ7Henan Dongqi Machinery Co., Ltd

Power supply fault and analysis

Fault Main cause Elimination methods
Press the button, the motor doesn’t work 1. Not connect to the power supplycQ7Henan Dongqi Machinery Co., Ltd
2. Lack of phasecQ7Henan Dongqi Machinery Co., Ltd
3. The power supply voltage is too low
1. Connect to the powercQ7Henan Dongqi Machinery Co., Ltd
2. Check main loop and control loopcQ7Henan Dongqi Machinery Co., Ltd
3. Adjust the power supply voltage
When Press the button, the motor start reluctantly and large noise, and it can't afford to load The power supply voltage is too low Adjust the power supply voltage
The hoist shell is charged or traveling motor has grunts 1. I steel off groundcQ7Henan Dongqi Machinery Co., Ltd
2. The electrical box shell off groundcQ7Henan Dongqi Machinery Co., Ltd
3. Motor or electrical devices have insulation damage
1. I steel groundingcQ7Henan Dongqi Machinery Co., Ltd
2. Check whether the beams tread has poor electrical conductivity things, should be clearedcQ7Henan Dongqi Machinery Co., Ltd
3. Check and repair the insulation damage location

When the motor voltage and frequency don’t match with power network voltage and frequency, the motor will be easy to burn. So if you want to buy a hoist, please tell us the correct voltage and frequency. Please also check our electric hoist products for different voltage. cQ7Henan Dongqi Machinery Co., Ltd
