[. . . ] It enables an ideal change in clutch modulation pressure and torque cut-off timing in response to travel conditions. This system and newly added "skip-shift" function ensure smooth shifting and responsive acceleration. Hydropneumatic suspension All four wheels have hydropneumatic suspension with a fixed throttle damper control valve that greatly reduces pitching, rolling and bouncing over rough terrain. Nitrogen gas Oil "Skip-shift" function Optimum travel speed automatically selected in response to Shift down angle of ascent. Skip-shift F4 F1 Reduced frequency of Shift hold F4 shift downs and F4 smoother operation are provided. Current Shift down Shift down Shift down Ideal driving position settings The 5-way adjustable operator seat and the tilt-telescopic steering column create an optimum driving posture, for increased driving comfort and more control over the machine's operations. See everything in quiet comfort Wide windows in the front, side and back, plus plenty of space in the richly upholstered interior, give you a quiet, comfortable environment from which to see and control every aspect of your work. F2 F1 F3 F2 F4 F4 F3 EXCELLENT RELIABILITY AND DURABILITY Sturdy, refined frame Cast-steel components are employed in the main frame in critical areas where loads and shocks are most concentrated. Cast steel Reliable hydraulic system The oil cooler is installed below the retarder, improving the reliability of the hydraulic system during sudden temperature rises. Further, in addition to the main filter, a 52-micron line filter is set at the entrance to the transmission control valve. [. . . ] This allows you to simply set the downhill travel speed and go down slopes at a constant speed (travel speed permitted from brake performance). As a result, you can concentrate on steering. The speed can be set at increments of 1km/h 0. 6mph per one click (±5km/h 3. 1mph of setting speed) to match the optimum speed for the slope. Also, when it is predicted that the retarder oil temperature becomes overheat, since the retarder oil temperature is always monitored, operator is informed this by warning lamp.

PLMII (lC card type payload meter) This system allows the production volume and the working conditions on the dump truck to be analyzed and managed directly via a personal computer. It can store up to 2900 working cycles. Engine exhaust retarder The retarder capacity is increased by 30%, so faster speed is permitted on the downward slope. This improves safety and hauling performance. Three-mode hydropneumatic suspension (optional) In Cab Lap-Top personal computer In Office Personal computer Memory card reader To further enhance driving comfort, automatic three-mode suspension is optionally available. This enables the operator to select one of three cushioning effects (SOFT, NORMAL or HARD), depending on road conditions, for improved damping control. ABS (Anti-lock brake System) RS232C Memory card PLM II Daily report The memory card, card reader and software for data processing are optionally available. ABS is introduced to construction machinery first in the industry by Komatsu's outstanding electronics technology. This system prevents the tire lock under slippery condition while applying service brake and gives safety drive of the truck. ROPS This protects the operator and cab should the truck turn over.
