Quality Control for Refurbished Used HOWO Trucks

Qingdao Alston Motors Co., Ltd follows a structured quality control process for refurbished used HOWO trucks and commercial vehicles prepared for overseas markets.

The quality control process focuses on vehicle condition, mechanical function, operational stability, refurbishment verification and pre-shipment readiness. Exterior appearance is checked, but greater attention is placed on the systems that directly affect safety, reliability, maintenance and day-to-day commercial operation.

Quality control is carried out at different stages of the preparation process, from initial vehicle screening to final operational verification before shipment.

The objective is not to treat every used truck as identical, but to identify its actual condition, verify completed refurbishment work and confirm that the vehicle corresponds with the agreed configuration before export.

1. Vehicle Selection and Initial Condition Assessment

Quality control begins before refurbishment work starts.

Each candidate vehicle is reviewed to determine whether its structural and mechanical condition is suitable for further preparation.

Initial assessment may cover:

• Chassis and frame condition

• Cabin structure

• Engine operating condition

• Gearbox and driveline condition

• Axle and suspension condition

• Steering system

• Brake system

• Tire and wheel condition

• Oil, coolant and air leakage

• Rust and corrosion

• Electrical condition

• Hydraulic systems

• Existing upper-body condition

Particular attention is given to major structural and mechanical systems because serious damage in these areas can affect long-term reliability and refurbishment value.

Vehicles with unsuitable structural condition or major mechanical problems that do not meet the intended refurbishment scope can be excluded before further processing.

2. Vehicle Identity and Order Specification Verification

The physical vehicle must correspond with the truck being prepared for the customer.

Before shipment, key vehicle information is checked against the confirmed order and available records.

Verification may include:

• Chassis or vehicle identification number

• Vehicle model

• Engine information where applicable

• Drive configuration

• Left-hand-drive or right-hand-drive configuration

• Axle arrangement

• Upper-body type

• Agreed truck specification

• Available registration or vehicle records

• Order-related export information

For used vehicles, historical records may not always be complete. For this reason, the quality control process places greater emphasis on verifying the physical vehicle, confirmed specifications and available documentation rather than relying only on historical records.

This helps reduce mismatches between the vehicle, customer order and export-related information.

3. Mechanical System Inspection

Major mechanical systems are inspected to identify wear, leakage, instability and abnormal operation.

Key inspection areas include:

Engine

Technicians check engine starting, idle stability, exhaust condition, visible leakage, abnormal noise, vibration and general operating response.

Transmission and Driveline

Gear selection, shifting response and driveline operation are reviewed to identify abnormal noise, vibration or unstable power transmission.

Axles and Suspension

Axle assemblies, suspension components and related mounting points are inspected for visible wear, damage and structural condition.

Brake System

Brake operation, air-system condition and visible components are checked before road testing.

Steering System

Steering response, visible linkage condition and abnormal free play are reviewed as part of operational inspection.

Cooling System

Radiator condition, coolant circulation, hoses, leakage and related components are checked because cooling performance is particularly important for trucks operating under high ambient temperatures and heavy loads.

The purpose of this stage is to identify issues that require repair or further verification before the truck progresses to final testing.

4. Electrical and Diagnostic Checks

Electrical and electronic systems are checked according to vehicle configuration.

Testing may include:

• Starting system

• Battery condition

• Charging system

• Dashboard functions

• Exterior lighting

• Warning indicators

• Wiring and connectors

• Selected sensors and circuits

• Electrical accessories

• Engine operating data where diagnostic access is available

Diagnostic equipment may be used on suitable vehicle configurations to identify faults that are not immediately visible during a basic inspection.

For mechanically configured vehicles, testing focuses more heavily on direct mechanical operation and conventional electrical systems.

The inspection method is therefore adapted to the actual vehicle rather than applying the same diagnostic procedure to every truck.

5. Refurbishment Quality Verification

Quality Control verifies refurbishment work after it has been completed.

The detailed repair and refurbishment process is handled by the workshop Production Line, while the Quality Control function checks whether the completed work corresponds with the agreed refurbishment scope.

Verification may cover:

• Mechanical repair completion

• Cabin repair or replacement

• Chassis repair

• Tire replacement

• Electrical repair

• Hydraulic repair

• Pipeline replacement

• Upper-body repair or installation

• Surface preparation

• Repainting

• Customer-requested configuration changes

Where components have been repaired or replaced, inspectors check installation condition and basic operational function before final vehicle approval.

This separation helps maintain a clear distinction:

Production Line repairs and prepares the truck.
Quality Control verifies the completed condition.

6. Truck-Type Functional Testing

Different truck types require different working-system tests.

Quality Control therefore includes application-specific verification rather than relying only on general chassis inspection.

Used HOWO Dump Trucks

Functional checks may include:

• Hydraulic lifting operation

• Dump-body raising and lowering

• Hydraulic leakage

• Cylinder and mounting condition

• Tailgate operation where applicable

HOWO Tractor Trucks

Inspection may include:

• Fifth-wheel condition

• Driveline operation

• Air and brake connections

• Chassis mounting areas

• Trailer-related interfaces

Concrete Mixer Trucks

Functional verification may include:

• Mixer drum rotation

• Forward and reverse drum operation

• Hydraulic system

• Supporting structures

• Control operation

Fuel and Water Tank Trucks

Checks may include:

• Tank mounting condition

• Pump operation

• Valves

• Pipelines

• Visible leakage

• Related working equipment

Cargo Trucks

Inspection may include:

• Cargo-body structure

• Side panels or fence structure

• Mounting points

• Chassis-body connection

These tests help verify whether specialized working systems operate as intended before shipment.

