Hengshui Zhehan Rubber & Plastic Products Co., Ltd. specialize in hydraulic rubber hose R&D and production across five major equipment categories: construction, agriculture, automotive, mining, and marine. All hoses are manufactured to ISO, EN, and SAE standards, and we supply both standardized and application-specific solutions to international buyers.
This is an extra-high-pressure, heavy-duty burst-proof hose developed specifically for the brutal conditions of underground mines and surface open-pit operations.
How can a hydraulic hose eliminate the risks of high-pressure burst, acid and alkali corrosion, and abrasive wear?
The answer lies in targeted design. Our mining-grade hoses directly address these failure points to provide a core layer of safety protection for mining equipment.

The Hydraulic Hoses For Mining Equipment is built around an extra-thick multi-layer steel wire spiral reinforcement. This construction delivers a working pressure of up to 55 MPa and a burst pressure that considerably exceeds standard requirements, providing high resistance to pressure surges and preventing catastrophic failures under heavy loads. The outer cover uses a specially formulated rubber compound that resists abrasion, acids, and alkalis. It can take on aggressive mine water, chemical corrosion, sharp rock debris, humidity, dust, and fire hazards — and it incorporates anti-static and flame-retardant properties essential for underground safety. Impulse testing verifies a service life of over 300,000 cycles, helping mines reduce unscheduled downtime and maintenance costs.
These Hydraulic Hoses For Mining Equipment connect into roadheaders, shearers, armored face conveyors, mining dump trucks, roof support shields, hydraulic drilling rigs, and other heavy machinery in coal, iron, and non-ferrous metal mines. They are used in underground extraction, open-pit mining, and mine material transport — wherever high-pressure hydraulic power must perform reliably in hazardous environments.
