Komatsu has introduced its latest articulated dump truck, a 44-tonner with a redesigned dash control panel as well as a Tier-4 Final engine, that reduces fuel consumption and operating costs.
The HM400-5 is powered y a Komatsu SAA6D140E-7 engine producing 469 hp. The engine uses selective catalyst reduction (SCR) and diesel exhaust fluid (DEF) to reduce emissions. Lower fuel consumption is achieved through an electronic control system which manages airflow, fuel injection combustion parameters and after treatment functions. A variable geometry turbocharger and exhaust gas recirculation (EGR) allow for precise temperature and air management control. The engine is paired with a six-speed automatic transmission.
The truck has a gross weight of 165,633 pounds.
The truck features a low 10-1/2-ft loading height, a dump angle of 70o and Economy and Power modes allowing the operator to customize performance to the application.
