The XCMG QUY55 crane is a powerhouse in construction and heavy machinery, but even the most reliable equipment can encounter minor issues. Whether it’s an engine that won’t start, a hydraulic system failure, or a crane arm that refuses to move, these problems can lead to costly downtime. Fortunately, with the right knowledge and XCMG QUY55 crane troubleshooting techniques, you can resolve these issues quickly and get back to work.

This guide will walk you through step-by-step solutions to the most common XCMG QUY55 crane faults. Plus, we’ll show you how our professional technical team and high-quality crawler crane undercarriage parts can keep your crane in peak condition.

 Engine Won’t Start? Here’s What to Do!

A non-starting engine is one of the most common issues crane operators face. Here’s how to troubleshoot:

Check the Fuel Level:

Ensure there’s enough fuel in the tank. Running out of fuel is a simple but often overlooked problem.

Inspect the Battery: 

A dead or weak battery is a frequent culprit. Confirm that the battery is fully charged and the terminals are clean and secure.

Examine the Starting Circuit: 

Check for loose connections, damaged wires, or faulty switches in the starting circuit.

Hydraulic System Failure? Follow These Steps!

The hydraulic system is the lifeblood of your crane’s operation. If it fails, here’s how to diagnose and fix the problem:

 Check the Hydraulic Oil: 

Ensure there’s enough hydraulic oil and that it’s clean. Contaminated or low oil levels can cause system malfunctions.

 Inspect the Hydraulic Pipeline: 

Look for leaks, cracks, or loose fittings in the hydraulic lines. Even a small leak can disrupt performance.

 Test the Hydraulic Pump: 

Confirm that the hydraulic pump is functioning correctly. A faulty pump can lead to a complete system breakdown.

Crane Arm Won’t Move? Try These Fixes!

If your crane arm refuses to lift or lower, follow these steps to identify and resolve the issue:

 Check Hydraulic Pressure: 

Ensure the hydraulic system pressure is within the normal operating range. Low pressure can restrict arm movement.

 Inspect the Joystick: 

Confirm that the joystick is functioning properly. A malfunctioning joystick can prevent signal transmission to the crane arm.

 Examine the Limit Switch: 

Check if the limit switch has been triggered. This safety feature can sometimes stop arm movement if activated accidentally.
