HAW Expands Range of Intertraco Hydraulic Hose
The new additions are the Intertraco 4ST and 4ST+, each with a 4-wire spiral, and the 6ST consisting of a 6-wire spiral.
- The 4ST is designed for high-pressure hydraulic systems, for use with mineral and biological hydraulic oils, polyglycol base oils, water-oil emulsions and water
- Both the 4ST+ and 6ST variants have the same features, but for high-pressure hydraulic systems with extreme high pressure peaks
Used mainly on earth moving machines and underground mining machines, each of the hoses have a hydraulic oil temperature range of -40° to 121° C, with occasional peaks up to 125° C.
The hoses are made of synthetic rubber tube, either 4- or 6-wire spirals, and include an MSHA flame retardant-approved abrasion-resistant synthetic rubber cover.
Internal hose diameter on the 4ST range is from 5/8” to 2” with working pressure ranging from 3 600 to 5 000 psi and bend radius from 100 to 315 mm. The 4ST+ has internal hose diameter ranging from 3/8” to 1.1/4”, working pressure varying from 6 000 to 6 500 psi and bend radius from 80 to 250 mm. Internal hose diameter on the 6ST measures from 1.1/4” to 2”, working pressure is from 6 000 to 6 500 psi, while the bend radius is from 260 to 395 mm.
Intertraco hydraulic hoses are available from HAW and Hytec branches throughout South Africa.
