TIefenbach North America

SteckO staple hydraulic hose connectors are the preferred choice used in longwall coal mining operations worldwide. Super SteckO is a high performance staple adaptor. It was introduced to increase essential performance and safety standards to match the advancement of coal mining technology.

Chocks Introduction underground COAL

The chocks were interconnected with hydraulic hoses and connected back to a pumping arrangement in the gate road by a hydraulic fluid reticulation system. The hydraulic fluid used was and still is mostly water with a low concentration of soluble oil partly to assist in lubri ion but mostly to inhibit corrosion.

Uses for Hydraulic Hose - Mining Products

Hydraulic hose are used in a number of industries including coal mining tunnel building petroleum related processes and welding. They allow liquids to be able to transfer at very high pressure safely and securely in hazardous environments. Hose are made from high quality rubber and are heavily insulated which increases their durability whilst being able to direct fluids in at consistent
