Preventive Maintenance Vehicle Inspection Checklist

Heavy vehicles and construction utility equipment carry out demanding work. A preventive maintenance inspection is a planned check of the machine and its systems so that faults are found and fixed before they stop the machine or cause an incident. This checklist covers 65 items across the machine from the ground up, machine-specific checks, the engine compartment, the cab, and the exterior and interior. It is written for practitioners who need a ready-to-use template for a walkaround inspection of heavy vehicles and other construction utility equipment.

What a Preventive Maintenance Vehicle Inspection Covers

The inspection begins with the machine from the ground. You check the headlights, then the steps, handrails and grab bars, and the undercarriage. You inspect the brakes through their filters, cables, parking brake, brake fluid levels, and fasteners. You check the electrical and hydraulic circuits, and the hydraulic oil levels, cylinders, hoses, and fittings. You examine the fuel tank for a cap in place and no deformation. You look at the lift arms and body, the grease lines, and check for leaks. You inspect the work tools, including cutting edges, G.E.T. components, and teeth. You check the tyres for tread, valve connections, and inflation level, the rims for wheel nuts and damage, and the axles or drive shafts.

Machine-Specific Inspections

The checklist then moves to checks that depend on the machine in front of you. - **Wheeled machine:** tyres, rims, and axles or drive shafts. - **Tracked machine:** undercarriage bearings, tensioner, and sprockets. For metal tracks, you inspect pads and links. For rubber tracks, you inspect the rubber attachment, torsion axles, and tension. Carrying out the section that matches the machine keeps the inspection relevant and avoids checking components that are not fitted.

Engine Compartment Inspection

In the engine compartment, you check fluid levels: engine oil, radiator, engine coolant, and transmission oil. You inspect the air filter, belts and hoses, and battery connections. You also check covers and guards are in place. Low or contaminated fluids, a clogged air filter, a worn belt or hose, or a loose battery connection can each lead to a breakdown or further damage. Checking them as part of a planned inspection lets you deal with them before they become unplanned repairs.

Cab and Exterior and Interior Checks

On the exterior, you check the headlights, wipers and washer fluid level, and windows and mirrors. You check the anti-tip system. In the interior, you inspect the seat, fire extinguisher, horn, lighting, and the gauges, switches, and controls. You check the anti-tip system again, the seat belt installation date, the windows and mirrors, and the alarms. The anti-tip system and the seat belt are safety-critical items. Recording the seat belt installation date supports the replacement schedule. The fire extinguisher and the alarms need to be present and in working order before the machine is used.

How to Carry Out the Inspection

1. Record the date, who prepared the inspection, and the location. 2. Work from the ground up and follow the checklist in order so the sequence stays consistent from one inspection to the next. 3. Complete the ground-level check first, then move to the machine-specific section for a wheeled or tracked machine. 4. Inspect the engine compartment and the fluid levels and components. 5. Inspect the cab, then the exterior and interior checks. 6. For every item, record whether it is completed with no issues found or not yet done. Use the checklist as the tool that supports the walkaround. It holds the items and the order so you can carry out the inspection the same way each time and keep a record of what you found.

Frequently Asked Questions

A preventive maintenance inspection is a planned walkaround and systems check of heavy vehicles and construction utility equipment. It covers the machine from the ground, the undercarriage, the engine compartment, the cab, and the exterior and interior. It does not wait for a breakdown. It is carried out before the machine goes to work, not after it fails.

Heavy vehicles and construction utility equipment work hard in conditions that accelerate wear. Loose wheel nuts, low hydraulic oil, a damaged brake cable, or a worn tyre tread can stop a machine or cause an incident. A preventive check catches these conditions early, while they can still be fixed on a planned basis rather than as an emergency. It also helps you get full service life from tracks, tyres, tools, and fluids.

You begin with a ground-level check of the whole machine: headlights, steps, handrails and grab bars, undercarriage, brakes, electrical and hydraulic circuits, hydraulic oil, fuel tank, lift arms, body, grease lines, leaks, tools, tyres, rims, and axles or drive shafts. You then move to machine-specific checks for wheeled or tracked machines. For wheeled machines you look at tyres, rims, and axles. For tracked machines you check undercarriage bearings, tensioners, sprockets, metal track pads and links, and rubber track attachments, torsion axles and tension. After that you inspect the engine compartment, including fluid levels, the air filter, belts and hoses, battery connections, and covers and guards. Finally you inspect the cab and the exterior and interior, covering headlights, wipers and washer fluid, windows and mirrors, the anti-tip system, the seat, fire extinguisher, horn, lighting, gauges, switches and controls, seat belt installation date, and alarms.

Record the date, who prepared the inspection, and the location. Work from the ground up so you do not miss anything, and follow the order of the checklist. For each item, record whether it is completed with no issues found or not yet done. For tracked machines, check undercarriage bearings, tensioners, sprockets, metal track pads and links, and rubber track attachment, torsion axles and tension. For wheeled machines, check tyre tread, valve connections and inflation level, and rim wheel nuts and damage. Use the checklist as the tool that supports the walkaround. It holds the sequence and the items so you can carry out the inspection consistently each time.
