HD325-8

The Komatsu HD325-8 Mechanical Truck is a 40.3 ton capacity workhorse. Very maneuverable, the MacPherson-strut-type front suspension gives the HD325-8 the tightest turning radius in its class. With two working modes the operator can most effectively take advantage of the fully automatic seven-speed transmission with lock-up feature. A hydropneumatic suspension gives the operator a comfortable ride while maintaining more material in the bed for more production. Komatsu Traction Control (KTCS) is standard for optimum traction in all ground conditions.

Features

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: 23'7" 7.2 m

Rear wet multiple-disc brakes ensure highly reliable and stable brake performance. The large-capacity, continuously oil cooled, multiple-disc brakes also function as a highly responsive retarder, which gives the operator greater confidence at higher downhill speeds.

Retarder Absorbing Capacity: 924 HP 689 kW

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.

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.

The ergonomically designed operator's compartment provides the operator a convenient control layout and comfortable environment for more confident operation and greater productivity.

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.

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.

Inclined stairs with handrails provide easy access to the cab and service deck.

Cast-steel components are used in critical areas of the main frame where loads and shocks are most concentrated.

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.

The battery compartment is located at ground level to facilitate daily checks and battery replacement.
