WANTONG Hydraulics FC Multi-Stage Double-Acting Telescopic Cylinder Now Available—Empowering Long-Stroke Engineering Equipment for High-Efficiency Operations

Recently, Wantong Hydraulic Co., Ltd., a leading enterprise in China's hydraulic industry (hereinafter referred to as "Wantong Hydraulic"), officially launched its new FC multi-stage, double-acting telescopic cylinder. Designed specifically for long-stroke lifting applications, this cutting-edge hydraulic component boasts core competitive advantages such as "multi-segment stroke adaptation, smooth bidirectional power delivery, and exceptional durability across all operating conditions." It precisely meets the operational needs of engineering lifting machinery, aerial work platforms, specialized transportation equipment, and other applications, further enhancing Wantong Hydraulic's product portfolio in the long-stroke hydraulic segment. This innovation provides critical support for upgrading engineering equipment toward greater flexibility and enhanced safety.

In scenarios such as bridge construction, high-altitude maintenance, and heavy-load handling, engineering equipment frequently needs to perform long-stroke lifting and lowering operations: aerial work platforms must smoothly deliver their work platforms to heights of dozens of meters; engineering cranes require precise control over boom extension and retraction to adjust the working radius; and specialized transport vehicles rely on multi-stage lifting mechanisms to tilt and unload cargo. These applications place stringent demands on hydraulic cylinders regarding "stroke coverage range, extension-synchronization accuracy, and stable bidirectional power output." Traditional long-stroke cylinders often encounter challenges such as "limited single-stage stroke requiring frequent adjustments, multi-stage extension delays that easily cause equipment instability, and insufficient power during the lowering phase, making speed control difficult." These issues not only compromise operational efficiency but also pose safety risks due to unstable movements, effectively becoming a critical bottleneck hindering the performance improvement of long-stroke equipment.

Addressing the industry's pain points, Wonton Hydraulics' R&D team leveraged over a decade of expertise in heavy equipment hydraulic technology, collaborating closely with engineering equipment manufacturers to conduct in-depth scenario-based research. With the development goals of "flexible stroke adaptation and bidirectional stability control," they launched a focused technical initiative on the FC multi-stage, double-acting telescopic cylinder. This newly released product achieves breakthroughs across three core technological dimensions: First, it innovatively adopts a modular, multi-stage cylinder barrel design, allowing precise control over the extension and retraction sequence as well as stroke ratios for each segment. This flexibility enables the cylinder to seamlessly meet diverse long-stroke requirements—eliminating the need for frequent oil cylinder replacements—and making it suitable for a wide range of applications, including high-altitude operations, lifting, and loading/unloading tasks, thereby significantly enhancing equipment versatility. Second, the product optimizes its double-acting power transmission mechanism by incorporating advanced pressure compensation technology in both extension and retraction phases, effectively resolving the common issue found in traditional products—strong extension but weak retraction. This ensures smooth operation throughout the entire cycle, from lifting to lowering, while minimizing the risk of equipment instability or shaking. Finally, the cylinder features an upgraded high-strength structure and enhanced protection system. The cylinder barrel is crafted from an integrated, fatigue-resistant alloy material, with a surface treated through multiple layers of wear- and corrosion-resistant coatings. Additionally, the sealing components are made from specialized materials that offer exceptional resistance to both extreme temperatures and impact forces. As a result, the product can confidently handle harsh environmental conditions commonly encountered in engineering scenarios—such as dust, mud, water, and alternating high/low temperatures—thereby extending its reliable operational lifespan.

"To ensure the product is perfectly suited for a variety of long-stroke applications, we’ve collaborated with multiple equipment manufacturers to conduct real-machine testing—ranging from high-altitude maintenance operations at 20 meters down to the tilted unloading of heavy-duty cargo—comprehensively verifying the cylinder’s reliability under different strokes and varying load conditions." According to the head of the Hydraulic Business Division at Wantong Hydraulic Engineering Equipment, the new product not only covers mainstream long-stroke equipment specifications but can also be customized to meet specific equipment design requirements, allowing for tailored cylinder segment numbers and stroke parameters—enabling a precise "one-equipment, one-solution" approach.

Currently, Wantong Hydraulics' FC multi-stage, double-acting telescopic cylinder has entered the stage of mass production and market promotion. The first batch of collaborative partnerships already covers several domestic manufacturers of engineering lifting machinery and aerial work equipment. Meanwhile, some of the equipment equipped with this cylinder has already been put into use in scenarios such as bridge construction, urban high-altitude maintenance operations, and heavy-duty logistics parks. Based on feedback from real-world applications, equipment fitted with the new product demonstrates significantly improved efficiency during long-stroke operations, along with markedly enhanced smoothness and stability in its telescoping movements. Additionally, the number of downtime repairs caused by cylinder-related issues has decreased substantially—resulting in lower operational and maintenance costs for the equipment, while also providing robust assurance for job-site safety. As a result, the product has earned dual recognition from both equipment manufacturers and end-users.

As the first domestic enterprise in the hydraulic cylinder sector to be listed on the STAR Market, Wantong Hydraulics has consistently pursued a strategic direction centered on "empowering key industries through technological innovation." From mining equipment and logistics vehicles to engineering lifting applications, the company continues to build a cross-industry ecosystem of hydraulic products. Looking ahead, Wantong Hydraulics will further deepen the technological evolution of its FC multi-stage, double-acting telescopic cylinders, exploring seamless integration with intelligent control systems for engineering equipment. Additionally, the company will develop customized solutions tailored for specialized scenarios such as ultra-high-altitude operations and handling extremely heavy loads, injecting even more "Wantong Hydraulics power" into the industry's transformation toward greater efficiency, safety, and intelligence.
