- ISO 9001 Quality Management System: Full production link quality control
- Custom enterprise enhanced standards formulated for heavy-duty commercial vehicles, focusing on frame load-bearing, powertrain durability and brake safety applicable to mining & long-distance transportation scenarios
Core definition under unified trucks remanufacturing standard:
Second hand trucks remanufacturing is an industrialized systematic production process, which restores used trucks to OEM new vehicle performance parameters, safety coefficient and service life, rather than temporary maintenance or appearance renovation.
Stage 1: Incoming Vehicle Access & Elimination Standards (Admission Threshold)
Before heavy duty trucks remanufacturing, all second-hand trucks undergo strict condition evaluation; unqualified vehicles are directly scrapped and rejected to avoid remanufacturing irreparable defective chassis:
Total working hours & vehicle age screening
Excessively aging trucks with severe metal fatigue are eliminated
Whole vehicle non-destructive detection
Magnetic particle & penetrant testing for frame longitudinal beams, cross beams, connection points; trucks with large-area cracks, permanent torsion deformation cannot enter remanufacturing procedures
Powertrain preliminary diagnosis
Engine cylinder wear, gearbox internal clearance, drive axle damage are detected via computer diagnosis and oil spectrum analysis
Record archiving
Original vehicle working history, fault records are sorted to formulate targeted personalized remanufacturing scheme
Stage 2: Full Disassembly & Classification Management Standards
Zero skipping of disassembly steps is mandatory, which is the biggest difference from simple refurbishment:
- Complete split down to single bolts, bearings, sealing rings; the whole vehicle is divided into 6 major modules: chassis frame, engine, transmission assembly, walking & suspension, hydraulic system, electrical & cabin parts
- Three-category classified management of all components: Repairable parts: Structural steel pieces, gear shells, valve bodies, repaired via welding, surfacing, precision machining; Mandatory replacement vulnerable parts: All oil seals, bearings, piston rings, hoses, brake pads, aging wiring harnesses (100% brand new replacement without reuse); Scrapped parts: Severely deformed, fatigued metal components directly discarded
- Unified serial number marking for each part, corresponding to vehicle VIN code for full traceability
Stage 3 Cleaning, Structural Repair & Chassis Reinforcement Standards
Deep Cleaning Standard
- Large structural frames: Sandblasting + high-pressure hot steam cleaning to remove rust, mud, cement attachments and old paint layers
- Precision hydraulic parts, engine internal components: Ultrasonic cleaning to clear oil sludge, metal abrasive dust inside oil passages
- Acceptance requirement: No residual dirt inside oil circuits, no rust spots on load-bearing surfaces
Frame Structural Repair Standard
- All hidden fatigue cracks are fully welded with low-temperature structural welding wire
- Deformed beams undergo hydraulic precision correction, frame alignment error controlled within 0.05°
- Stress concentration points are reinforced with wearing steel plates for heavy-load working conditions
- All welding seams pass ultrasonic nondestructive testing to ensure no internal welding defects
Stage 4 Core Assembly Overhaul Technical Standards
Engine Remanufacturing Standard
- Disassemble the whole engine, replace cylinder liner, piston ring, crankshaft bearing, valve group and all sealing accessories
- Calibrate fuel injection pump and injector parameters to restore rated power output and original fuel consumption level
- Bench dynamometer test: Power ≥95% of new engine rated power, crankcase pressure within qualified range, no blue smoke/black smoke during operation
Transmission & Drive Axle Standard
- Disassemble gearbox, replace worn gears, friction plates and synchronizers, adjust meshing clearance
- Four-wheel drive and rear axle differential are fully inspected and calibrated to eliminate power slipping and abnormal noise under full load
- No oil leakage at all joint surfaces after assembly
Brake & Suspension System Standard
- Air brake pipeline, brake chamber, brake shoe are all renewed; braking response is synchronized on left and right sides
- Leaf springs, shock absorbers, balance arms are replaced entirely to ensure stable vehicle running without deviation during braking
- Adapted to bumpy mine roads and long-distance highway transportation dual scenarios
Hydraulic Lifting System
All aging rubber seals, hydraulic pipelines are updated; system pressure is calibrated strictly according to OEM parameters to eradicate slow lifting, insufficient tipping force and oil leakage faults
Stage 5 Electrical System Renewal & Whole Vehicle Assembly Standards
- Aging whole remanufactured trucks wiring harness, sensors, instrument panels, control switches are fully replaced to avoid short-circuit failures
- Assembly is carried out strictly in accordance with OEM assembly sequence and torque standard; each bolt is tightened with torque wrench and recorded
- Cabin interior renovation: Damaged seats, door panels, rubber strips are replaced; interior is cleaned and refurbished completely
Stage 6 Anti-Corrosion Spraying & Whole Vehicle Traceability Marking Standards
- The whole REMAN ROAD remanufactured trucks undergoes standardized multi-layer anti-rust coating construction. Anti-rust epoxy primer is sprayed on chassis and all metal structural parts firstly, followed by wear-resistant topcoat paint for exterior body panels. The finished paint layer features strong salt spray resistance, anti-oxidation and scratch resistance, adapting to high-temperature, humid, saline-alkali and mining harsh environments worldwide.
- After painting is finished, exclusive permanent traceability serial numbers and vehicle identification codes are printed on the frame and body surface. A unified digital archive is created matching the VIN code, which records all disassembly data, flaw detection reports, parts replacement lists and assembly records throughout the remanufacturing process.
- Complete vehicle interior and exterior finishing inspection is conducted to check paint uniformity, assembly gaps and cabin finishing quality, ensuring consistent appearance quality of all finished remanufactured trucks in Botswana.
Stage 7 Pre-Delivery Archive Sorting & Warranty Configuration Standards
- All inspection documents, component overhaul records, test data and certification files are sorted, bound and archived electronically and in paper versions synchronously. Customers can acquire full remanufactured trucks lifecycle records anytime for customs clearance, registration and subsequent resale.
- Global unified warranty documents are configured for each truck. Core assemblies including engine, gearbox, drive axle and brake system are covered by official after-sales warranty. Detailed warranty clauses, maintenance scope and overseas service channels are clearly listed.
- Final cosmetic cleaning for the whole remanufactured trucks is completed before delivery; spare vulnerable parts and operation manuals are equipped as supporting accessories for end users.
Stage 8: 72-Hour Full-Load Durability Test Acceptance Standard
