[. . . ] Japan HM300-1 HM300-1 Articulated Dump Truck ARTICULATED DUMP TRUCK GROSS HORSEPOWER 250 kW 335 HP @ 2000 rpm NET HORSEPOWER 242 kW 324 HP @ 2000 rpm MAXIMUM GVW 49, 875 kg 109, 960 lb WALK-AROUND WALK-AROUND The HM300-1 offers all around maximum productivity with faster travel speed and many features that enhance efficiency, while reducing maintenance costs. From construction sites to landfill - the HM300-1 excels. Komatsu designed, electronically controlled transmission for a comfortable ride. F6-R2 counter-shaft type transmission with K-ATOMiCS (Komatsu Advanced Transmission with Optimum Control System). Wide, spacious cab The wide cab offers a comfortable operator environment Viscous mounts support the cab while absorbing vibrations and noise Interior noise level 76 dB(A) Tiltable cab can be tilted rearward to provide easy service. Easy-to-Load Body Heaped capacity 16. 6 m3 21. 7 yd3 Low loading height 2790 mm 9'2" Robust body constructed of thick wearresistant steel having 400 Brinell hardness Hydro-pneumatic Suspension for all terrains. The hydro-pneumatic suspension in both front and rear suspensions assures a comfortable ride even over rough terrain. Maintenance-free oscillating hitch with tapered roller bearings means lower operating costs by eliminating the need to lubricate the hitch. High performance and environment-friendly SAA6D125E-3 engine Gross horsepower 250 kW 335 HP Fully hydraulic articulated steering Light and easy operation Minimum turning radius 7. 96 m 26'1" Differential locks for excellent traction in rough terrain. The oilcooled multiple-disc interaxle lock can be turned on and off during travel. [. . . ] 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 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): 349 kW 468 HP 449 kW 602 HP (with optional exhaust retarder) 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 the freedom to move about in confined areas. 7. 96 m 26'1" 4 5 HM300-1 OPERATOR OPERATOR ENVIRONMENT 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. ARTICULATED DUMP TRUCK Built-in ROPS/FOPS These structures conform to ISO 3471 and SAE J1040-1988C standards. Air Suspension Seat 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. 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. Electric Body Dump Control Lever The low effort lever makes dumping easier than ever. Viscous Cab Mounts Viscous mounts reduce the noise transmitted to the cab and Supplementary Steering and Secondary Brakes Supplementary steering and secondary brakes are standard features. Steering: ISO 5010-1992, SAE J1511 Brakes: ISO 3450-1996, SAE J1473 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 windows and the operator's seat positioned to the left side ensures superior visibility. achieve a quiet 76 dB(A) noise level 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. 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. Problems are recorded in the monitor and indicated as service codes. This 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 HM300-1 EASY EASY MAINTENANCE MAINTENANCE The HM300-1 has been designed to keep service time down and productivity up by having a maintenance-free oscillating hitch, a reduced number of grease points, easy access to filters, and longer intervals between oil changes. Tiltable Cab The cab can be tilted rearward to provide easy maintenance/service for the engine and transmission. Note: An external hydraulic pump is required to tilt the cab or a service crane can be used after removing only eight bolts. . . SPECIFICATIONS SPECIFICATIONS ENGINE Model .
