In the mining transportation field, heavy-duty mining trucks face extremely harsh working environments, placing extremely high demands on suspension systems. Shandong Wantong Hydraulic Co., Ltd., with its deep technical accumulation and continuous innovation, has successfully developed a heavy-duty mining truck air-oil suspension, providing solid support for the stable operation and efficient operation of mining trucks.

Technology Leading, Performance Excellence

The heavy-duty mining truck air-oil suspension produced by the company has high load-bearing capacity and excellent shock absorption performance. Its air-oil suspension system uses gas as the elastic medium and liquid as the force transmission medium, which can effectively absorb road impact energy and ensure the smooth and stable driving of the vehicle when fully loaded and unloaded. The product adopts core technologies such as high and low pressure two-stage air chamber matching design technology under large-span load changes and accumulator dual-air chamber technology, which not only improves load-bearing capacity and stability, but also significantly enhances driving comfort and safety. In addition, the company's newly developed new active control air-oil spring has won the Shandong Provincial Science and Technology Progress Award, and some of its performance far exceeds industry standards, such as the neutral salt spray test of piston rod corrosion resistance can reach 360 hours, while the industry standard is usually 72 hours.

Customized Service, Wide Adaptability

Shandong Wantong Hydraulic provides customized heavy-duty mining truck air-oil suspension solutions for different customer needs. The company works closely with主机厂 (OEMs), actively participating in the test runs of new models and new structures to ensure that the products can accurately match the actual working conditions of various mining trucks. Its products have been widely used in dump trucks from internationally renowned brands such as American Caterpillar, Japanese Komatsu, American Terex, and Belarusian BelAZ, and are gradually increasing their penetration rate in the domestic market, winning the high trust of customers at home and abroad.

R&D Driven, Continuous Breakthrough

As a national high-tech enterprise and a specialized and new "small giant", Shandong Wantong Hydraulic always takes technological innovation as its core driving force. The company has established industry-university-research cooperation with many well-known universities, focusing on the cutting-edge research and application of hydraulic technology. In recent years, the company has made a series of breakthroughs in the field of air-oil suspension, and its products have gradually upgraded from single front axle air-oil suspension to full-vehicle air-oil suspension system, further improving the comprehensive performance of mining trucks and setting a new benchmark for the development of mining truck suspension systems.

Looking to the Future, Expanding Applications

With the intelligent and green development of mining equipment, Shandong Wantong Hydraulic is actively deploying the forefront of the industry. The air-oil suspension developed by the company has been successfully applied to unmanned driverless new energy wide-body mining trucks, demonstrating its capabilities in the field of intelligence. In addition, the company is also continuously exploring green technologies such as pure water hydraulic cylinders to meet the market demand for environmentally friendly products. In the future, Wantong Hydraulic will continue to cultivate the field of air-oil suspension and expand its applications in the markets of heavy trucks, semi-trailers, special vehicles, etc., to provide customers with more efficient and environmentally friendly solutions.
