Komatsu unveils HD465-8, HD605-8 off-highway trucks with more power, redesigned cab

Updated Dec 2, 2016

Komatsu has updated its HD465 and HD605 off-highway trucks with several improvements aimed at improving the trucks’ production.

First, the HD465-8 and HD605-8 are now powered by a Komatsu SAA6D170E-7 engine that increases power to 724 horsepower over the Dash-7 models. The engine employs a diesel particulate filter and performs DPF regeneration passively with no action required from the operator and no interruption in operation.

Thanks to the new engine, fuel consumption on the new 465 is reduced by up to 7 percent and reduced by up to 12 percent on the 605. Further reducing fuel consumption is an auto idle shutdown feature which shuts the machine down after a preset idle time.

Komatsu now includes its Traction Control System as a standard feature on these trucks. The system automatically applies independent brake assemblies to achieve optimum traction in varying ground conditions, without compromising steering performance, Komatsu says. The trucks also feature Komatsu’s Advanced Transmission with Optimum Modulation Control System (K-ATOMICS) which adjusts shifting performance based on demand in order to deliver a more comfortable ride while reducing material spillage.

The improved cab on these trucks features a new air-suspension, high-back, ventilated and heated seat along with a 7-inch color display and a separate rearview monitor. Operators have access to both an integrated payload meter and automatic retard speed control which maintains a selected downhill travel speed appropriate for the grade.
