In the global supply chain, the truck fifth wheel is not merely a component; it is the critical pivot point that ensures the safety, stability, and efficiency of long-haul transportation. As a premier manufacturer and exporter, we specialize in CE-certified fifth wheels designed to withstand the rigorous demands of Sinotruk HOWO and Shacman tractor units.
Our engineering philosophy revolves around "Zero-Failure Coupling." By utilizing high-tensile forged steel and advanced casting techniques, we provide fifth wheels that offer exceptional load-bearing capacity (D-value performance) and wear resistance, essential for navigating Africa’s rugged terrains and Europe’s high-speed corridors.
Our fifth wheels meet stringent CE certification standards, ensuring legal compliance in EU markets and beyond. This involves rigorous testing for fatigue strength, static load endurance, and automated locking mechanism reliability.
Utilizing 20Mn2 or 40Cr alloy steel, our casting and forging processes guarantee a fifth wheel that can handle vertical loads of up to 25,000kg and D-values exceeding 160kN.
Safety is paramount. Our designs include a secondary safety lock and optional electronic sensors to provide real-time feedback to the driver, preventing accidental uncoupling.
Located in Deyang, Sichuan, Hongkai Auto Trading Co., Ltd. leverages China's most robust heavy-duty automotive supply chain. Our factory integrates R&D, casting, machining, and final assembly under one roof.

Fleet operators in North America and Europe are increasingly demanding "sensor-integrated" fifth wheels to reduce human error and improve telematics data accuracy.
Lightweight fifth wheels are the new trend. By reducing the weight of the coupling device by 15-20% without sacrificing strength, we help fleets improve fuel economy and increase payload capacity.
Global enterprises now prioritize "Local Support + Global Standards." We provide 24-hour technical consultation and have established service points in key regions like Lagos, Nairobi, and Johannesburg.
In the Lagos-Dakar route, our trucks and fifth wheels endure high temperatures and dust. The grease-free liner option on our fifth wheels reduces maintenance time in remote areas.
In Zambia's copper mines, the Sinotruk HOWO 8x4 dumper, coupled with our heavy-duty reinforcement, ensures stability during off-road tilting and extreme load shifts.
The Shacman X3000 series optimized with our 2-inch and 3.5-inch fifth wheels provides the maneuverability needed for tight construction sites in Accra and Nairobi.
Thoroughly understand customers' transportation needs, such as cargo types, routes, and load requirements to recommend the best truck models.
Comprehensive inspection including exterior cleaning, interior finishing, performance debugging, and safety testing before delivery.
24-hour technical consultation and training for drivers to improve skills in operation and maintenance.
A clear, reasonable warranty scope and period, strictly implemented to protect your investment.
"The comfort and fuel efficiency of our Shacman tractor make long hauls from Luanda less tiring. The coupling stability is top-notch."
- Logistics Hub Manager, Angola"Operating in Zambia's mines, we need torque and payload. This dump truck's resilience handles heavy equipment daily."
- Mining Supply Owner, Zambia"Fuel economy exceeded expectations. One of the smartest business decisions for our freight company."
- Emily Johnson, USA"As a mechanic in South Africa, I see many brands. Sinotruk's engine robustness handles our dusty conditions perfectly."
- Fleet Mechanic, JohannesburgA: The size refers to the diameter of the kingpin it accepts. 2-inch (50mm) is standard for most highway freight trailers, while 3.5-inch (90mm) is designed for heavy-duty off-road and mining applications where the vertical load and D-value are significantly higher.
A: While our fifth wheels are designed for durability, regular lubrication of the top plate and locking mechanism is recommended every 5,000-10,000km. We also offer "Low-Maintenance" versions with PE plates that reduce grease requirements.
A: As a verified trading company based in Deyang, we provide full chassis documentation, CE certification, and export certificates for every unit. Our partnership with the original factories ensures 100% genuine components.
A: Yes, we maintain a complete inventory of wearing parts—including jaw kits, locking pins, and wear rings—available for air-freight to any global location within 7-14 days.
