WanTong Hydraulics Upgrades Technology for Drilling, Anchoring, and Support Cylinders, Paving the Way for Domestic Breakthroughs in Mine Excavation and Support Equipment

Shandong Wantong Hydraulic Co., Ltd.'s independently developed hydraulic cylinder for mining, anchoring, and support systems has become a critical enabler in breaking through technological barriers in core hydraulic components for domestically produced mining equipment, thanks to its exceptional impact resistance and precise synchronous control capabilities. These cylinders are fully compatible with the multi-process operational demands of integrated mining, anchoring, and support machines, delivering stable rated working pressure even under challenging conditions such as high dust levels, heavy load impacts, and complex rock formations in mining environments—while significantly extending continuous, trouble-free operation compared to conventional products. 45% Above, this effectively fills the technological gap in high-end drilling, anchoring, and support hydraulic cylinders domestically. According to Wantong Hydraulics 2025  The first-half financial report revealed that, among its cylinder business for mechanical equipment, the revenue from cylinders used in mining, anchoring, and support systems increased year-on-year by… 70% , driving the company's overall gross margin for cylinder business used in mechanical equipment to remain stable at 27% , becoming one of the core drivers of corporate revenue growth.

For掘锚护 equipment “ Dig -  Anchor -  Protect ”  Facing core operational challenges in synchronized operations—such as high-load impacts, severe dust erosion, and stringent precision requirements for coordinated multi-motion tasks—Wantong Hydraulics has developed “ High-impact resistance -  Strong Sealing -  Precision Collaboration ”  A specialized technical system. In terms of material application, the jacking and anchoring support cylinders feature cylinder bodies crafted from ultra-high-strength alloy forgings, with the base material achieving a tensile strength of up to 1300 MPa Above, paired with the piston rod's surface nano-ceramic -  Chrome-plated composite coating technology enhances wear resistance compared to traditional methods. 55% , capable of meeting the demands for long-term, high-intensity operations under various mining geological conditions, such as hard rock and soft rock.

At the structural design level, the R&D team innovatively adopted “ Level-4 Buffer Energy-Absorbing Structure ” , it features a built-in high-precision pressure and displacement dual-sensor module that continuously captures fluctuations in excavation load and stroke data from support actions, dynamically adjusting the oil circuit’s buffer flow rate to keep the impact vibration during drilling, anchoring, and support operations within a controlled range— 2.2g Within (the industry average is 4.8g ), significantly enhancing equipment operational stability and service life. At the same time, leveraging the company's 2025  Newly added this year 17  This patented technology features cylinders equipped with “ Multi-layered duplex dust- and rock-proof sealing system ” , in mining environments with high dust levels and flying gangue debris, the seals demonstrate a service life that exceeds industry standards by a significant margin. 75% , significantly reducing the frequency and cost of equipment maintenance. Additionally, Wantong Hydraulics 2025  In the first half of the year, we continued to increase R&D investment, with R&D expenses growing by a significant year-on-year increase. 15.93% , we are focusing on advancing the development of an intelligent collaborative control module for excavating, anchoring, and supporting hydraulic cylinders. Currently, we have achieved synchronized error control within a narrow margin—less than —for the multiple actions involving excavation, anchoring, and support cylinders. ±0.3mm Within this framework, it provides critical technological support for the intelligent control of mining and anchoring equipment. ​

For a long time, the high-end mining and anchoring support cylinder market has been dominated by international brands such as Germany's Bosch Rexroth and Sweden's Höganäs, with imported products costing significantly more to procure than domestically produced ones. 45%-65% , and the delivery cycle can be as long as 5-7 Months have severely constrained the technological upgrades and cost control of domestically produced mining, anchoring, and support equipment. Through continuous technological innovation, Wantong Hydraulics has achieved comprehensive breakthroughs in key performance indicators for its hydraulic cylinders used in mining, anchoring, and support systems—specifically, ensuring reliable continuous operation for up to 98.8% (On par with international top-tier brands), delivery lead time reduced to⏤ 30–40 Heaven, the after-sales service response time is kept within 24  Within hours, gradually break the monopoly pattern of international brands. ​

Industry data shows that WanTong Hydraulics' market share in China's mid-to-large-sized oil cylinder market for mining, anchoring, and support applications has now risen to 35% , Compared to 2023  Achieving double-digit growth this year, we have become a core supplier of hydraulic cylinders for domestically produced mining and anchoring equipment. Meanwhile, the core technologies—such as high-pressure shock resistance and multi-action collaborative control—developed through our R&D efforts in cylinders for mining and anchoring applications are gradually being integrated into the company's product lines, including hydraulic components for mining robots and intelligent oil-gas suspension systems. This strategic technology transfer is fostering synergies across product areas, helping us build a robust and innovative portfolio. “ Mining Excavation Support Cylinder + Smart Mine Hydraulic Solutions ”  The product matrix provides end-to-end support for the green and intelligent upgrading of mining equipment. ​

As a leading domestic manufacturer of hydraulic components, Wantong Hydraulics leverages its technological breakthroughs in jacking, anchoring, and support cylinders to drive the advancement of core equipment components for mine excavation and reinforcement in China. “ Import Dependence ”  Towards “ Self-reliant and controllable ”  Transformation. As technological iteration accelerates and market share expands, Wantong Hydraulics' cylinders not only provide critical support for enhancing the performance of domestically produced mining and anchoring equipment, but also mark China's manufacturing prowess in the high-end mining hydraulics sector. “ Following closely ”  Towards “ Leading the way ”  A significant symbol of跨越.
