User manual ZENOAH KOMATSU HD405-7 BROCHURE

[. . . ] 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 greater 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. Long wheelbase and wide tread With an extra-long wheelbase, a wide tread and an exceptionally low center of gravity, the HD405-7 hauls the load at higher speed for more production, and delivers superior driving comfort over rough terrain. K-ATOMiCS (Komatsu Advanced Transmission with Optimum Modulation Control System) In Cab Laptop In Office Memory card reader Automatic Retard Speed Control (ARSC)(Option) ARSC allows the operator to simply set the downhill travel speed and go down slopes at a constant speed. [. . . ] Brakes require no adjustments for wear, meaning even lower maintenance. 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. Centralized greasing points (Option) Greasing points are centralized at three locations. Pedal-operated secondary brake If there should be a failure in the foot brake, the parking brake and front disc brakes are activated as pedal operated secondary brake. In addition, when hydraulic pressure drops below the rated level, the parking brake is automatically actuated. Extended oil change intervals In order to minimize operating costs, oil change intervals have been extended: Engine oil 500 hours Hydraulic oil 4000 hours 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 adopted for the radiator to comply with global environmental requirements. Centralized arrangement of filters The filters are centralized so that they can be serviced easily. Brake cooling oil recovery tank To protect 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 Downshift inhibitor Over-run inhibitor Reverse inhibitor Forward/Reverse shift inhibitor Anti-hunting system Neutral safety Function Even if the driver downshifts accidentally, a speed appropriate to the current gear is automatically set, preventing over-runs. When descending grades, if the vehicle's speed surpasses the maximum for the current gear, the rear brakes automatically operate, 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. 8 9 HD405-7 O F F - H I G H WAY T R U C K DIMENSIONS OFF-HIGHWAY TRUCK HD405-7 SPECIFICATIONS ENGINE Model.
