Off-Highway Trucks: Safety & Maintenance Inspection Checklist
Introduction
Off-highway trucks, including haul trucks, dump trucks, and other heavy-duty vehicles operating primarily in mining, construction, and other industrial environments, face extreme conditions that demand rigorous inspection and maintenance protocols. These specialized vehicles operate in challenging terrain, carry massive loads, and endure severe stresses that can accelerate component wear and increase safety risks if not properly monitored.
This comprehensive inspection checklist is designed to address the unique challenges of off-highway truck operation, helping operators and maintenance personnel identify potential issues before they result in costly downtime, safety incidents, or catastrophic failures. Regular inspections using this checklist help ensure operational readiness, maintain compliance with safety regulations, and maximize the service life and productivity of these valuable heavy equipment assets.
Off-Highway Truck Inspection Importance
- ⚠️ Extreme Operating Conditions: Off-highway trucks operate in harsh environments with excessive dust, vibration, and load stress that accelerate wear.
- 💰 High Downtime Costs: Unplanned downtime can cost thousands of dollars per hour in lost production and project delays.
- 🛑 Catastrophic Failure Risk: Component failures can lead to accidents affecting operator safety and causing extensive equipment damage.
- 📝 Regulatory Compliance: MSHA, OSHA, and other regulatory bodies require regular documented inspections of heavy equipment.
- ⏱️ Extended Service Life: Regular inspections and preventive maintenance can significantly extend equipment lifespan and ROI.
Inspection Requirements & Frequency
Pre-Shift Inspection: Required before each shift begins (daily or per operator change)
Weekly Inspection: More detailed inspection of key systems and components
Monthly Inspection: Comprehensive inspection of all major systems
Operating Hour Based: Certain components require inspection based on hours of operation (250hrs, 500hrs, 1000hrs)
Post-Incident Inspection: Required after any accident, near-miss, or unusual operating condition
Compliance Standards: MSHA (30 CFR 56/57), OSHA regulations, and manufacturer requirements
Equipment Information
Pro Tips for Off-Highway Truck Inspections
- Use the "Sense" Approach: Employ all senses during inspection - look for abnormalities, listen for unusual sounds, smell for burning odors, and feel for excessive heat or vibration in components.
- Document with Photos: Take photographs of any abnormal conditions or damage to provide clear documentation and track progressive issues over time.
- Check During Operation: Some issues only manifest during operation - have a qualified operator demonstrate functions while inspecting for leaks, noises, or abnormal behavior.
- Consider Environmental Factors: Account for site-specific factors like dust levels, rock fall risks, water exposure, or corrosive materials that may accelerate wear on specific components.
- Prioritize Safety-Critical Systems: Always give extra attention to braking systems, steering, tires, and operator safety features since failures in these areas can have the most serious consequences.

- Inspect for leaks with components under pressure
- Test lift cylinder function through full range
- Verify cylinder sync during operation
- Measure drift with body under load
- Check hydraulic pressures at test ports
- Inspect all high-pressure hoses and fittings
- Evaluate hydraulic performance under load
Structural Inspection Method
- Clean critical areas before inspection
- Use proper lighting to identify cracks
- Follow manufacturer's stress point guidance
- Inspect welds for cracking or separation
- Check articulation joints with steering cycled
- Verify alignment of major components
- Document findings with photos and measurements
- Inspect chassis under loaded conditions when possible
Tire & Wheel Assessment
- Measure tire pressure when cool
- Inspect tire sidewalls for cuts and damage
- Check tread for abnormal wear patterns
- Inspect rims for cracks or deformation
- Verify all lug nuts are tight to specification
- Check for bead damage or leakage
- Evaluate matching of dual tire assemblies
- Document tire condition with measurements
