Truck Crane Maintenance Instructions | XCMG Sany Zoomlion Truck Crane Parts Guide

Essential Daily & Periodic Maintenance Instructions for Truck Cranes

Regular scientific maintenance is critical to extend service life, reduce failure rate, and ensure safe operation of heavy-duty truck cranes. Whether you own XCMG, SANY or Zoomlion mobile cranes, standardized daily inspection and component replacement can effectively avoid sudden downtime and high repair costs. Below are practical maintenance guidelines for heavy truck crane operators and fleet managers.

1. Hydraulic System Maintenance

Check hydraulic oil level, oil cleanliness and pipeline leakage every week. Replace hydraulic filters and aging oil hoses regularly to prevent oil blockage and pressure instability. Damaged hydraulic seals and piston parts must be replaced with high-quality XCMG Sany Zoomlion truck crane parts to maintain stable lifting performance under heavy loads.

2. Wire Rope & Lifting Mechanism Inspection

Inspect wire rope wear, corrosion, broken wires and lubrication condition before each use. Clean and grease the ropes periodically. Check winch brakes, sheaves and torque components. Worn brake pads and rotating bearings should be replaced with genuine crane spare parts to eliminate lifting safety hazards.

3. Chassis & Travelling System Care

Regularly examine tire pressure, suspension components and steering system. Fasten chassis bolts and check axle lubrication conditions. For heavy working conditions, use durable chassis accessories to reduce vibration damage during crane travelling.

4. Electrical System & Safety Device Calibration

Clean electrical connectors, check wiring aging and battery status. Calibrate the load moment indicator, limit switches and alarm systems monthly. Unqualified electrical parts will cause system failure, so always choose matched original truck crane parts for replacement.

5. Engine & Cooling System Maintenance

Replace engine oil, fuel filters and air filters strictly following working hour cycles. Clean radiators and check cooling liquid concentration to prevent engine overheating in high-temperature construction environments.
