Structural Repair & Fabrication
Frame damage assessment, repair methods and fabrication.
Lessons
- 01Structural Load Paths, Materials, and Damage AssessmentIdentify trailer load paths and materials, inspect structural damage systematically, and determine when engineering review is required.
- 02Repair Engineering, Geometry Control, and Structural ReplacementDevelop an authorized repair plan that controls load paths, support conditions, alignment, straightening, and replacement sequence.
- 03Structural Fabrication, Welding, and Mechanical JoiningExecute controlled structural fabrication using verified materials, qualified joining procedures, appropriate fasteners, and corrosion protection.
- 04Repair Verification, Failure Analysis, and Release DocumentationValidate repaired structures, troubleshoot recurring defects, and create a traceable record supporting safe return to service.
- 05Structural Worksite Isolation and Hot-Work ControlPrepare a controlled structural-repair worksite by addressing cargo residues, concealed combustibles, hazardous coatings, energy sources, and post-work fire surveillance.
- 06Corrosion Protection, Sealing, and Drainage RestorationRestore environmental protection after structural work without creating moisture traps, incompatible material interfaces, or inaccessible corrosion sites.
- 07Deck, Floor, and Cargo-Restraint StructureService trailer decks, floors, and cargo-restraint attachments using their local loading, support, fastening, and access requirements.
- 08Coupling, Support, and Running-Gear Mounting InterfacesDiagnose and service structural interfaces for couplings, landing gear, suspension brackets, and sliding running gear without masking fit or load-transfer faults.
- 09Ramps, Gates, and Articulated Body StructuresService moving trailer structures by controlling stored energy, maintaining pivot geometry, and verifying supports, latches, stops, and operating clearances.
- 10Guards, Identification, and Modification ControlControl structural changes that affect protective guards, regulated equipment, vehicle identity, and the distinction between repair and redesign.
