What to do if the Skyjack Lifting Systems generator is not rotating?
If the generator isn't rotating, the issue might stem from a motor that won't turn, a faulty directional valve, or a broken drive key. You should: * Check for proper hydraulic flow. * Check the voltage to the coil. * Check and replace a bad coil or valve.
Why is the frequency falling under load on my Skyjack Lifting Systems generator?
If the generator's frequency drops when under load, it could be due to the hydraulic flow to the motor falling or a bad motor. Ensure the flow to the motor is constant, and if the problem persists, consider replacing the motor.
What to do if my Skyjack Lifting Systems generator has proper no-load but low loaded voltage?
If your generator shows the correct voltage without a load but low voltage when loaded, the issue might be due to low speed when loaded, an excessive load, or short-circuited diodes. You should check and adjust the RPM, check and repair the excessive load, and check and replace any short-circuited diodes.
Why is my Skyjack Lifting Systems generator noisy?
A noisy generator may be caused by broken bearings or poor coupling. Replace the bearings or check and repair the coupling.
What causes unstable voltage in Skyjack Lifting Systems?
Unstable voltage can result from poor contacts or uneven rotation. Check the connections and ensure uniform rotation speed.
What causes high no-load voltage in Skyjack Lifting Systems?
High no-load voltage is often caused by excessive speed or a high capacity capacitor. You should check and adjust the speed, and check and replace the capacitor.
What to do if Skyjack Lifting Systems has proper voltage in no-load conditions but high voltage at load?
If you observe proper voltage without a load but high voltage when loaded, the cause might be high speed in the loaded condition. Check and adjust the speed to resolve this issue.
Why does the Skyjack Lifting Systems generator not excite?
If the generator fails to excite, potential causes include low speed, a faulty capacitor, or a breakdown in the windings. Check and adjust the speed, check and replace the capacitor, and check the winding resistance.
Why does my Skyjack Lifting Systems have low no-load voltage?
Low no-load voltage can be attributed to several factors: low speed, faulty rotary diodes, worn windings or low capacity of the capacitor. To address this, check and adjust the RPM, check and replace the faulty rotary diodes, check the winding resistance, and check and replace the capacitor.
