Dump Trucks Buyer Guide

• Used market prices typically range from $45,000 for older working units to $195,000+ for late-model, low-hour tri-axle and quint-axle configurations.
• Gross Vehicle Weight Ratings (GVWR) span from 33,000 lbs for single-axles up to 80,000+ lbs for multi-axle super dumps.
• Commercial vocational diesel engines typically achieve 500,000 to 800,000 road miles or 15,000 to 20,000 engine hours prior to major in-frame overhauls.
• Fuel burn averages 4.5 to 6.5 MPG in mixed road cycles or 4 to 8 gallons per hour in heavy stop-and-go jobsite conditions.
• Dump bodies generally range from 10 to 22 cubic yards, built from abrasion-resistant Hardox steel for rock or lightweight aluminum for sand and asphalt.
• Core applications include site grading, highway paving, quarry-to-job transport, land clearing, and municipal snow removal with plow attachments.

• 1Inspect double-channel frame rails for rust jacking, flaking between the liners, and stress fractures around crossmembers and suspension hangers.
• 2Check the telescopic hoist cylinder for chrome scoring, leaking wiper seals, and lateral wobble or slop when raised to full dump angle.
• 3Examine the dump box floor and side walls for washboard warping, patch welds, and critical thinning from abrasive aggregate impact.
• 4Check walking beam bushings, trunnion stands, and rubber suspension blocks (such as Hendrickson Haulmaax) for dry rot, play, and axle tracking issues.
• 5Engage the Power Take-Off (PTO) and hydraulic pump to test for smooth lift, positive hold, and feather-down function without shudder or chatter.
• 6Inspect auxiliary lift/drop pusher and tag axles for air bag leaks, pivot bushing play, and uneven tire wear patterns.
• 7Pull ECM data to cross-reference engine operating hours against the odometer, as high PTO idle hours cause premature engine wear not reflected in road mileage.
• 8Check tailgate air cylinders, hinge pins, and locking claws for deformation that could cause material spilling in transit.
• 9Scan the aftertreatment system (DPF/DEF/SCR) for frequent regeneration histories, face-plugging alerts, and exhaust manifold soot leaks.
• 10Inspect steer axle kingpins, tie-rod ends, and vocational tires for rock drill damage, sidewall gouges, and uneven shoulder wear.
