Product Features
6×4 drive for heavy trailers
The two rear driving axles give the truck good traction when pulling a loaded trailer. This setup is commonly used when the truck needs to handle both highway transportation and heavier cargo.
01
Rear air suspension
Compared with a conventional leaf-spring setup, rear air suspension is more suitable for customers who spend a lot of time on paved roads. It can also help provide a smoother ride when the trailer is properly loaded.
02
MAN-based power system
The engine uses MAN technology and is paired with a Sinotruk manual transmission. Together with the hydraulic retarder, the setup is suitable for long-distance driving where frequent speed control is needed.
03
90# fifth wheel
The 90# fifth wheel is designed for heavy trailer work and can be used with different types of semi-trailers depending on the customer's transport requirements.
04
Road-oriented configuration
The truck uses a highway-type intake system, standard exhaust system, lightweight wheels and 12R22.5 tires. These details make this configuration more suitable for regular road transportation than purely off-road work.
05
Our Main Products

Besides SITRAK tractors, we also supply HOWO and other heavy-duty trucks, including dump trucks, mixer trucks, tractor units and tank trucks.

Our semi-trailer range includes flatbed trailers, container chassis, low-bed trailers, side wall trailers, dump trailers, cement tank trailers, fuel tankers and car carriers. Truck and trailer configurations can be discussed together if the customer needs a complete transport combination.
After Sales Service
Before the vehicle leaves the factory, we check the main mechanical and electrical systems. The engine, gearbox, axles, brakes, steering system, lights and electrical connections are checked before shipment.
For export orders, we can also provide technical information, spare parts support and basic operating guidance. If the customer needs replacement parts later, we can help confirm the correct model and configuration before shipment.

Packing & Delivery
For truck exports, the shipping method depends mainly on the destination, quantity and port conditions. Bulk vessel and Ro-Ro shipping are commonly used for complete vehicles.
Before loading, the truck is cleaned and prepared for sea transportation. Exposed parts are protected where necessary, and the vehicle is properly secured during loading to reduce movement during the voyage.
We can work with the customer's nominated forwarder or arrange transportation through our logistics partners.
