User manual ZENOAH KOMATSU HM400-2 BROCHURE

[. . . ] Economy mode Engine speeds of the maximum output, downshift, and upshift are set to a lower level. It is appropriate for light 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 advancement in technology. To achieve both high levels of productivity and economical performance, Komatsu has developed the main components with a total control system. [. . . ] The large-capacity, continuously cooled, wet-multiple disc brakes also function as a highly responsive retarder which gives the operator greater confidence at higher speeds when travelling downhill. Retarder Absorbing Capacity (continuous descent): 389 kW 533 HP Articulated steering Fully hydraulic articulated steering offers low-effort operating performance and maneuverability. A minimum turning radius of only 8. 7 m 28'7" provides ability to work in tight areas. 8. 70 m 28'7" 4. 17 m 13'8" Komatsu designed interaxle and differential locking systems The full-time six-wheel drive system reduces slippage. A wet multiple-disk interaxle clutch also locks the three axles in unison for greater traction. The interaxle lock and differential locks can be switched on and off while the truck is travelling, thereby boosting productivity. In addition, the differential lock switch, which is a three position switch, can lock up the rear axle differentials only, or all axles for maximum performance in the worst conditions. 4 5 HM400-2 A R T I C U L AT E D D U M P T R U C K Built-in ROPS/FOPS cab ARTICULATED DUMP TRUCK HM400-2 OPERATOR ENVIRONMENT Komatsu has developed a state-of-the-art, wide comfortable cab. The low level of vibration and noise ensure maximum productivity from the operator. Low-noise designed cab Integrated cab and floor provide airtight cab. The low noise and sound insulated muffler /exhaust pipe contribute to reducing sound levels. All these together offer a quiet and comfortable operator environment. Air suspension seat is standard The air suspension, fabric-covered seat which is adjustable to the operator's weight is provided as standard. The air suspension seat dampens vibrations transmitted from the machine and reduces operator fatigue as well as holding the operator securely to assure confident operation. These structures conform to ISO 3471-1994 standard. Hydro-pneumatic suspension for all terrains The hydro-pneumatic suspension assures a comfortable ride even over rough terrain and ensures maximum productivity and operator confidence. Viscous cab mounts Viscous mounts reduce the noise transmitted to the cab and achieve a quiet 76 dB(A) noise level Electric body dump control lever The low effort lever makes dumping easier than ever. Supplementary steering and secondary brakes Supplementary steering and secondary brakes are standard features. Steering: ISO 5010-1992, SAE J1511 Brakes: ISO 3450-1996 Wide, spacious cab with excellent visibility The wide cab provides a comfortable space for the operator and a full size buddy seat. Large electrically operated window and the operator's seat positioned to the left side ensures superior visibility. 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 by operators and greater productivity. The front under view mirrors are increased to two from one, and the rear view mirrors increased to four from two. Newly employed laminated glass in the windshield assures safe operation. In addition, electric heated rear window facilitates defrosting. 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 Komatsu on-board monitoring system makes the machine very friendly and easy to service. Steering wheel and pedals Low effort pedals reduce operator fatigue when working continuously for long periods. The tiltable, telescoping steering column enables operators to maintain the optimum driving position at all times. 6 7 HM400-2 A R T I C U L AT E D D U M P T R U C K ARTICULATED DUMP TRUCK HM400-2 EASY MAINTENANCE The HM400-2 has been designed to keep service time down and productivity up by reduced number of grease points, easy access to filters, and longer intervals between oil changes. Tiltable cab The cab can be tilted rearward 32 degrees to provide easy maintenance/service for the engine and transmission.
