Hydraulic Hose 290013003152 is a critical hydraulic transmission component exclusively designed for Hydraulic Rock Drills. It excels in harsh mining environments—for instance, underground ore mines, hard rock quarries, tunnel construction sites and dusty drilling areas.
These settings pose unique challenges for hydraulic hoses: frequent pressure fluctuations, continuous vibration (up to 30G), abrasive rock dust, and temperature swings. These issues often cause hose leakage, wear, or kinking, leading to hydraulic system failures and costly downtime. Yet, Hydraulic Hose 290013003152 maintains uncompromised performance under all these harsh conditions. In fact, it directly addresses five core pain points that plague mining operations.
First, its NBR inner tube + 4-layer steel wire braid reinforcement withstands 35MPa working pressure and 140MPa burst pressure. This eliminates leakage or bursting caused by pressure spikes in drill hydraulic systems. Second, the anti-wear outer cover (Shore A 70 hardness) resists scraping from rock edges and dust abrasion. Consequently, it extends service life by 120% compared to standard hydraulic hoses. Third, its anti-kink design (minimum bending radius ≥120mm) adapts to tight installation spaces in drill equipment. Likewise, this avoids flow restriction and internal damage during drill movement.
Fourth, the NBR inner tube is oil-resistant and compatible with ISO VG 32/46 hydraulic oils. Above all, this prevents tube swelling and ensures consistent oil transmission for long-term use. Fifth, the wide temperature adaptability (-30°C~110°C) ensures reliable operation in cold high-altitude mines and hot underground drilling environments. On top of that, the steel wire braid resists rust and corrosion from moisture, enhancing durability in humid mining sites.
Unlike ordinary hydraulic hoses, this model is engineered for Hydraulic Rock Drills’ dynamic working conditions. To elaborate, the 4-layer braid balances pressure resistance and flexibility, while the anti-kink structure fits drill equipment’s compact layout. Thus, it outperforms generic hoses in service life by 130%, significantly reducing replacement-related downtime.
Our manufacturing team uses precision extrusion + braiding technology for uniform tube thickness. Furthermore, each unit undergoes 35MPa pressure testing (20 minutes) and leak verification. Additionally, the hose undergoes 80,000-cycle bending trials to ensure no fatigue damage.
Notably, it adapts to extreme temperatures from -30°C (high-altitude cold regions) to 110°C (high-load drill systems). Moreover, it passes 250-hour salt spray tests with no braid rust or outer layer peeling. In addition, it endures 4,000-hour oil immersion trials without performance degradation.
The hose’s standard BSPP fittings integrate seamlessly with mainstream Hydraulic Rock Drill hydraulic systems. It requires no special adapters for installation. As a result, maintenance teams can complete replacement in 12 minutes using standard tools.
Our quality team conducts strict ISO 9001 verification for every unit. We perform pressure resistance tests, wear resistance inspections, bending fatigue trials and corrosion resistance verification. Importantly, it complies with ISO 1436-1 international hydraulic hose standards.
Compatible with top Hydraulic Rock Drill brands, it serves as a direct OEM replacement. Thanks to its reliability, it reduces hose-related failure rates by 92%. Additionally, backed by a 12-month warranty, it lowers annual maintenance costs by 55%.
It not only ensures stable hydraulic oil transmission but also extends the service life of drill hydraulic systems by 80%. Overall, Hydraulic Hose 290013003152 delivers cost-effective, reliable performance for long-term mining operations. Beyond that, it minimizes downtime caused by hose failures, maximizing operational efficiency and project profitability.
