      If the motor of your Unicraft Chain Hoists isn't working, there are several potential causes. It could be due to an inadequate power supply, so you should check the power supply first. Other possible causes include a wrong phase conductor (change the phase), a defective switch (replace the switch), a defective rectifier (replace the rectifier), a defective transformer (replace the transformer), or a defective motor (change the motor).

      David Johnson MDAug 16, 2025
      Leakage current in your Unicraft Chain Hoists can stem from several issues. Check the earthing or make a connection, as poor or no earthing could be the cause. Also, inspect the cables, because interior cables might be in contact with the casing. High humidity can also lead to leakage current, so avoid working when the humidity is too high. Finally, ensure that the appliance parts are clean, as dirty live components can cause this issue.
