Shandong Wantong Hydraulics, leveraging its technological expertise in special hydraulic cylinders, has successfully developed high-performance anchoring and supporting hydraulic cylinders, providing reliable power support for modern mining machinery.

The anchoring hydraulic cylinder adopts a dual-cylinder linkage design. Through a strip-shaped positioning plate and guide rail system, it achieves precise control of the anchor drilling machine's position. The product uses a special alloy steel formula and "ultra-hard plating composite processing technology," resulting in a piston rod surface hardness of HRC55 or higher, increasing wear resistance by 50%. Multi-level pressure adaptive sealing technology effectively reduces starting force by 30%, avoids "crawling," and ensures precise and stable support operations.

The rear support hydraulic cylinder uses finite element analysis to optimize its structure, achieving a 50-ton support force within a compact space of 180mm in diameter. The product is equipped with a pressure adaptive system that automatically adjusts the support force according to the hardness of the bottom plate, improving the stability of the mining machine by 40%. A three-level protection design effectively prevents coal and rock powder from entering, with a salt spray test exceeding 1000 hours, adapting to harsh underground environments.

These two types of hydraulic cylinders from Wantong Hydraulics have been successfully integrated into the combined anchor drilling and roadheader machines of Zhengzhou Coal Machinery and Shandong Energy Group. In applications at the Panjiang mine in Guizhou, the anchoring hydraulic cylinder enabled single-arm equipment to perform anchoring construction in complex locations; in the Yancoal Black Panther project, the rear support hydraulic cylinder effectively solved the "sinking" problem of heavy-duty mining machines.

The company is actively promoting the intelligent upgrading of its products, integrating sensors to achieve real-time monitoring and remote diagnosis. In the future, it will continue to optimize electro-hydraulic fusion technology to provide more reliable hydraulic solutions for deep mining.
