Belly dump trailers are built for tough work — hauling heavy loads, constant dumping cycles, and rough jobsite conditions. That same hard use means they experience unique wear and tear. At Lone Star Trailer Services, we know the special components that make belly dumps unique — and we know how to repair them right.

What Makes a Belly Dump Trailer Unique — and How We Repair It:

• Hopper Body & Walls – Continuous impact from rock, sand, or gravel can cause dents, cracks, and metal fatigue. We repair, reinforce, and weld hopper bodies to restore strength.

• Dump Gates & Hinges – Heavy use wears out hinges, latches, and gate edges. We replace or rebuild gates for smooth, even dumps every time.

• Hydraulic Cylinders & Lines – Leaking hoses, damaged cylinders, or bad seals can shut you down. We service and replace hydraulics to keep gates operating with power and precision.

• Air Systems & Valves – Pneumatic controls are essential for gate operation. We repair air lines, valves, and tanks to eliminate leaks and restore reliable function.

• Frame & Crossmembers – The stress of constant loading and dumping often leads to cracks and bent supports. We provide welding, reinforcement, and straightening for long-term durability.

• Suspension & Axles – Heavy-duty hauling puts strain on springs, airbags, axles, hubs, and bearings. We inspect and service all suspension components to prevent breakdowns.

• Brakes & Drums – With constant stop-and-go hauling, brake systems wear quickly. We replace brake shoes, drums, slack adjusters, and air chambers to keep you safe.

• Tires & Wheels – Uneven loads can cause irregular wear or blowouts. We mount and balance new tires and repair wheels to keep your rig rolling.

• Lighting & Wiring – Dust, rocks, and debris damage electrical systems. We repair or replace harnesses, connectors, and lights to maintain compliance and safety.
