High pressure hydraulic oil lines and Jumbo drill rig drifter (rock drill) units. The ultra flexible and tough construction improves service life in applications where the outside cover of the hose is subject to bending, abrasion and rockfall that may cause premature failure of standard hoses.
TUBE: Black, oil resistant synthetic rubber.
REINFORCEMENT: Four alternating layers of spiralled high tensile steel wire.
COVER: DIEHARD™ Black, oil and extra abrasion resistant synthetic rubber. Flame Resistant, Anti-Static (FRAS) & MSHA compliant. Embossed layline for positive, permanent identification. No skiving required with T7000 Series Crimp Couplings.
Meets or Exceeds the Performance Requirements of:
EN 856 Type 4SH, ISO 3862 Type 4SH.
FEATURES: The ultra flexibility combined with very high abrasion resistant properties of the hose cover provides the necessary attributes for drifter (rock drill) unit assemblies. Combined with the extra high working pressures and excellent impulse life, D4000D DRIFTER provides increased service life and minimises Jumbo equipment downtime.
FRAS – FLAME RESISTANCE AND ANTI-STATIC: DIEHARD™ ™ complies with Flame Resistant and Electrical Resistance (Anti-Static) requirements of Australian Standard AS 2660 and Methods of Test AS 1180.10B and 13A. Meets Flame Resistant Designation “U.S. MSHA” of the US Department of Labor, Mine Safety and Health Administration.
TEMPERATURE RANGE: From -40°C to +121°C (-40°F to +250°F).
