Uzbek Construction Company Purchases 4-Axle Rear Dump Semi-Trailer from Global Diamond

4-Axle Rear Dump Semi-Trailer for Sale in Uzbekistan – Boosting Construction Efficiency in Central Asia
A fast-growing construction and aggregate supply company from Tashkent, Uzbekistan, recently visited Shandong Global Diamond Automobile Technology Co., Ltd. to inspect our 4-axle rear dump semi trailer. The customer needed a reliable, high-capacity solution for transporting sand, gravel, and crushed stone across various infrastructure projects in the Fergana Valley and surrounding regions. After a detailed factory tour, load testing, and technical negotiations, the customer signed a purchase agreement for multiple 4-axle rear dump trailers on site.
Our 4-axle rear dump semi-trailer has become one of the best-selling products in Central Asia. Its combination of high payload capacity, robust construction, and fast unloading cycle makes it the preferred choice for mining, quarry, and road construction operations across Uzbekistan, Kazakhstan, and Tajikistan.
Optimized Design for Central Asian Road and Site Conditions
The 4-axle rear dump trailer features a high-strength steel dump body with a U-shaped cross-section that minimizes material residue and ensures complete discharge. The body is manufactured using automatic submerged-arc welding, with floor thickness of 8mm and side walls of 6mm – capable of handling abrasive materials like river gravel and crushed limestone without premature wear.
The trailer’s 4-axle configuration distributes the load evenly across all wheels, reducing ground pressure and complying with regional weight regulations. Each axle is rated at 13 tons, giving the trailer a legal payload capacity of 40-45 tons, depending on local road limits. This capacity matches perfectly with the customer’s fleet of HOWO 6×4 tractors.
The hydraulic tipping system uses dual telescopic cylinders that lift the front of the body to a 50-degree angle. The operator can complete a full dump cycle in under 60 seconds, significantly improving job site productivity.
High-Efficiency Hydraulic System and Reliable Components
The rear dump semi-trailer is equipped with a premium hydraulic system featuring:
– Italian-made hydraulic pump and control valve
– Two-stage telescopic cylinder with anti-fall safety lock
– Large-capacity hydraulic oil tank with return filter
– WABCO pneumatic control system for smooth engagement
These components ensure fast, stable lifting even under full load. The system includes an automatic safety valve that prevents accidental lowering during maintenance or transport.
The trailer also comes standard with ABS braking system, spring parking brakes, and dual-line pneumatic braking compatible with most European and Asian tractor units. LED lighting and reflective markings improve visibility and safety during night operations.
Heavy-Duty Chassis and Suspension
Understanding the challenging road conditions in Central Asia – including unpaved mining roads and seasonal potholes – our engineers reinforced the chassis with high-tensile Q355 steel. The main beam uses a 25mm top flange and 14mm middle flange, welded with continuous robotic arcs for maximum fatigue resistance.
The mechanical suspension uses 10-leaf springs (13mm thick, 90mm wide) with equalizer beams for improved articulation. This setup absorbs shocks effectively while maintaining stability on uneven terrain. Heavy-duty 12.00R20 tires provide excellent traction and puncture resistance.
Excellent Corrosion Protection and Long Service Life
The entire trailer chassis undergoes shot blasting to remove rust and mill scale, followed by one coat of epoxy primer and two coats of polyurethane top paint. This coating system provides outstanding resistance to humidity, road salts, and chemical corrosion – tested to last 5+ years in harsh environments.
The dump body interior receives a smooth, wear-resistant coating that prevents material adhesion and makes cleaning quick and easy. The customer appreciated this feature, as it reduces downtime between different material hauls.
Customer Feedback and Future Cooperation
After taking delivery of the first batch of three 4-axle rear dump trailers, the Uzbek customer operated them for two months on a major highway reconstruction project. The fleet manager reported:
- 98.5% mechanical availability – No unscheduled downtime
- 20% faster cycle time compared to their older 3-axle trailers
- Zero structural issues – The reinforced frame handled 45-ton loads without deformation
- Positive driver feedback – Stable handling and smooth hydraulic operation
“The 4-axle rear dump trailers from Global Diamond have exceeded our expectations,” said the company’s equipment director. “We are now placing a repeat order for five more units to support our new quarry development.”
