Easy-to-Load Body Heaped capacity 14. 7 m3 19. 2 yd3 Low loading height 2670 mm 8'9" High strength body constructed of thick wearresistant steel having 400 Brinell hardness See page 5. High Performance and Environment-friendly SAA6D125E-5 ecot3 Engine Gross horsepower 232 kW 311 HP North American EPA Tier 3 and EU Stage 3A emission certified Engine power mode selection system realizes both greater productivity and improved fuel economy Higher engine output and torque improve productivity See page 4. 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. [. . . ] Rugged enough for the toughest jobs, the HM250's frame is designed using a rigid box structure with connecting torque tubes made of high strength low alloy steel. Komatsu's new "ecot3" engines are designed to deliver optimum performance under the toughest of conditions, while meeting the latest environmental regulations. "ecot3" - ecology and economy combined with Komatsu technology to create a high performance engine without sacrificing power or productivity. 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. High Performance SAA6D125E-5 Komatsu Engine The Komatsu engine delivers faster acceleration and higher travel speeds with high horsepower per ton. Advanced technology, such as Common Rail Injection system (CRI), air-to-air aftercooler, and an efficient turbo-charger enables the engine to be North American EPA Tier 3 and EU stage 3A emission certified. High torque at low speed, impressive acceleration, and low fuel consumption ensures maximum productivity. 7. 96 m 26'1" 4. 01 m 13'2" 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 full advantage of high output power. It is appropriate for job sites where the truck meets high resistance. Economy mode Engine speeds for the maximum horsepower output and the downshift and upshift speeds are set to a lower level. This mode is selected for maximum economy and lighter work applications. 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. 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 HM250. 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): 296 kW 397 HP 4 5 HM250-2 A R T I C U L AT E D D U M P T R U C K Easy-to-See Instrument Panel ARTICULATED DUMP TRUCK HM250-2 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. Electric Body Dump Control Lever The low effort lever makes dumping easy. A positioning sensor is installed for dump body control witch significantly reduces the shock made by the lowering of the dump body. 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. 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. Wide, Spacious Cab with Excellent Visibility The wide cab provides a comfortable space for the operator and a full size buddy seat.
