●Regular heavy equipment maintenance involves scheduling routine tasks to ensure machinery operates at peak performance. Preventive maintenance also involves visual inspections, technical monitoring and oil analysis to anticipate problems and fix them before they become serious.
●Heavy equipment maintenance checklist
This maintenance checklist has been broken down into checks that are required daily, versus checks that are required based on operating hours. Each piece of construction equipment will be used at different times and for different durations. That’s why it is best to schedule preventive maintenance based on hours in operation instead of by date.
●Daily pre-operation checks:
Before firing up the equipment, operators are required to perform a visual inspection and log it into a pre-operational log book before signing off and beginning their shift. This includes a variety of hands-on and visual inspections before, during, and after operating the heavy equipment. Operators should note any issues as soon as they are noticed so they can be addressed in a timely manner.
●Pre-start checks (walk around)
Before you start the heavy equipment, perform these checks:
Parking: Is the piece of equipment parked in a safe space?
Hazards: Are there any tripping hazards? Are there any overhead hazards?
Damaged/worn/loose parts: Inspect the overall condition.
Leaks: Look under the equipment for any wet spots.
Fluid analysis: Check engine oil fluid levels, power steering fluid levels, windshield washer fluid.
Undercarriage: Look for worn or missing bogies or rollers, track tension, and overall condition on excavators.
Check tires: Look for low or sagging tires, cuts to cord depth, damage, and general wear.
Valve stems: Are caps present and securely screwed?
Steering: Check for excessive play.
Belts: Check for cracks, fraying, or splits.
Hoses: Check for pinched, cracked, or loose hoses.
Suspension system: Does the equipment bounce or vibrate when it’s in motion? Listen for any irregular noises when going over bumps or turning the wheel.
Battery: If accessible, inspect cables, clamps, and connections. Are any loose? Is there any corrosion?
Cab condition: Check glass, mirrors, wiper blades, horn, and seat belts.
●Warm-up checks
Perform these checks after the equipment has been running for five to 10 minutes:
Air filter system: Check for warnings. Replace or clean the filter if necessary.
Listen for unusual noises
Dashboard gauges: Do they appear to be working and at safe, operating levels?
Lights: Test the lights. Headlights, high beams, signal lights, brake lights, and backup lights.
Hydraulic system: Test all hydraulic lines and systems. For example, with a dump truck, raise the dump body, or with an excavator, move the bucket, stick, and boom. Listen and watch for issues. Are there any leaks? Is everything functioning properly? Are there any irregular noises?
Check fluid levels: Engine, steering tank, hydraulic oil, power terrain, engine coolant, and swing drives.
Brakes: Test that the brakes work properly.
●Daily operating checks
During operation, watch and listen for irregularities:
Listen for unusual noises
Monitor gauges
Feel for excessive vibrations
Watch for any equipment performance changes
●Every 250 to 500 hours:
Around 250 to 500 hours, it is best practice to schedule a basic engine service. This involves a number of checks and actions:
Perform oil changes
Change oil filters
Change engine air filters
Change fuel filters
Oil change intervals will rely on the quality of oil and filter being used in each piece of equipment.
●Every 1,000 to 1,200 hours
Replace cabin air filters
Replace coolant filter (if applicable)
Inspect air dryer (if applicable)
