Construction Truck Maintenance Guide

[MikePhua]

Introduction
Maintaining construction trucks is vital to ensure safety, reliability, and longevity of these heavy-duty vehicles essential for construction and industrial projects. Regular preventive maintenance minimizes downtime, reduces costly repairs, and enhances operator confidence.
Engine Maintenance

• Regularly check and change engine oil and filters to maintain lubrication and remove contaminants.
  
• Monitor coolant levels and replace coolant as needed to prevent overheating and corrosion.
  
• Inspect belts and hoses for cracks, wear, or leaks, replacing as necessary to prevent engine failure.
  

Fuel and Hydraulic Systems

• Keep fuel filters clean and replace regularly to avoid clogged injectors and poor engine performance.
  
• Inspect hydraulic fluid levels and quality, topping off or replacing to maintain smooth operation of lifts and other hydraulics.
  
• Check hydraulic hoses and fittings frequently for leaks or damage.
  

Brake System

• Regular inspections of brake pads, discs, and fluid levels ensure safe stopping power.
  
• Test air brake systems for leaks and proper pressure, correcting issues immediately.
  
• Replace worn brake components promptly to avoid accidents and legal liabilities.
  

Electrical System

• Keep battery terminals clean, cables tight, and check battery charge regularly.
  
• Inspect wiring harnesses and electrical connectors for damage or corrosion.
  
• Test all lighting systems, warning indicators, and horns to ensure proper function.
  

Tires and Wheel Alignment

• Regularly check tire pressure and look for abnormal wear patterns that indicate alignment or suspension issues.
  
• Rotate tires to promote even wear and extend tire life.
  
• Inspect wheels and rims for cracks or damage.
  

Body and Interior

• Inspect exterior body panels, glass, mirrors, and wipers for damage and proper operation.
  
• Ensure seat belts and seating elements are intact and functional.
  
• Keep the cab clean and well-maintained for operator comfort and safety.
  

Undercarriage and Suspension

• Regularly inspect suspension components, mounts, and the frame for cracks or looseness.
  
• Grease all pivot points, joints, and bearings according to manufacturer schedules.
  

Scheduled Maintenance

• Daily checks include fluid levels, lights, tire condition, warning signals, and control systems.
  
• Weekly inspections involve more in-depth checks like belts, hoses, and filter conditions.
  
• Monthly to quarterly maintenance may cover oil changes, transmission fluid checks, and brake system servicing.
  
• Annual maintenance focuses on extensive inspections, system flushes, and replacement of high-wear parts as recommended by OEM guidelines.
  

Glossary

• Preventive Maintenance: Routine service actions to prevent equipment failure before it occurs.
  
• Hydraulic Fluid: Liquid transferred through the hydraulic system to transmit power.
  
• Air Brake System: Brake mechanism using compressed air to apply pressure to brake pads.
  
• Torque Converter: A device that transmits and multiplies torque from the engine to the transmission.
  
• OEM: Original Equipment Manufacturer - company producing parts or equipment as designed.
  

Conclusion
A comprehensive maintenance program incorporating daily, weekly, monthly, and annual inspections keeps construction trucks in optimal condition and ensures safe, efficient operation. Understanding system interdependencies within engines, hydraulics, brakes, electricals, tires, and bodywork helps operators and maintenance teams anticipate issues and take preventive actions, saving time and costs while maximizing equipment lifespan.
