New Articulated Dump Truck is Tier 4 Final Certified
Komatsu America’s new HM300 articulated dump truck, powered by a 325-hp
(242-kW) Komatsu SAA6D125E-7 engine
that is EPA Tier 4 Final emissions certified,
carries a 30.9-ton (28-mt) payload and
has a gross vehicle weight of 117,881 lb
(53,470 kg). The engine uses an advanced
electronic control system to manage the
air-flow rate, fuel injection, combustion
parameters, and aftertreatment functions
to optimize performance, reduce emissions, and provide advanced diagnostic
capability. This control system is also integrated into the machine’s onboard diagnostics systems and KOMTRAX, Komatsu’s
standard telematics system.
Body design optimization gives the unit
increased body capacity and payload. Its 9-ft 2-in. (2,820-mm) loading height matches with 30-ton to 60-ton hydraulic excavators or 5-yd
3to 7.5-yd
3
wheel loaders. Two
single-staged body lift cylinders provide a
70° dump angle. The HM300 features the
Komatsu Traction Control System (K-TCS)
and K-ATOMiCS—Komatsu Advanced
Transmission with Optimum Modulation
Control System.
The ROPS/FOPS Level 2 certified cab
features a new designed rounded front
dash panel with easy to reach switches. A
high resolution 7-in. LCD monitor offers
enhanced capabilities and displays information in 25 languages for global support.
Through the monitor, the operator can
modify settings for items such as Auto Idle
Shutdown, check operational records, or
see when the next maintenance event is
due. The HM300 also provides easier service access, increased cooling capacity, and
two standard hydraulically driven autoreversing fans to help keep the radiator and
charge air cooler clean. It is equipped with
the exclusive Komatsu EMMS (Equipment
Management Monitoring System), which
has enhanced diagnostic features that give
the operator and technicians greater monitoring and troubleshooting capabilities.
