Key features

• Single-reduction design for on-highway duty: fewer moving parts than hub-reduction units, lower weight and straightforward maintenance.
• Wide ratio spread from 2.313 up to 6.167 — tall ratios for fuel-efficient long-haul cruising, short ratios for vocational and loaded startability.
• 11 t and 13 t ratings covering the most common heavy-truck gross weight classes.
• Factory-matched driveline pairing with Weichai engines and FAST transmissions, supplied as one assembled order.
• Produced at HanDe's four Chinese bases on a 1.5 million-axle annual line, with export support in 20+ countries.

Applications

These axles are the standard rear drive units under HanDe-matched heavy commercial vehicles. Operators choose tall ratios on linehaul corridors and shorter ratios for construction-site and vocational cycles where low-speed pulling matters more than cruising economy.

Customization

Available on request: ratio selection within the published range, spring centre variants, air-suspension mounts, ABS readiness, and documentation for target-market certification. Minimum order quantities apply for special builds.
