Multi-cylinder collaborative breakthrough: Wantong Hydraulic's hydraulic telescopic cylinder system tailored for large-scale applications

Recently, Shandong Wantong Hydraulic Co., Ltd. (hereinafter referred to as "Wantong Hydraulic") launched a brand-new hydraulic telescopic cylinder system. Featuring "multi-cylinder synchronous extension and precise control" as its core advantages, the system is widely compatible with applications such as bridge maintenance platforms, wind power installation equipment, and large-scale stage lifting mechanisms, filling a critical technological gap in China for the synchronized extension of multiple cylinders in large-scale equipment.

According to the head of Wantong Hydraulic Research & Development Center, the hydraulic telescopic cylinder system consists of multiple telescopic cylinders, a synchronous control unit, and a hydraulic power source. The telescopic cylinders feature a multi-stage design, enabling a maximum extension stroke of up to three meters, while the rated thrust of each individual cylinder covers applications ranging from small to medium-sized equipment. The synchronous control unit employs electro-hydraulic proportional valves, ensuring extremely precise synchronization among multiple cylinders—perfectly meeting the horizontal lifting requirements of large-scale platforms. Additionally, the system is equipped with built-in pressure sensors and position-monitoring modules, allowing real-time tracking of the cylinder’s extension status and automatically triggering an emergency stop in case of any abnormalities. Furthermore, the system can be customized to accommodate specific customer needs, offering flexibility in terms of the number of cylinders, extension stroke length, and control methods, making it suitable for a wide variety of large-scale operational scenarios.

Enterprise Strength: System-Level R&D and Testing Capabilities

As a nationally recognized "Little Giant" enterprise specializing in niche, specialized, and innovative technologies, Wantong Hydraulics boasts a dedicated R&D team for hydraulic telescopic cylinder systems. The company possesses end-to-end development capabilities, spanning everything from cylinder design to control system programming, and has already secured multiple related patents. To ensure superior performance, Wantong has established a system-level testing platform that can simulate real-world operational scenarios such as bridge maintenance and wind turbine installation. This platform enables the company to conduct rigorous, multi-stage tests—including synchronized extension-retraction tests, load tests, and emergency stop tests—to verify that the system operates reliably across a wide range of temperatures, from extremely cold to high-heat environments. Leveraging its "flexible hydraulic system production line," Wantong Hydraulics can meet the customized procurement needs of large-scale engineering projects with an annual production capacity that ensures timely delivery and shorter lead times for tailored solutions.

Market Breakthrough: Large-Scale Engineering Applications Gain Recognition

In a bridge maintenance project in Zhejiang, the inspection platform equipped with Wantong Hydraulic's hydraulic telescopic cylinder system has successfully completed maintenance tasks on several major bridges spanning rivers. The platform achieves exceptionally high lifting and lowering precision through synchronized control of multiple telescopic cylinders, significantly boosting efficiency compared to traditional manual adjustments—and all this while ensuring complete safety throughout the operation. "Bridge inspections demand utmost stability from the platform, and Wantong's multi-cylinder collaborative control system allows us to perform high-altitude work more safely and efficiently," said the project leader. Additionally, the product has also been deployed at a wind farm in Gansu Province, where it is used to adjust the extension and retraction of internal installation platforms within wind turbine towers, perfectly meeting the operational needs of the tower's confined spaces.

The Marketing Director of Wantong Hydraulics stated that as large-scale engineering equipment evolves toward "intelligent and precision-based" solutions, the demand for hydraulic telescopic cylinder systems will continue to grow. Moving forward, the company plans to develop a 5G-enabled, remotely controlled hydraulic telescopic cylinder system tailored for unmanned operation scenarios.
