    What to do if my Dunlop Lifting Systems lift is connected to the mains but doesn't work?
    • C
      Cheryl LaneAug 13, 2025
      If your Dunlop Lifting Systems lift is connected to the mains but isn't working, and the power indicator is off, there are several potential causes: * The transformer primary mains switch may be in the OFF position. If so, switch it to the ON position. * The emergency switch QM on the switchboard crankcase may be OFF. Switch it to the ON position. * The switch (QM) inside the electrical panel may be OFF. Try rearming the switch. * The power indicating lamp may be off, preventing control, or a three-phase equipment motor might have abnormal noise, indicating a lack of phase power. Check the voltage under the fuse base; if abnormal, replace the fuse.

      Roy CarrAug 21, 2025
      If your Dunlop Lifting Systems lift cannot completely lower, consider these possible causes: * A 10A fuse may be burned. Replace it with a new fuse. * The electromagnetic valve might not be opening completely. Adjust the installation position of the electromagnetic valve. * The stroke switch at the end of the chain protection device may not be working. Check the wiring of the stroke switch and wiring terminal to ensure they are correctly connected.

    What to do if my Dunlop Lifting Systems lift does not complete the lifting stroke?
    • T
      Tara WilliamsSep 5, 2025
      If your Dunlop Lifting Systems lift does not complete the lifting stroke, it could be due to several reasons: * The load may be exceeding the maximum flow rate. Check the maximum capacity of the lift. * The supply voltage may be too low. Check the supply voltage. * The oil level may be low. Fill the oil to the correct level.
