[. . . ] In addition, the limited slip differentials prevent the tires on either side from slipping on soft ground for maximum traction. See page 4. High Capacity, Reliable, Continuously Cooled, Wet Type Multiple-disc Brakes and Retarder Fully hydraulic controlled wet multiple-disc brake Retarder absorbing capacity (continuous descent) 296 kW 397 HP See page 5. 3 (Optional) KOMTRAX equipped machines can send location, SMR and operation maps to a secure website utilizing wireless technology Machines also relay error codes, cautions maintenance items, fuel levels and much more. 2 HM250-2 A R T I C U L AT E D D U M P T R U C K ARTICULATED DUMP TRUCK Hydro-Pneumatic Trailing Arm Suspension Hydro-pneumatic suspension with proven performance in larger articulated and rigid trucks is tailored for use in the ARTICULATED DUMP TRUCK HM250-1 HM250-2 PRODUCTIVITY FEATURES The combination of high horse power, high travel speeds and an efficient engine with low emissions delivers maximum productivity at cost. Komatsu Technology Komatsu Designed Electronically Controlled Countershaft Transmission The Komatsu designed Electronically Controlled Transmission with 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. [. . . ] 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. Large electrically operated window and the operator's seat positioned to the left side ensures superior visibility. Steering Wheel and Pedals Low effort pedals reduce operator fatigue when working Komatsu's Unique Trailing Arm Suspension Komatsu's unique trailing arm suspension (with hydropneumatic suspension) employed for the front wheels allows the truck to ride smoothly and reduces pitching of the machine to provide excellent ride quality. continuously for long periods. The tiltable, telescoping steering column enables operators to maintain the optimum driving position at all times. 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 three from one, and the rear view mirrors increased to four from two.
