Mining Truck Anatomy: The Hoses That Brake, Steer, and Dump

Mining trucks operate in some of the toughest environments, carrying heavy loads and enduring extreme conditions. The reliability of these massive machines depends heavily on several key systems, with the brake, steering, and dump circuits being among the most critical. This paper delves into the specific hoses that keep these circuits functioning at their best.

Given the immense weight these trucks carry, the brake system must be robust, reliable, and able to operate under extreme conditions.

H280 Brake Hose
This two-wire braided hose stands out in the brake circuit, exceeding EN857 Type 2SC specifications. Its exceptional flexibility and temperature resistance make it ideal for the high-pressure demands of brake systems.
  • Weatherhead H180 Hose:
H180 Hose
Cost-effective single-wire hose exceeding EN857 Type 1SC, suitable where two-wire isn’t required. Great for targeted savings without performance loss.

Power Steering System

The power steering system reduces driver effort in low-speed maneuvers. In addition to the H280 and H180 hoses, the following are used:

H430 Hose
R12 four-spiral hose ideal for high-pressure steering systems.
  • Weatherhead GH100 Hose

Dump cylinders lift and lower the truck bed. The H430 hose is reused here, along with:

  • Weatherhead H600 Hose
H600 Hose
R15 spiral hose with tight bend radius for confined installs.
