Komatsu's 30.9 ton capacity HM300 Articulated Truck is powered by a Tier 4 final Komatsu engine. A Komatsu Traction Control System along with two working modes and a standard payload meter (PLM) provide the operator with the tools needed to complete the job efficiently and profitably even in the most severe underfoot conditions. A heated, center located air suspension operator seat, a forward facing training seat, separate rear view monitor, and large LED multi-language monitor ensure the operator is working productively in comfort throughout a full shift.
