Komatsu’s Tier 4 Final engines are built on the solid foundation inaugurated in 1996 with the introduction of Komatsu’s Tier 1 engines.
This new articulated dump truck leverages Komatsu’s leadership in technology and innovation by delivering a more environmentally friendly engine that provides high levels of performance while reducing fuel consumption and operating costs, the company said.
With a 30.9-ton (28 metric ton) payload and a gross vehicle weight (GVW) of 117,892 lb. (53,475 kg), the HM300-5 maintains the productivity and performance of the previous model, and offers improved fuel efficiency to deliver what customers have come to expect from Komatsu articulated dump trucks.
Through body design optimization, the HM300-5 has increased body capacity and payload. The low 9-ft., 2-in. (2820 mm) loading height easily matches with 30- to 60-ton hydraulic excavators or 5 cu. yd. to 7.5 cu. yd. wheel loaders. Additionally, the two single-staged body lift cylinders provide a 70-degee dump angle. Selectable working modes allow the operator to choose between Economy and Power modes to tailor machine performance to the application or work conditions. Komatsu America Corp., www.komatsu.com
