Expert structural repairs and custom welding for all trailer types.
Trailer Repair Near Me — Mobile Welding & Structural Repairs
Trailers take a beating on every highway mile — road vibration, shifting loads, corrosion, and dock impacts all compromise structural integrity. A cracked crossmember or damaged landing gear puts your equipment out of service and your DOT compliance score at risk. Weldon's Truck & Trailer provides expert mobile structural service and field fabrication in Kingman, Arizona and throughout a 200-mile service area.
Mobile Structural Work and Field Fabrication for Commercial Trailers
Our certified technicians perform MIG, stick, and aluminum welding on every commercial trailer type — flatbeds, dry vans, reefer units, step deck trailers, lowboy trailers, tanker trailers, and specialty equipment. We bring professional mobile rigs to your location whether your equipment is at a shipper's dock, a truck stop, or on the roadside. When you need to restore trailer damage quickly to keep your load moving, our crew dispatches immediately. Every structural repair meets DOT and FMCSA roadworthiness standards and is documented for your fleet and annual inspection records.
Trailer Types We Service
Commercial trailer service requirements vary by equipment type. Our technicians are experienced across all major configurations and carry materials on every visit to address the most common structural failures on each type.
Dry Van Service and Panel Repair
Dry vans accumulate damage from dock impacts, moisture intrusion, and load cycles. We repair cracked or broken crossmembers, patch and replace damaged wall panels, fix leaking roof sections, and address floor deterioration. Door systems are a frequent failure point — we rebuild roll-up door mechanisms, replace swing door hinges and latches, adjust door seals, and restore rear frame damage that prevents doors from closing squarely.
Flatbed and Step Deck Restoration
Flatbed trailers carry heavy, abrasive cargo that wears decks and damages structural components. We restore cracked stake pockets, bent or broken side rails, rusted-out support channels, and worn deck boards — both hardwood and apitong decking. Tie-down anchor and D-ring replacements keep cargo securement compliant with FMCSA regulations. We also address frame twist and crossmember damage from overloading or impact, restoring structural straightness for DOT annual inspections.
Reefer Trailer Structural Service
Reefer trailers demand tight structural integrity to maintain temperature control. We address the aluminum frame, door system, and undercarriage — repairing impact damage, cracked floor sections, and failed door gasket supports. Units requiring diesel APU work alongside structural service can be handled in the same visit, minimizing downtime.
Structural and Mechanical Repairs
The frame, floor, and landing gear are the foundation of any commercial trailer. Failures in these components ground equipment immediately and create compliance hazards that must be resolved before the unit re-enters service.
Frame and Crossmember Repair
The frame and crossmember structure carries the full weight of cargo and the dynamic loads of highway travel. We perform structural metalwork on steel and aluminum frames — addressing cracked or broken crossmembers, bent main rails, and damaged floor support channels. Our technicians follow AWS structural standards and inspect every repair for full penetration and proper bead quality. High-impact areas — rear frames, ICC bumper mounting points, and tandem slider tracks — receive additional reinforcement when appropriate.
Trailer Floor and Decking Replacement
Deteriorated floors are a cargo safety risk and a DOT violation. We replace hardwood, apitong, and composite decking on dry vans and flatbeds — sistering damaged joists, reinforcing perimeter rails, and installing new floor boards to full OEM specification. For spot work, we remove damaged sections and splice in new material meeting load-bearing requirements — all completed on-site, no tow required.
Landing Gear Service and Replacement
Landing gear failures leave trailers stranded at docks and prevent safe bobtail operations. We service and replace single-speed and two-speed manual assemblies, address bent or cracked gear legs, worn gear pads, and damaged cross-shaft tubes. Corrosion is the most common failure — we clean, restore, and protect assemblies to extend service life. Emergency service is available 24/7.
Coupling and Running Gear
Kingpin Replacement and Fifth Wheel Service
A worn or loose kingpin is a serious safety defect that will immediately fail a DOT inspection. We measure kingpin wear with calibrated gauges and replace worn pins when they exceed service limits. We also inspect fifth wheel coupling components on the tractor side, lubricate slider mechanisms, and examine the entire coupling system for cracks or deformation. Proper kingpin condition is essential for safe operation on Arizona's mountain routes.
