User manual ZENOAH KOMATSU HM300-2R BROCHURE

[. . . ] From rough terrain construction sites to landfills - the HM300-2R has the competitive edge. Komatsu designed, electronically controlled transmission for a comfortable ride. F6-R2 counter-shaft type transmission with K-ATOMiCS (Komatsu Advanced Transmission with Optimum Modulation Control System). Transmission shift hold button optimizes the operator control Tiltable cab can be tilted rearward Building on the technology and expertise Komatsu has accumulated since its establishment in 1921, GALEO presents customers worldwide with a strong, distinctive image of technological innovation and exceptional value. The GALEO brand will be employed for Komatsu's full lineup of advanced construction and mining equipment. Designed with high productivity, safety and environmental considerations in mind, the machines in this line reflect Komatsu's commitment to contributing to the creation of a better world. [. . . ] The entire vehicle's suspension delivers a comfortable ride and maximizes productivity. Large Capacity Body and Box Section Frame Structure The HM300 has the large heaped capacity of 16. 6 m3 21. 7yd3 body. The low loading height of 2790 mm 9'2" enables easy loading. The body is built of high strength wear-resistant steel with a Brinell hardness of 400, and the body shape provides excellent load stability. Rugged enough for the toughest jobs, the HM300's frame is designed using a rigid box structure with connecting torque tubes made of high strength low alloy steel. High Performance Komatsu SAA6D125E-5 Engine Powerful turbocharged and air-to-air aftercooled Komatsu SAA6D125E-5 engine provides 254 kW 340 HP. This engine realizes high power in low fuel consumption with Common Rail Injection system (CRI), and thus it delivers higher travel speeds with high horsepower. Also high torque at low speed, impressive acceleration, and low fuel consumption ensure maximum productivity. Komatsu Designed Electronically Controlled Countershaft Transmission The Komatsu designed Electronically Controlled Transmission called K-ATOMiCS has been a success in Komatsu's rigid dump trucks. The electronic clutch modulation system ensures proper clutch pressure when the clutch is engaged. The total control system controls both the engine and transmission by monitoring the vehicle conditions. This high technology system assures smooth shifts without shock and maximizes power train life. Hydraulically Controlled Wet Multiple-Disc Brakes and Retarder Wet multiple-disc brakes with proven performance in larger articulated and rigid trucks are tailored for use in the HM300. 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 Articulated Steering Fully hydraulic articulated steering offers low-effort operating performance and maneuverability. A minimum turning radius of only 7. 96 m 26'1" provides ability to work in tight areas. 7. 96 m 26'1" 4. 01 m 13'2" Komatsu Designed 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 can be switched on and off while the truck is travelling, thereby boosting productivity. In addition, limited slip differentials prevent the tires on either side from slipping on soft ground. travelling downhill. Retarder Absorbing Capacity (continuous descent): 370 kW 496 HP 4 5 HM300-2R 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 HM300-2R 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 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.
