The SANY crane malfunction light is an important warning signal that helps operators detect potential issues before they lead to serious failures. When the fault light appears, it’s crucial to understand the possible causes and take the right steps to resolve them. This article will explain the main reasons and effective solutions for malfunction light display on SANY cranes, helping you maintain safe and efficient crane operations.
One of the most common reasons for the malfunction light display on a SANY crane is low battery voltage. If the crane has been idle for a long period, the battery gradually discharges. When voltage drops below the required level, the fault indicator light activates automatically.
✅ Solution: Check the battery voltage with a multimeter. Recharge the battery if it’s below the standard level, or replace it if it can no longer hold charge. Maintaining proper battery health ensures reliable startup and prevents false fault alarms.
The sensors on a SANY crane are critical for monitoring parameters such as oil pressure, hydraulic temperature, and liquid level. A malfunctioning sensor can send incorrect signals to the control system, causing the warning light to appear.
✅ Solution: Inspect the relevant sensors for damage or contamination. Clean the connectors, and if necessary, replace the defective sensor. Always use genuine SANY or OEM crane parts to ensure long-term reliability.
Electrical or wiring problems can also lead to malfunction light display on a SANY crane. Common issues include blown fuses, loose connections, or damaged wiring. Even a small disruption in the control circuit can trigger the warning light.
✅ Solution: Conduct a full inspection of the crane’s electrical circuits. Repair or replace faulty wiring and ensure all connectors are secure. Keeping the circuit system in good condition reduces downtime and prevents potential hazards.
The hydraulic system is the heart of any SANY crane. If hydraulic components fail or oil levels drop, the system pressure becomes unstable, triggering the fault indicator light.
✅ Solution: Regularly inspect the hydraulic system for leaks, abnormal sounds, and oil contamination. Replace hydraulic filters and oil at recommended intervals to keep the system running smoothly.
Start and operate the crane regularly to maintain battery charge.
Perform periodic sensor calibration and cleaning.
Check circuit continuity after long-term storage or repairs.
Use high-quality hydraulic oil suitable for your working environment.
