Quality Inspection & Testing

Production & Inspection Workflow
1. Frame Stamping & Assembly -> 2. Robot Welding & Cab Alignment -> 3. Cathodic E-Coating -> 4. Powertrain Integration -> 5. ABS & Brake Bench Test -> 6. Water Tightness Rain Test -> 7. 100km Road Dynamic Test

Key Quality Steps
Precision Frame Stamping: High-tensile alloy steel frames are cold-stamped on 6,000-ton hydraulic presses to prevent frame twisting under heavy torsional stress.

Robotic Cab Welding: Cabins are assembled using automated laser-guided welding lines, maintaining dimensional tolerances within +/-0.5 mm.

Cathodic Electrophoretic Paint (E-Coating): Full-submersion electrocoating protects the chassis frame and cab against salt spray corrosion for over 1,000 test hours.

Dyno & Brake Testing: Every unit undergoes roller bench testing to verify engine output curves, transmission shift precision, and WABCO ABS braking balance.

Rain Tightness Testing: Cabs are subjected to a high-pressure water spray shower at 150 kPa for 30 minutes to confirm weather seals before final delivery.

Track Dynamic Testing: Vehicles complete a 100 km test track loop covering steep gradients, rough pavement, and full-load emergency braking sequences.

Customization & Purchasing Options

Engine & Transmission Matching

Select between Weichai WP10/WP12/WP13, Cummins ISX/ISL, or SINOTRUK MC engines matched with FAST or ZF transmissions.

Cabin Layouts

Flat-floor high-roof cabs with dual bunks for long-haul routes, or low-roof single-bunk cabs for regional port shuttle operations.

Axle & Gear Ratios

High-speed gear ratios (3.7 / 4.11) for highway efficiency or high-reduction ratios (4.77 / 5.73) for steep grades and heavy payloads.

Fuel & Range Configurations

Single 400L tanks, dual 800L tanks, or cryogenic LNG / CNG fuel tank installations.

Fleet Telematic

Pre-wired GPS tracking interfaces, CAN-bus data ports, and driver monitoring systems.

Shipping, Delivery & Export

Shipping Method	Description & Suitability	Protection Level
RORO Shipping	Vehicles are driven on and off the vessel. Suitable for fully assembled trucks.	No direct saltwater exposure during normal voyage conditions; protection depends on vessel and stowage arrangements.
Bulk Cargo (Under Deck)	Vehicles are crane-loaded and stowed below deck.	Vehicles are wax-coated and covered with marine tarpaulins for protection against moisture and sea spray.
Flat Rack Container	Chassis-stripped or semi-CKD vehicles are loaded onto 40-ft flat rack containers.	Suitable for oversized cargo and fleet shipments; protective wrapping and securing depend on the shipping arrangement.

Corrosion & Transit Protection
Underbody Marine Waxing: A heavy-duty anti-corrosion wax layer is applied to the frame, axles, steering linkages, and electrical connectors.
Fully Wrapped Cabins: Cabins are sealed with weatherproof shrink film to shield glass, paint, and mirrors during transit.
Customs Document Support: We provide complete Bill of Lading (B/L), Certificate of Origin (Form E, Form A, CO), Commercial Invoice, Packing List, and GCC / ADR inspection certificates.

A: We supply Weichai, Cummins, and SINOTRUK diesel engines ranging from 290 HP to 560 HP. Emission standards range from Euro II/III (for regions without strict emissions laws) to Euro V and Euro VI (for compliant international markets).

Q: Can you manufacture Right-Hand Drive (RHD) tractor trucks?

A: Yes. We manufacture both Left-Hand Drive (LHD) and Right-Hand Drive (RHD) chassis configurations across all 4x2 and 6x4 tractor truck lines.

Q: What is the typical lead time for a fleet order?

A: Standard production lead time is 25 to 35 days after drawing confirmation and deposit receipt. Specialized customizations (such as LNG fuel tanks or custom axle ratios) may require up to 45 days.

Q: How do you handle spare parts supply for overseas buyers?

A: We use standard international components (including WABCO valves, JOST fifth wheels, FAST/ZF gearboxes, and Bosch fuel injection systems). For fleet orders, we provide wearing-part kits (filters, belts, brake shoes) alongside the shipment and offer direct OEM spare parts dispatches via DHL/FedEx or sea freight.

Q: What warranty coverage is provided with the tractor trucks?

A: Our standard warranty covers the core powertrain—engine block, transmission housing, drive axles, and chassis frame—for 12 months or 100,000 kilometers (whichever occurs first).

Q: What shipping methods are available for commercial trucks?

A: We ship via Roll-on/Roll-off (RORO) vessels, dedicated bulk cargo carriers (stowed under deck), or 40ft Flat Rack / Open Top containers depending on port infrastructure and total shipping costs.
