Mining Trucks Resistors

Engineered for Australian Mining Operations. OEM-Level Performance. Aftermarket Flexibility.

Our braking resistor systems are designed for heavy-duty mining haul trucks operating in Australia’s open-pit environments.

Supporting diesel-electric, hybrid, and battery-electric platforms, our solutions deliver voltage capability up to DC 2200V and power capacity up to 4 × 1200 kW.

We combine platform-level engineering capability with application-ready product configurations — enabling direct replacement, retrofit upgrades, and customized thermal solutions for mining fleets and maintenance providers.

Technology Platforms

High-Voltage Diesel-Electric Platform

Designed for conventional mining haul trucks operating on DC traction systems.

• Voltage range: DC 500V – 2200V
• Continuous high-power dissipation
• Dual and quad resistor configurations
• Suitable for mid-class to ultra-class haul trucks

Typical applications:
108T, 110T, 130T, 150T, 240T and 330T class mining trucks.

Battery-Electric & Hybrid Platform

Optimized for regenerative braking systems in electric and trolley-assist mining trucks.