7. Road Testing and Operational Verification

A static inspection cannot fully confirm how a truck behaves while driving.

Refurbished vehicles therefore undergo operational testing before shipment where road-testing conditions allow.

Road testing focuses on:

• Engine response

• Gear shifting

• Steering stability

• Brake response

• Driveline behavior

• Acceleration

• Abnormal noise

• Vibration

• Dashboard operation

• General driving stability

Technicians observe whether the truck shows abnormal behavior that may not be apparent during workshop inspection.

If problems are identified, the vehicle can be returned for corrective work before another verification check.

Road testing is therefore treated as part of the quality-control loop rather than simply as a final demonstration.

8. Tire, Wheel and Visible Wear Inspection

Tires and wheels are important for both safety and operating readiness.

Inspection may cover:

• Tire tread condition

• Visible cracking or damage

• Uneven wear

• Wheel condition

• Wheel mounting

• Matching of tire specifications

• Spare tire arrangement where included

Other visible wear items may also be reviewed according to the agreed refurbishment scope.

Replacement decisions depend on vehicle condition, customer requirements and the refurbishment standard confirmed for the order.

9. Chassis and Structural Verification

Heavy-duty trucks used in mining, construction and infrastructure projects can experience repeated loading and rough-road stress.

For this reason, structural inspection remains an important part of the quality-control process.

Inspectors pay attention to:

• Main chassis rails

• Cross members

• Mounting points

• Suspension mounting areas

• Upper-body mounting

• Visible deformation

• Previous repair areas

• Corrosion

• Weld condition where applicable

For specialized vehicles, the relationship between the chassis and upper body is also reviewed.

The objective is to identify visible structural concerns that could affect the intended application of the truck.

10. Final Pre-Shipment Verification

After refurbishment, functional testing and road testing are completed, the truck undergoes a final pre-shipment review.

Final verification may include:

• Engine operating check

• Transmission operation

• Brake and steering confirmation

• Electrical system check

• Tire and wheel review

• Hydraulic or specialized system function

• Chassis and body condition

• Cabin condition

• Exterior finishing

• Vehicle identification

• Confirmed configuration

• Order specification

• Basic export preparation

The purpose of the final check is to confirm that the truck is consistent with the agreed order and ready to move from technical preparation to shipment coordination.

Final inspection does not replace destination-country customs, registration or statutory inspection requirements. Buyers should confirm applicable import and regulatory requirements for their own market.

Quality Documentation and Traceability

Quality-control records can help buyers understand what was checked and what work was completed before shipment.

Depending on the vehicle and order, records may include:

• Inspection records

• Refurbishment work information

• Parts replacement information

• Functional test records

• Road-test records

• Vehicle photographs

• Video inspection records

• Vehicle identification information

• Final verification information

These records support internal quality management and provide overseas buyers with additional evidence of vehicle condition and preparation.

For remote purchases, photographs, videos and vehicle-specific records are particularly useful because buyers may not inspect the truck in person before shipment.

Quality Control for Batch Orders

For multi-unit fleet orders, consistency becomes particularly important.

Vehicles may share the same model and specification while still having different mechanical conditions.

Qingdao Alston Motors therefore combines common order standards with individual vehicle inspection.

Batch verification may check consistency in:

• Truck model

• Engine or horsepower specification

• Drive configuration

• Steering position

• Tire requirements

• Cargo-body dimensions

• Tank or mixer configuration

• Repainting

• Customer-requested equipment

• Identification information

At the same time, each truck is evaluated according to its own mechanical and structural condition.

This approach helps maintain a consistent fleet specification without assuming that every used vehicle requires exactly the same refurbishment work.

Quality Control for Demanding Operating Conditions

Many refurbished HOWO trucks are prepared for mining, construction, infrastructure, logistics and heavy-load transport applications.

These environments may involve rough roads, dust, high temperatures, repeated loading, long working hours and limited access to specialized workshops.

For these applications, greater attention is placed on systems such as:

• Chassis

• Axles

• Suspension

• Drivetrain

• Cooling system

• Brakes

• Hydraulics

• Tires

• Working equipment

• Maintenance accessibility

Quality control cannot eliminate future wear or operating risk, but it can help identify existing problems and verify completed preparation before export.

Relationship Between Quality Control and Refurbishment

Quality Control is one part of a wider vehicle preparation process.

The company’s technical workflow can be understood as:

Vehicle Selection → Initial Inspection → Refurbishment → Functional Verification → Road Test → Final Pre-Shipment Check

The detailed mechanical repair, structural refurbishment, painting and upper-body work are carried out through the company’s Production Line.

Quality Control focuses on inspecting and verifying the completed vehicle.

This separation helps prevent refurbishment work from being treated as automatically accepted without further inspection.

Support After Delivery

Quality records can also provide a useful reference for future maintenance and technical communication after delivery.

Qingdao Alston Motors can provide spare parts assistance, technical consultation, maintenance guidance and other support according to customer requirements.

Detailed information about spare parts, export support and after-sales services is available through the company’s Services section.
