Shandong Wantong Hydraulic Oil and Gas Spring Technology Aids in the Upgrade of European Multi-purpose Transport Vehicles, Competing in the Global High-end Market

In the increasingly competitive global hydraulic equipment market, Shandong Wantong Hydraulic Co., Ltd. (hereinafter referred to as "Wantong Hydraulic") has successfully entered the European multi-purpose vehicle market with its self-developed gas-oil spring technology, becoming a key supplier of core components for suspension systems. This breakthrough not only demonstrates the technological strength of Chinese manufacturing, but also provides innovative solutions for the efficient and intelligent transformation of global engineering vehicles.

Technological Breakthrough: Gas-Oil Spring Performance Leads the Industry

Wantong Hydraulic's gas-oil spring products are one of its "trump card" technologies, mainly used in the suspension systems of mining vehicles and multi-purpose transport vehicles. This product uses gas as the elastic medium and liquid as the force transmission medium, combining buffering and shock absorption with empty/full load height leveling functions. It effectively solves the problems of vehicle stability and durability under complex road conditions. Its **new active control gas-oil spring** has won the Shandong Provincial Science and Technology Progress Award, and its core performance far exceeds industry standards. For example, the piston rod corrosion resistance neutral salt spray test can reach 360 hours, while the industry conventional standard is only 72 hours.

European multi-purpose transport vehicles have extremely high requirements for suspension systems, especially vehicles that quickly switch working modes (such as the conversion between mixer trucks and dump trucks), which need to adapt to different loads and environments in a short time. Wantong Hydraulic's gas-oil springs, through optimized sealing structure and surface treatment technology, have achieved high reliability and long life, perfectly matching the European market's demand for high efficiency and durability.

Adapting to European Needs: Multi-Scenario Applications and Standardized Interfaces

The European transport vehicle market has recently accelerated the promotion of the "one vehicle, multiple uses" concept. For example, the DAUTE brand's quick-change system can complete the switching of mixer truck and dump truck cargo boxes within 5 minutes, and this type of system relies on standardized hydraulic interfaces and efficient suspension devices. Wantong Hydraulic's gas-oil springs, with their modular design, can adapt to the interface standards of different vehicle models, helping vehicles achieve rapid functional conversion. In addition, the high-pressure and intelligent characteristics of its products synergize with the hydraulic drive technologies (such as OptiTrack, Hydraulic Auxiliary Driver) promoted by European truck manufacturers (such as Mercedes-Benz and Renault), further improving vehicle passability under complex road conditions.

Corporate Strength: Innovation-Driven and Global Layout  

As a national-level specialized and new "small giant" enterprise, Wantong Hydraulic has been deeply involved in the hydraulic cylinder field for 20 years, accumulating 61 authorized patents (including 20 invention patents), and has built a core technology system covering cold drawing technology, mirror polishing control, and double-chamber accumulators. The company, through industry-university-research cooperation, jointly develops high-end hydraulic products with universities, and at the same time introduces professional managers and technical personnel to promote process iteration and upgrading.

In terms of international layout, Wantong Hydraulic products have been exported to more than 30 countries and regions, including the United States, Colombia, and Russia. In early 2025, the company revealed that its gas-oil spring devices successfully entered the European supply chain and reached cooperation with several leading transport equipment manufacturers.

Future Outlook: Extending to the High-End of the Industrial Chain  

Wang Wanfa, chairman of Wantong Hydraulic, said that the company will continue to increase R&D investment, focusing on high-pressure and green trends, developing intelligent electronic control hydraulic systems, and further expanding into emerging fields such as wind power and marine engineering. With the help of the capital market, the company plans to establish a technical service center in Europe to strengthen its localized support capabilities and consolidate its leading position in the global hydraulic industry.

In the future, with the growth in demand for multi-purpose transport vehicles, Wantong Hydraulic is expected to continue to "break out" in global competition and lead industry transformation.
