HD465-8

724 net hp drives the 61 ton capacity HD465-8. A very tight turning radius and hydro-pneumatic suspension makes the HD465-8 very maneuverable in close working areas. Cast-steel in high stress areas on the frame gives the truck the durability and reliability mines require. A seven speed fully automatic transmission with lock-up and skip shift give the HD465-8 power and speed to meet demanding production levels. Komatsu Traction Control (KTCS) is standard for optimum traction in all ground conditions.

HD465-8 Walkaround

Features

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.

Minimum Turning Radius: 28'7" 8.7 m

Fully Hydraulic

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.

Retarder Absorbing Capacity: 1,075 HP 802 kW

Komatsu Advanced Transmission

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

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.
If slippage is detected, the brakes are applied independently to each wheel set for optimum traction. This function occurs automatically without operator input and steering performance is not compromised, as with a differential lock system.

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.
