Easy-to-load body Heaped capacity 22. 3 m3 29. 2 yd3 Low loading height 2970 mm 9'9" High strength body constructed of thick wear-resistant steel having 400 Brinell hardness Fully hydraulic articulated steering Light and easy operation Minimum turning radius 8. 7 m 28'7" High performance Komatsu SAA6D140E-5 engine Gross horsepower 338 kW 453 HP Engine power mode selection system realizes both greater productivity and improved fuel economy Higher engine output and torque improve productivity in all applications Photo may include optional equipment. Hydro-pneumatic suspension for all terrains. The hydro-pneumatic suspension in both front and rear suspensions assures a comfortable ride even over rough terrain. Interaxle & differential locks provide excellent traction in rough terrain. The oil-cooled multiple-disc interaxle lock and differential locks can be turned on and off during travel. In addition, the differential locks can lock up all three axles' differentials for maximum traction. High capacity, reliable, continuously cooled, wet type multiple-disc brakes and retarder Fully hydraulic controlled wet multiple-disc brake Retarder absorbing capacity (continuous descent) 389 kW 533 HP 2 3 HM400-2R A R T I C U L AT E D D U M P T R U C K Hydro-pneumatic suspension ARTICULATED DUMP TRUCK ARTICULATED DUMP TRUCK HM400-1 HM400-2R PRODUCTIVITY FEATURES The combination of high travel speeds and an efficient engine delivers maximum productivity at the lowest cost. Komatsu technology Engine power mode selection system The system allows selection of the appropriate mode between two modes <Power mode > or <Economy mode> according to each working condition. Power mode Great productivity can be attained by taking a full advantage of high output power. [. . . ] Rugged enough for the toughest jobs, the HM400's frame is designed using a rigid box structure with connecting torque tubes made of high strength low alloy steel. High performance Komatsu SAA6D140E-5 engine Powerful turbocharged and air-to-air aftercooled Komatsu SAA6D140E-5 engine provides 338 kW 453 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-disk brakes have been proven on Komatsu dump trucks and wheel loaders ensuring highly reliable and stable brake performance. 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 HM400-2R 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 HM400-2R 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. 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.
