Common hydraulic lifting equipment issues and effective troubleshooting tips

Hydraulic lifting equipment plays a vital role in many industries, from construction to manufacturing, transport, and logistics. However, like any other type of machinery, they can encounter problems during operation. Understanding these issues not only ensures hydraulic lifting equipment safety for people and goods but also avoids operational disruptions. Let’s explore common hydraulic lifting equipment issues and simple, effective troubleshooting tips.

Common Hydraulic Lifting Equipment Issues

Hydraulic Oil Leakage

• Causes: Damaged seals, gaskets, hoses, or worn and loose cylinders.
• Consequences: Reduced work efficiency, environmental pollution, and even risks of fire or explosion.

Unstable Hydraulic Cylinder Operation

• Causes: Contaminated hydraulic oil, air in the system, or jammed/damaged control valves.
• Consequences: The lifting device jerks, shakes, or fails to lift accurately, endangering operators and cargo.

Inefficient Hydraulic Pump

• Causes: Worn or damaged pump, insufficient oil viscosity, or clogged oil filters.
• Consequences: The lifting device operates weakly, sluggishly, and consumes more energy.

Overheating

• Causes: Overloading, inadequate cooling of hydraulic oil, or system leaks.
• Consequences: Reduced hydraulic oil lifespan, damaged seals and gaskets, and fire hazards.

Abnormal Noise

• Causes: Worn hydraulic pump, jammed control valves, or loose components.
• Consequences: Causes discomfort for operators and serves as a warning of equipment failure.

Other Issues

• Electrical control system failure.
• Hydraulic brake failure.
• Reduced hydraulic pressure.
• Loss of lifting capability.

Guide to Troubleshooting Hydraulic Lifting Equipment During Operation

Equipped with the knowledge and skills to handle hydraulic lifting equipment failures, you can minimize damage and ensure safety for yourself and those around you.

Below is a guide on how to handle some common issues:

Hydraulic Oil Leakage

• Locate the leak: Carefully inspect pipes, joints, and cylinders to find the source.
• Stop equipment operation: Immediately stop the device upon detecting a leak to prevent further damage.
• Temporary fix: If possible, use tape or suitable materials to temporarily plug the leak.
• Notify the maintenance department: Contact maintenance for repair support.

Unstable Hydraulic Cylinder Operation

• Check hydraulic oil levels: Ensure the oil is at the correct level and free from contamination.
• Bleed air from the system: Perform air bleeding according to the manufacturer’s instructions.
• Inspect control valves: Check if valves are jammed or damaged. Replace if necessary.

Inefficient Hydraulic Pump

• Check hydraulic oil: Ensure the oil has the correct viscosity and is clean.
• Check the oil filter: Clean or replace the filter if it is clogged.
• Inspect the pump: If the pump is faulty, it needs to be replaced.

Overheating

• Reduce load: If the equipment is overloaded, reduce the weight immediately.
• Check the cooling system: Ensure the cooling system is functioning correctly.
• Give the equipment a break: If it has been running continuously for a long time, let it rest to cool down.

Abnormal Noise

• Inspect components: Identify the source of the noise and check related parts like the pump, valves, or cylinders.
• Tighten bolts: If any parts are loose, tighten them properly.
• Lubricate moving parts: Ensure all moving parts are adequately lubricated.
