Komatsu
HD405-8
The 44.1 ton capacity HD405-8 Mechanical Truck features the same technology that puts large Komatsu haul trucks ahead of the pack. Seven-speed, fully automatic K-Atomics transmission with lock-up, a hydro-pneumatic suspension system and oil cooled multi-disc brake retarder give the HD405-8 the outstanding performance expected from a Komatsu product. Komatsu Traction Control (KTCS) is standard for optimum traction in all ground conditions. The tire size has been increased from 18.00 R33 to 21.00 R33 for improved wear performance.
