Deep-well support breakthrough: Dual-Telescoping Columns Address Long-Stroke Requirements

The double-acting hydraulic pillar is made from a composite alloy steel material combining 27SiMn and 42CrMo. Both the inner and outer cylinders undergo integral forging followed by precision machining, resulting in exceptionally high compressive strength. This design enables the pillar to handle working pressures ranging from medium-to-high to high-pressure applications, making it ideal for large- and medium-sized mining operations in deep shafts with significant extraction heights. The pillar features a dual wear-resistant treatment: "chrome-plated outer cylinder + laser-clad inner cylinder," significantly enhancing its resistance to corrosion and abrasion compared to single-acting pillars. Additionally, optimized layouts of the two-speed locking mechanism and sealing components effectively address synchronization issues and leakage concerns during the two-stage extension process, dramatically extending the product's service life. Furthermore, the product supports a wide range of cylinder diameters and maximum extension strokes, catering to the diverse height requirements of various deep-shaft mines.

Wantong Hydraulics’ two types of cylinders precisely meet the diverse needs of various scenarios.

The multi-stage hydraulic cylinder recently launched by Wantong Hydraulics focuses on the core requirements of “long stroke and high thrust”: The cylinder body is made from 42CrMo alloy steel processed via cold-drawing, and features a multi-section telescopic design. A single cylinder can achieve a maximum stroke of up to 3,000 mm, with rated thrust ranging from 50 to 300 tons. Specifically, the 120-ton multi-stage cylinder customized for waste compaction equipment incorporates a built-in buffering device and advanced anti-leakage sealing technology, ensuring stable operating pressure between 18 and 22 MPa during compaction operations. Its continuous-operation failure rate is below 0.5%, and its service life is 40% longer than that of comparable industry products. Meanwhile, the telescopic hydraulic cylinder emphasizes the characteristics of “lightweight and rapid response.” Its cylinder body adopts a composite structure combining high-strength aluminum alloy with special steel materials, reducing weight by 25% compared to conventional products and increasing the telescoping response speed by 30%. It is ideally suited for applications such as agricultural machinery harvesting arms and positioning mechanisms in mining equipment, with a minimum telescoping radius as low as 150 mm, perfectly meeting the demands of operations in confined spaces.
