Heavy Equipment Inspection

Articulated Dump Truck

Tires: Make sure all tires are the correct size. Measure and record tread depth for each one. Examine treads and sidewalls for tears and other damage. Remember to check the inner sidewalls as well. Also, look at the inside of all wheels for leaking axle seals.
Rear: With the bed raised and safety bar engaged, check the rear frame, bed hinge pins, wear pads, differential and driveshaft for any distorted areas, cracks or welds. Also examine the underside of the bed and the emergency and parking brake systems.
Dump Cylinders: The dump cylinders are exposed and can be damaged during loading operations. They should be closely checked for impact damage.
Articulation: The articulation joint and steering cylinders must be examined closely. Watch for excessive play in the components as they move through their normal range of motion.
Cab Rear: There are several important components mounted on the back of the cab, including hydraulic fluid sight glasses. The steering accumulator and transmission pump are also located here and should be checked for leaks.
Engine: Engine inspection should include a check of all fluid levels. Also note the condition of all belts and hoses as well as the radiator and exhaust system. Keep an eye out for excessive oil leaks.
Cab: Inspect the overall condition of the cab. Note any broken or cracked glass, dented sheet metal or structural rust.
