[. . . ] The result: the best gear for any driving situation. Payload Meter II (PLM II ) (Option) PLM II allows the production volume and the working conditions on the dump truck to be analyzed and controlled directly via a personal computer. The system can store up to 2900 working cycles. 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 greate advancements in technology. To achieve both high levels of productivity and economical performance, Komatsu has developed the main components with a total control system. [. . . ] 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. 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 standard dump body is made of 160 kg/mm2 227, 520 PSI high-tensile-strength steel for excellent rigidity and reduced maintenance cost. The V-shape design also increases structural strength. The side and bottom plates of the dump section are reinforced with ribs for added strength. Centralized greasing points (Option) Greasing points are centralized at three locations, it enables to approach from ground level. 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. Extended oil change intervals Reliable hydraulic system The oil cooler is installed in the radiator lower tank, 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. Lead-free radiator In addition to compliance with emission regulations, a leadfree aluminum core is used for the radiator to meet with global environmental requirements. In order to minimize operating costs, oil change intervals have been extended: Engine oil 500 hours Hydraulic oil 4000 hours Centralized arrangement of filters The filters are centralized so that they can be serviced easily. 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. 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 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. 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. 9 When descending grades, if the vehicle's speed surpasses the maximum for the current gear, the rear brakes automatically operate, preventing over-runs.
