Minerals extraction equipment features heavily in the hydraulic hose replacement and the original equipment manufacturing (OEM) markets.
Wherever ore or coal or precious stones are extracted, gold is sluiced or diamonds and uranium are mined from deep in the Earths crust, hydraulic hoses and tubes carry the hydraulic oil under immense pressure to power the enormous equipment used in the mining process.
As the extraction equipment grows in size and payload, so the hydraulic hose is required to perform at the most extreme of conditions.
The structure of the high pressure and super high-pressure hoses and the ability of the end fittings to maintain a bond with the hose itself is a technology that grows with the constantly evolving systems.
Some applications of the hydraulically powered equipment include,
- Oil and Gas exploration, offshore drill rigs and on-shore drilling.
- Hydraulic fracking and deep well exploration
- Drilling and blasting, quarries and open cut mining for coal and gold and precious stones
- Mobile plant. Haulage equipment, road trucks, huge excavators or mighty draglines and dredging.
- Fixed plant coal loaders, and railway line maintenance,
- Conveyors and Power Stations.
Maintenance and breakdown.
Maintenance can be routine or scheduled maintenance or breakdowns caused by many external factors.
Scheduled maintenance pre-empts the potential life cycle failure. Hoses are rated for numbers of pressure impulses they carry and the operations of equipment on 24/7 can be predetermined as to the point after which the useful operating capacity will decline dramatically. This is the point at which the hose is replaced perhaps with the number of operating hours the primary consideration. Within a particular coal mining activity all of the hoses on the Komatsu haul trucks will be replaced after 8000 operating hours, approx. 15 months of continuous operation.
When hydraulic hoses fail as a consequence of external factors that are largely uncontrollable they very often cause the single machine that has stopped to create backlogs in production or operation for lengthy periods. The result may often be the immense cost of downtime or stoppage until the failed hose and the lost hydraulic fluids can be replaced and the system restarts.
Extreme pressure causes life cycle destruction of the steel and rubber construction,, hoses can be torn from a machine or overworked in a change of bedrock material while hammering, such as in rock quarries that provide our road base and concrete production.
Can exceed bend radius or operate in temperature extremes from outback desert conditions to snow and ice.
Subject to extremes of corrosion as in salt production or oceanic bed dredging or mining.
Operator error can result in a single hose failure or potentially fire or rollover that might cause the need for a complete replacement hydraulic hose set valued often in the 10’s of thousands of dollars.
Quarries and underground mining often happens near major population centres.
In heavy mobile plant field companies/brands such as Caterpillar Komatsu and Hitachi dominate the market with Liebherr and Joy mining.
Other hose types that feature in the mining sector are, pneumatic lines, grease lines for automated lubrication or in fire suppression systems and fixed steel pressure tubing.
In fixed plant many different companies are engaged on production of washeries and conveyors, coal and iron- ore loading and transport.
