[. . . ] The speed can be set at increments of 1 km/h 0. 6 MPH per click (±5 km/h 3. 1 MPH of setting speed adjustment) to match the optimum speed for the slope. Also, since the retarder cooling oil temperature is always monitored, the speed is automatically lowered. Mode selection system with VHPC The system allows selection of the appropriate mode between two modes <Power mode > or <Economy mode> according to each working condition. The mode is easily selected with a switch in the operator's cab. When the key switch is turned on, Economy mode is selected automatically. [. . . ] Komatsu dump trucks are manufactured with an integrated production system under strict quality control system guidelines. EASY MAINTENANCE Advanced monitoring system The Komatsu advanced monitoring system identifies maintenance items, reduces diagnostic times, indicates oil and filter replacement hours and displays abnormality codes. This monitor system helps to maximize machine production time. Reliable hydraulic system A large capacity oil cooler is installed in each hydraulic circuit, improving the reliability of the hydraulic units during sudden temperature rises. Further, in addition to the main filter, 10 = 3 (min) line filter is located at the entrance to the transmission control valve. This system helps prevent secondary faults. Electric circuit breaker A circuit breaker is adopted in important electric circuits that should be restored in a short time when a problem occurs in the electrical system. High-rigidity frame Front support is integrated with the frame. The frame rigidity is increased drastically. As a result, flexural rigidity and torsional rigidity that are indicators of drivability and riding quality are significantly improved. 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. Hose Nipple Centralized greasing points Greasing points are centralized at three locations, it enables to approach from ground level. O-ring Sealed DT connectors Rugged and durable dump body design The standard dump body is made of high-tensile-strength steel with a Brinell hardness of 400 for excellent rigidity and reduced maintenance cost. The V-shape and Vbottom design also increase structural strength. The side and bottom plates of the dump section are reinforced with ribs for added strength. Main harnesses and controller connectors are equipped with sealed DT connectors providing high reliability, water resistance and dust resistance. Wet multiple-disc brakes and fully hydraulic controlled braking systems realize lower maintenance costs and higher reliability. Wet disc brakes are fully sealed to keep contaminants out, reducing wear and maintenance. Brakes require no adjustments for wear, meaning even lower maintenance. The parking brake is also an adjustment-free, wet multiple-disc system for high reliability and long life. Added reliability is designed into the braking system by the use of three independent hydraulic circuits providing hydraulic backup should one of the circuits fail. Fully hydraulic braking systems eliminate the air system so air bleeding is not required, and water condensation that can lead to contamination, corrosion and freezing is eliminated. Vehicle Health Monitoring System (VHMS) 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. Satellite communication (Option) Customer job site KOMATSU Internet Protection functions supported by electronic control Item Function Extended oil change intervals In order to minimize operating costs, oil change intervals have been extended: Engine oil 500 hours Hydraulic oil 4000 hours Komatsu distributors WebCARE Server Personal computer terminal (for downloading data) 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. When running near a shift point, smooth automatic shifting takes place. The engine is prevented from starting when the shift lever is not in neutral. When descending grades, if the vehicle's speed surpasses the maximum for the current gear, the rear brakes automatically operate, preventing over-runs. Centralized arrangement of filters The filters are centralized so that they can be serviced easily. Payload Meter (PLM) (Option) PLM allows the production volume and the working conditions on the dump truck to be analyzed and controlled directly via a personal computer. And also the loadage is indicated with the outside lamp. The system can store up to 2900 working cycles. ECOLOGY Lead-free radiator In addition to compliance with emission regulations, a lead-free aluminum core is used for the radiator to meet global environmental requirements. Disc wheels (Flange type rims) Disc wheels (Flange type rims) provide easy removal/installation for the tires. 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. 10 11 OFF-HIGHWAY TRUCK DIMENSIONS HD785-7 3500mm 11'6" 10 33'2 0mm " 10 505mm 450mm 5050mm 16'7" 4695mm 15'5" 1860mm 6'1" 1'6" 27 4325mm 14'2" . 00 R49 4950mm 16'3" 27 . 00 R49 2150mm 7'1" 3190mm 10'6" 10290mm 33'9" TRAVEL PERFORMANCE To determine travel performance: Read from gross weight down to the percent of total resistance.
