Why choose light duty gantry crane?

For the cost, light small crane is much cheaper than heavy duty large crane. Small crane has less maintenance and cost less.
The reason of electric motor’s phase-lacking
First, the contacting point of the contactor starts frequently and burns out. The deformation of contacting plate spring and contacting plastic can lead contacting point incorrect position and cause phase-lacking.
Second, the fuse is too small, the temperature is too high, these two factors cause the fuse burned out and phase-lacking.
Third, power supply has poor contact.
Fourth, motor-in line has bad contact.
If motor’s phase-lacking occurs, what to do? Install automatic switch with highly sensitive, thermal over-current protector and phase-lack protector.
Except for motor’s phase-lacking, there are other reasons why electric motor burns out. First is overload, second, the crane shaft is damaged, third, the brake can’t work well.
