Why Mining Operations Demand
Specialized Hydraulic Supply

Mining equipment operates at pressures, temperatures, and duty cycles that standard industrial supply houses are not prepared for. When a haul truck is blocked on a haul road or a longwall face stops moving, the cost is not measured in hundreds, it is measured in tens of thousands per hour.

We build hose assemblies rated to 60,000 PSI, stock flame-retardant and emulsion-compatible components for underground applications, and maintain the inventory depth to get critical parts to your operation the same day. Mine-site supply is a specialty, not an afterthought.

Extreme Conditions

High pressure, constant vibration, abrasive environments, and temperature extremes demand components built to a higher standard.

Non-Stop Operations

Mining runs 24/7. Hydraulic component failures at 3 AM need the same response as failures at noon.

High Failure Cost

A blocked haul road or stopped longwall face can cost more per hour than the entire hydraulic system being repaired.

Built for Mining

We stock products specifically rated for mining, not repurposed general industrial supply.

What We Provide for Mining

Six capabilities built for the real demands of surface, underground, and drill rig mining operations.

Underground Mining Hydraulics

Underground mining environments place extreme demands on hydraulic components, confined spaces, high humidity, constant vibration, and the need for absolute reliability where service calls are difficult and costly.

  • High-pressure hose rated for underground mining conditions
  • Flame-retardant and fire-resistant hose assemblies
  • Compact routing configurations for confined machine bays
  • Stainless fittings for corrosion resistance in wet environments
  • Emergency breakdown support for underground equipment

Surface Mining Equipment

Surface mining operations run some of the largest hydraulic equipment in any industry. We supply hose assemblies and fittings for draglines, shovels, haul trucks, and surface drill rigs.

  • Large-bore hose assemblies for high-volume surface equipment
  • Haul truck steering and suspension circuit hose
  • Hydraulic shovel and dragline cylinder assemblies
  • Dust and UV-resistant outer jacket hose for exposed runs
  • Komatsu, Caterpillar, Hitachi, and Liebherr compatible parts

Drill Rig Hose Assemblies

Drill rigs operate under some of the most demanding hydraulic conditions, high pressure, constant motion, and exposure to abrasive environments. We build hose assemblies specifically rated for drill rig feed, rotation, and pull-down circuits.

  • High-pressure drill feed cylinder hose assemblies
  • Rotation motor circuit hose and fittings
  • Pull-down and crowd circuit hydraulic components
  • Atlas Copco, Sandvik, Epiroc, and Caterpillar compatible
  • Abrasion-resistant cover hose for drill deck environments

Longwall Mining Systems

Longwall shearer and hydraulic roof support systems are critical to continuous underground coal and mineral production. A single hose failure in a longwall system can halt an entire face.

  • Shearer drum motor and ranging arm hose assemblies
  • Hydraulic roof support leg and advancing cylinder hose
  • Emulsion and water-glycol compatible hose and fittings
  • High-cycle rated assemblies for continuous face operations
  • Emergency face-support hose kits for rapid replacement

Haul Truck Hydraulics

Mining haul trucks are among the most expensive pieces of equipment on any mine site. A hydraulic failure on a 300-ton haul truck doesn't just idle the truck, it can block an entire haul road.

  • Steering cylinder and pump circuit hose assemblies
  • Body hoist cylinder hose and fittings
  • Brake accumulator circuit hydraulic components
  • Caterpillar 793/795, Komatsu 930E, Liebherr T 264 compatible
  • Emergency haul truck hose kits for mine-site rapid response

Emergency Breakdown Response

Mining operations run around the clock, and equipment failures don't wait for day shift. Our emergency breakdown response is staffed 24/7 with the inventory and expertise to get your machines back in service fast.

  • 24/7 emergency hotline, answered by hydraulic specialists
  • Pre-built emergency kits for common mining equipment failures
  • Same-day shipping on in-stock assemblies and fittings
  • Mine-site delivery coordination available
  • Post-incident documentation and root cause analysis support

Products We Stock for Mining

Purpose-selected hydraulic components for the extreme demands of mining equipment and operations.

High-Pressure Mining Hose (60K PSI)

Ultra-high-pressure hose assemblies for drill rigs and hydraulic rock breakers operating at extreme working pressures.

Haul Truck Steering Cylinder Hose

Large-bore, high-pressure hose assemblies for Cat 793/795, Komatsu 930E, and Liebherr haul truck steering circuits.

Drill Rig Feed Cylinder Assemblies

High-cycle, abrasion-resistant hose assemblies for drill rig feed, rotation, and pull-down circuits on surface and underground rigs.

Shearer Drum Motor Hose

Flame-retardant, emulsion-compatible hose assemblies for longwall shearer drum motor and ranging arm circuits.

Hydraulic Roof Support Hose

High-pressure, water-glycol compatible hose and fittings for underground hydraulic roof support leg and advancing systems.

Conveyor Tensioning Cylinder Fittings

Heavy-duty fittings and adapters for hydraulic tensioning systems on mine conveyor belts and drive stations.

Wheel Loader Bucket Cylinder Hose

Replacement hose assemblies for wheel loader lift, tilt, and bucket circuits, Komatsu, Caterpillar, Volvo, and Liebherr.

Mining-Grade ORFS Stainless Fittings

Stainless steel ORFS fittings for high-corrosion underground and wet-mining environments where carbon steel fittings fail prematurely.

Why Mining Operations Choose Hydraulic Hunter

We're not a general industrial supplier who happens to sell hose. We're a specialist who understands what mining equipment demands.

Extreme Pressure Rated

We stock and build hose assemblies rated up to 60,000 PSI for the ultra-high-pressure applications found in drill rigs and mining rock breakers.

Mine-Site Delivery

We coordinate delivery directly to your mine site or surface facility, because driving an hour to a supply house isn't an option when a haul road is blocked.

OEM Spec Compatibility

Our assemblies are built to OEM pressure ratings and dimensions for Komatsu, Caterpillar, Sandvik, Epiroc, and all major mining equipment brands.

24/7 Emergency Team

Mining doesn't stop for shift changes, and neither do we. Our emergency line is staffed around the clock by people who understand mine-site urgency.
