Additional Information
The Komatsu HM300-5 features the innovative Komatsu Traction Control System (KTCS), which automatically monitors and applies independent brakes to slipping wheels, ensuring maximum traction without operator intervention. The advanced hydro-pneumatic suspension on both axles delivers an exceptionally smooth ride over rough haul roads, reducing operator fatigue and structural stress. Additionally, the fuel-efficient SAA6D125E-7 engine incorporates selective catalytic reduction (SCR) and a variable geometry turbocharger to meet stringent emission standards while lowering operating costs on Australian work sites.