Suspension Hangers and Axle Hardware
Trailer suspension hangers, spring seats, and U-bolts endure constant stress from load cycles and road shock. Cracked hangers and broken U-bolts allow axle shift, causing tire wear and eventually an out-of-service condition. We inspect and replace hanger brackets, equalizer beams, torque rods, and associated hardware. Walking beam suspension service on tandem axle trailers is a common job for aging equipment in harsh Arizona road conditions.
DOT Annual Inspection and Compliance Work
We help fleet operators prepare trailers for DOT annual inspection by identifying and addressing deficiencies before the inspector arrives. A pre-inspection visit covers ICC bumpers, reflective tape, mud flaps, lighting, and structural components. Getting a trailer through its annual inspection clean keeps equipment in service and your compliance score strong. All work is documented for your maintenance records.
Why Choose Weldon's for Trailer Service in the Kingman Area
Our technicians have years of experience on commercial trailers of every type. We follow AWS structural standards and perform every job to DOT specifications. Based in Kingman, Arizona, we dispatch across a 200-mile radius — mobile service eliminates the cost and downtime of towing to a fixed shop. Transparent estimates, fast dispatch, and thorough documentation have earned the trust of fleet operators and owner-operators across the Southwest.
Trailer Maintenance & Preventive Inspections
Preventive trailer maintenance reduces roadside failures and keeps your equipment out of the shop. Our technicians perform comprehensive trailer inspections covering the frame, floor, doors, lighting, brakes, and running gear. Routine service includes greasing fifth wheel plates and kingpins, adjusting slack adjusters, checking brake stroke measurements, lubricating landing gear assemblies, and inspecting tire condition on all trailer axles. Catching a cracked crossmember or a leaking brake chamber during a maintenance visit costs far less than an out-of-service roadside breakdown or a failed DOT annual inspection.
Trailer Hitches, Kingpins & Fifth Wheel Connections
The coupling system between tractor and trailer is a critical safety component. A worn kingpin that exceeds FMCSA measurement limits will immediately fail a DOT roadside inspection and is a serious accident risk. We measure kingpin wear using calibrated gauges and replace pins when they exceed service tolerances. Our technicians also inspect trailer hitches, fifth wheel jaw engagement, and coupling locks on specialty trailers — covering drop-deck, lowboy, and heavy-haul pintle hitch configurations in addition to standard fifth wheel couplings.
Major Trailer Repairs vs Minor Repairs — Field Triage
Not every trailer problem requires a full shop visit. Our technicians assess damage on-site and determine whether the repair can be completed in the field or requires a facility. Minor repairs — broken door latches, loose marker lights, glad hand replacements, brake chamber swaps, and small floor patches — are almost always completed in one visit. Major structural repairs like full crossmember replacement, bent main rail straightening, and tandem slider track rebuilds may require a shop setting, but we always maximize what can be done in the field to minimize your downtime and towing expense.
Trailer Brake Service — Chambers, Slack Adjusters & Air Lines
Trailer brakes are a primary DOT inspection point and a direct contributor to stopping safety on Arizona's mountain grades. We replace brake chambers, spring brake actuators, slack adjusters, S-cam assemblies, brake drums, and brake shoes on trailer axles. Air line replacements — glad hands, hose assemblies, and glad hand seals — restore proper air delivery to the trailer brake system. After every trailer brake service we perform a brake stroke measurement and apply-release test to verify the system functions within DOT specifications before the trailer returns to service.
Trailer Body Repair & Panel Restoration
Dry van wall panels, reefer compartment liners, and flatbed side rails take constant abuse from loading equipment, shifting cargo, and road debris. We repair cracked or delaminated wall panels, patch damaged side boards, restore bent stake pockets, and fix door frame damage that prevents a square close. Body repairs are performed on-site using appropriate adhesives, fasteners, and structural reinforcement materials for the trailer type. Fleet operators can schedule panel restoration visits at their terminal or yard to keep trailers cargo-secure and professionally maintained.
Trailer Roof Repair — Low-Clearance Impact & Structural Damage
Low-clearance collisions are one of the most common sources of serious trailer damage. A roof impact from a bridge or overhead obstruction can damage roof bows, roof sheets, and door header framing — creating structural weakness and weather intrusion that damages cargo on subsequent loads. We repair aluminum and steel roof bow assemblies, patch and seal damaged roof sheets, restore door header framing, and address structural damage to side posts and rear frame corners. Every roof repair is sealed for weather-tightness before the trailer is returned to service.
