[. . . ] The result: the best gear for any driving situation. Komatsu develops and produces all major components, such as engines, electronics and hydraulic components, in house. With this "Komatsu Technology, " and adding customer feedback, Komatsu is achieving great advancements in technology. To achieve both high levels of productivity and economical performance, Komatsu has developed the main components with a total control system. The result is a new generation of high performance and environment friendly machines. K-ATOMiCS (Komatsu Advanced Transmission with Optimum Modulation Control System) Payload Meter (PLM) (Option) Long wheelbase and wide tread With an extra-long wheelbase, a wide tread and an exceptionally low center of gravity, the HD465-7R hauls the load at higher speed for greater productivity, and delivers superior driving comfort over rough terrain. [. . . ] "Skip-shift" function Optimum travel speed automatically selected in response to angle of ascent. Shift down Skip-shift F4 F1 Reduced frequenShift hold cy of downshift F4 and smoother F4 operation are provided. Conventional Built-in ROPS/FOPS cab These structures conform to ISO3471 ROPS standard, and ISO 3449 FOPS standard. Ergonomically designed cab The ergonomically designed operator's compartment makes it very easy and comfortable for the operator to use all the controls. The result is more confident operation and greater productivity. Viscous cab mounts Viscous mounts reduce the noise transmitted to the cab and achieve a quiet 77 dB(A) noise level. Easy-to-See instrument panel The instrument panel makes it easy to monitor critical machine functions. In addition, a caution light warns the operator of any problems that may occur. This makes the machine user friendly and easy to service. Shift down Shift down Shift down F2 F1 Electric body dump control The low effort lever makes dumping easy. A positioning sensor is installed for dump body control which significantly reduces the shock made by the lowering of the dump body. F3 F2 Ideal driving position settings The 5-way adjustable operator seat and the tilt-telescopic steering column provide an optimum driving posture, for increased driving comfort and more control over machine operation. The suspension seat dampens vibrations transmitted from the machine and reduces operator fatigue as well as holding the operator securely to assure confident operation. 78mm 3" width seat belt is provided as standard equipment. Hydropneumatic suspension for all terrains The hydropneumatic suspension assures a comfortable ride even over rough terrain and ensures maximum productivity and operator confidence. F4 F3 Nitrogen gas Oil F4 Three-mode hydropneumatic suspension (Auto-suspension) (Option) Suspension mode is automatically switched to one of three stages (soft, medium and hard) according to load and operating conditions, for a more comfortable and stable ride. Supplementary steering and secondary brake Supplementary steering and secondary brakes are standard features. Steering: ISO 5010, SAE J1511 Brakes: ISO 3450 6 Machine shown may include optional equipment. 7 HD465-7R O F F - H I G H W AY T R U C K OFF-HIGHWAY TRUCK HD465-7R RELIABILITY FEATURES Komatsu components Komatsu manufactures the engine, torque converter, transmission, hydraulic units, and electrical parts on this dump truck. VHMS controller monitors the health conditions of major components, enables remote analysis of the machine and its operation. This process is supported by the Komatsu distributors, factory and design team. This contributes to reduced repair costs and to maintaining maximum availability. Satellite communication Customer job site KOMATSU Parts colored with yellow show cast-steel components Automatic Spin Regulator (ASR) (Option) ASR automatically prevents the rear tires on either side from slipping on soft ground for optimal traction. Rigorous dump body design The body is built of 130 kg/mm2 184, 900 PSI wearresistant high-tensile steel with a Brinell hardness of 400. The side and bottom plates of the dump section are reinforced with ribs for added strength. Pedal-operated secondary brake If there should be a failure in the foot brake, the parking brake and front disc brakes are activated as a pedal operated secondary brake. In addition, when hydraulic pressure drops below the rated level, the parking brake is automatically actuated. Internet Extended oil change intervals Reliable hydraulic system The oil cooler is installed underneath of the radiator, improving the reliability of the hydraulic system during sudden temperature rises. Further, in addition to the main filter, a 25micron line filter is at the entrance to the transmission control valve. This system helps to prevent secondary faults. In order to minimize operating costs, oil change intervals Lead-free radiator In addition to compliance with emission regulations, a leadfree aluminum core is used for the radiator to meet global environmental requirements. have been extended: Engine oil 500 hours Hydraulic oil 4000 hours Komatsu distributors WebCARE Server Personal computer terminal (for downloading data) Centralized arrangement of filters Brake cooling oil recovery tank To protect the environment, a tank is installed to recover brake cooling oil in the event of brake floating seal leakage. The filters are centralized so that they can be serviced easily. Flat face-to-face O-ring seals Flat face-to-face O-ring seals are used to securely seal all hydraulic hose connections and to prevent oil leakage. Nipple Hose O-ring Protection functions supported by electronic control Item Function Disc wheels (Flange type rims) Disc wheels (Flange type rims) provide easy removal/installation for the tires. 8 Downshift inhibitor Over-run inhibitor Reverse inhibitor Forward/Reverse shift inhibitor Anti-hunting system Neutral safety Even if the driver downshifts accidentally, a speed appropriate to the current gear is automatically set, preventing over-runs. The vehicle is prevented from moving backward when operating the body. This device makes it impossible to shift from forward to reverse when the vehicle's speed surpasses 4 km/hour.
