From Your WPI Team
The Next Generation of Articulated Hauling Is Here.
As your authorized Komatsu dealer serving Texas, Louisiana, and Southern Arkansas since 1924, we’re proud to introduce the all-new Komatsu HM460-6. This isn’t an incremental update — every system was rethought from the ground up.
New high-strength frame. New DBA127 engine. New 9-speed automatic transmission. New KTCS traction system. New four-pillar cab. The result is the most capable, efficient, and operator-friendly articulated haul truck ever offered in North America.
We deliver uptime.™
Performance
More Power. Less Fuel. More Payload.
The new DBA127 engine delivers 518 HP and 2,067 lb·ft of torque — paired with a new 9-speed automatic transmission for up to 22% better fuel efficiency per ton hauled. A new high-strength steel frame and redesigned body add payload without adding weight.

Traction
No Terrain Too Tough.
The Komatsu Traction Control System (KTCS) and cross-axle differential lock deliver six-wheel-drive performance on the most challenging terrain — without sacrificing turning ability or maneuverability.
- KTCS maintains traction without losing maneuverability
- Cross-axle differential lock for maximum off-road capability
- Rollover prevention system monitors machine orientation
- Hydro-pneumatic suspension on all axles for smooth ride
- New high-strength steel frame for structural rigidity
KTCS — six-wheel-drive performance on any terrain
Operator Cab
The Cab That Works as Hard as You Do.
A completely redesigned four-pillar cab with panoramic visibility, a deluxe air-suspension seat with heating and cooling, and dual 8" + 10" monitors. Operator fatigue costs you productivity — the HM460-6 was built to eliminate it.
