Komatsu HD605-8 MECHANICAL TRUCKS
Product Feature
Small Turning Radius
The McPherson strut type front suspension has a special A-arm between each wheel and the main frame. The wider space created between the front wheels and the main frame increases the turning angle of the wheels. The larger turning angle correlates to a smaller turning radius.
Fully Hydraulic Controlled Wet Multiple-Disc Brakes and Retarder
Wet multiple-disc brakes ensure highly reliable and stable brake performance. The large-capacity, continuously-oilcooled, multiple-disc brakes also function as a highly responsive retarder, which gives the operator greater confidence at higher downhill speeds.
Komatsu Advanced Transmission with Optimum. Modulation Control System (K-ATOMiCS) with Skip Shift Function
Fully automatic control selects the optimum gear, according to vehicle speed and the engine speed. The shift point automatically changes, depending on the acceleration of the vehicle. This avoids unnecessary fuel consumption.
Komatsu Traction Control System (KTCS)
New KTCS ensures optimum traction in soft or wet road conditions. The system monitors for wheel slippage at the rear axle, and an acceleration sensor allows determination of a high speed turn versus slippage.
Ergonomically Designed Cab
The ergonomically designed operator's compartment provides the operator a convenient control layout and comfortable environment for more confident operation and greater productivity.
Air Suspension Seat
The heated and ventilated, air suspension, fabric-covered seat is adjustable to the operator’s weight, and is provided as standard. The air suspension seat dampens vibrations transmitted from the machine to reduce operator fatigue. A three-point operator seat belt is standard.
Rearview Monitor System
The operator can view behind the vehicle on the full color monitor, located on the right side of the dashboard. This monitor can be always ON, or only when the shift lever is in the reverse position. Visual distance guidelines can be added for the operator's convenience.
Convenient Access
Inclined stairs with handrails provide easy access to the cab and service deck.
High Rigidity Frame
Cast-steel components are used in critical areas of the main frame where loads and shocks are most concentrated.
Integrated Payload Meter
PLM is a tool to manage the hauling cycle payloads and to analyze the production volume and working conditions of the dump truck for specific time periods. Loaded weight is shown on the payload display (on the LCD unit), and by the external display lamps in real time, while loading.
Ground Accessible Battery Compartment
The battery compartment is located at ground level to facilitate daily checks and battery replacement.
