Quality Control

Quality Control

Qingdao Alston Motors Co., Ltd follows a practical quality control process for refurbished HOWO trucks and commercial transport vehicles intended for export markets across Africa, the Middle East, Central Asia, and other developing regions.

The company’s quality control work focuses on mechanical condition, operational reliability, component durability, and long-term serviceability under real transport and working conditions. Instead of concentrating only on exterior appearance, the inspection process places greater attention on critical systems that directly affect vehicle stability, maintenance cost, and long-distance operating performance.

Every refurbished truck undergoes multiple inspection, maintenance, testing, and verification procedures before export delivery.

1. Vehicle Selection & Initial Inspection

Before refurbishment begins, each used HOWO truck undergoes an initial inspection to evaluate structural condition, mechanical status, and refurbishment suitability.

Inspection areas include:

• Chassis structural condition
• Cabin condition
• Tire wear and wheel condition
• Suspension systems
• Oil leakage inspection
• Rust and corrosion condition
• Frame and body structure inspection

Particular attention is given to major components such as the engine, gearbox, and axle systems, since these directly affect long-term operating reliability and maintenance cost.

Vehicles with serious structural damage or unsuitable mechanical condition are excluded from refurbishment processing.

2. Documentation & Vehicle Verification

Vehicle records and related documentation are checked before refurbishment procedures begin.

Verification may include:

• Vehicle registration records
• Service and maintenance history
• Mileage information
• Ownership records
• Export documentation
• Vehicle identification information

This process helps improve export compliance, vehicle traceability, and quality management consistency.

3. Mechanical Inspection Procedures

After initial evaluation, experienced technicians and engineers perform detailed inspections of major mechanical systems.

Inspection procedures include:

• Engine inspection
• Transmission inspection
• Brake system inspection
• Steering system inspection
• Suspension inspection
• Cooling system inspection
• Hydraulic system inspection

Components showing excessive wear, leakage, instability, or operational issues are repaired, refurbished, or replaced according to workshop standards and export requirements.

4. Diagnostic Testing & System Evaluation

Professional diagnostic equipment is used to evaluate electrical systems, engine operating condition, and overall vehicle performance.

Diagnostic testing helps identify hidden faults or system abnormalities that may not be visible during standard visual inspection procedures.

Testing may include:

• Electrical system diagnostics
• Engine operating data inspection
• Battery and charging system testing
• Sensor and circuit inspection
• Operational system evaluation

For some export markets, selected vehicles may also be converted to simplified mechanical configurations to improve long-term maintenance accessibility under local operating conditions.

5. Refurbishment & Component Replacement

Based on inspection results, vehicles undergo refurbishment, maintenance, and replacement of necessary components.

Refurbishment work may include:

• Cabin refurbishment or replacement
• Chassis maintenance and repainting
• Interior refurbishment
• Tire replacement
• Electrical system repair
• Pipeline and accessory replacement
• Upper body replacement or installation

Depending on customer requirements and application scenarios, trucks can also be configured with dump bodies, tanker systems, mixer drums, cargo bodies, or other specialized transport structures.

6. Road Testing & Operational Verification

Each refurbished vehicle undergoes road testing before shipment to verify actual operating performance under driving conditions.

Testing focuses on:

• Brake response
• Steering stability
• Gear shifting performance
• Acceleration performance
• Noise and vibration condition
• Driving stability and operating comfort

Road testing helps verify vehicle operating condition before export delivery and reduces potential operational risks during long-distance transport work.

7. Final Inspection & Export Preparation

Before shipment, every vehicle undergoes a final inspection and export preparation process.

Final verification procedures include:

• Key component inspection
• Brake system testing
• Engine performance verification
• Electrical system inspection
• Exterior finishing inspection
• Operational system verification
• Export preparation inspection

The company focuses on maintaining both operational reliability and practical long-term usability throughout the refurbishment and export process.

Quality Documentation & Traceability

Inspection records and refurbishment documentation are maintained for each vehicle throughout the refurbishment process.

Documentation may include:

• Inspection reports
• Maintenance procedures
• Parts replacement records
• Operational testing records
• Quality verification documents

These records support vehicle traceability, export quality management, and long-term after-sales service coordination.

After-Sales Support

Alston Motors also provides after-sales support services for overseas customers and fleet operators.

Support services include:

• Spare parts assistance
• Technical consultation
• Maintenance guidance
• Remote troubleshooting support
• Overseas service coordination

For selected maintenance components and service items, replacement support may also be provided according to project requirements and operating conditions.
