Why is there a loss of hydraulic system power in my Gardner Denver Lifting Systems?

  If your Gardner Denver Lifting Systems experiences a loss of hydraulic system power, first ensure the emergency stop button is disengaged. Next, check that the power take off unit is fully engaged. If the problem persists, the geared power take off unit or the main hydraulic pump may have failed and require testing by replacement. Finally, verify that the relief valve isn't blowing off due to an incorrect pressure setting; if so, reset it to 190 Bar.

  Kayla DunnAug 18, 2025
  If the hydraulic oil in your Gardner Denver Lifting Systems is overheating, start by checking the hydraulic oil reservoir contents and replenish if low. If the issue continues, the main hydraulic pump might be worn. Connect a flow meter and pressure gauge to the pressure side of the hydraulic pump - the pump delivers approximately 8 liters/min at 190 Bar – renew if necessary. Also, check if the relief valve is blowing and reset it to 190 Bar if needed.

  If you're experiencing a complete electrical failure with your Gardner Denver Lifting Systems and there are no indicator lights at the stabilizer control panel, the first thing to check is the main input 40 Amp fuse under the dash. Then, inspect the PTO fuse 10 amp in the control panel (No6), followed by the panel fuse 25 amp in the control panel. Replace any blown fuses and investigate the cause of the failure.

  If the stabiliser legs of your Gardner Denver Lifting Systems creep upwards while operating the platform, this is likely due to lock valve leakage. Stop operating the platform as soon as possible, stow the stabilizers, and renew the malfunctioning lock valve cartridge. Do not operate the platform until the fault is rectified.
