Key features

• Hub-reduction architecture splits the torque path between a central reducer and wheel-end gearing, delivering very high overall ratios without overloading the center gears.
• Ratios from 9.439 up to 30 — short gearing for loaded startability on ramps, haul roads and rough pit floors.
• Rated from 18 t on wide-body mining trucks up to 65–70 t on the HDZ530 for large off-highway haulers.
• Heavier hub and spindle build for continuous duty under dust, shock loads and repeated torque reversals.
• The same HanDe supply chain as on-highway axles, with export service coverage in 20+ countries.

Applications

These axles target off-highway vehicles that run loaded on unpaved haul roads, where wheel-end reduction gives climbing torque and protects the drivetrain from shock. The family starts at 18 t wide-body trucks and scales up to 70 t-class haulers.

Customization

Available on request: ratio selection within each published range, spring centre variants, brake configurations for continuous downhill duty, and documentation for target-market certification. Minimum order quantities apply for special builds.
