Multi-shank ripper: Hydraulically controlled parallelogram ripper with three shanks. Weight (including hydraulic control unit) . [. . . ] Current features: Effective length of track on ground is consistent. Shoe slippage is minimized; therefore, high traction is obtained. The idler does not oscillate under load, providing excellent machine balance. Blade and ripper penetration force remains stable for increased productivity. Fulcrum of major bogie Outstanding Productivity SIGMADOZER New features on K-Bogie undercarriage system: Fulcrum of minor bogie Engine The Komatsu SAA6D140E-5 engine delivers 335 kW 449 HP at 2000 rpm. The fuel-efficient Komatsu engine, together with the heavy machine weight, make the D275AX-5E0 a superior crawler dozer in both ripping and dozing production. The result is efficient use of engine power, less fuel consumption, and faster cycle times. SIGMADOZER Engine Torque converter Transmission Shape of dozed material Rippers The variable giant ripper features a long sprocket center-to-ripper point distance, making ripping operation easy and effective while maintaining high penetration force. The variable giant ripper is a parallelogram single shank ripper ideal for ripping in tough material. The ripping angle is variable, and the depth is adjustable in three stages by a hydraulically controlled pin puller. The multi-shank ripper is a hydraulically controlled parallelogram ripper with three shanks. Track shoe slip control system (option) Eliminates the need for the operator to constantly control engine power output with the decelerator while ripping. Operator fatigue is substantially reduced. Lockup "OFF" Maneuverability is improved because the operator is free to focus on the ripping application without having to monitor the track shoe slippage. Repair costs are significantly lowered and undercarriage life is prolonged with the reduction in track shoe slippage. Shape of dozed material Lockup "ON" Semi-U blade 6 Track shoe slip control panel The track shoe slip control system will contribute to lower fuel costs, because the engine output is automatically controlled to optimum levels for operation. 7 D275AX-5E0 C R AW L E R D O Z E R CRAWLER DOZER D275AX-5E0 WORKING ENVIRONMENT Operator Comfort Operator comfort is essential for productive work. The D275AX-5E0 provides a quiet, comfortable environment where the operator can concentrate on the work at hand. EASY MAINTENANCE Preventative Maintenance Comfortable ride with new cab damper mounting and K-Bogie undercarriage D275AX-5E0's cab mount uses a new cab damper which provides excellent shock and vibration absorption capacity with its long stroke. Cab damper mounts combined with new K-Bogie undercarriage, softens shocks and vibration while traveling over adverse conditions, that are impossible to absorb with conventional cab mounting methods. The soft spring of cab damper isolates the cab from machine body, suppressing vibration and providing a quiet, comfortable operating environment. Preventative maintenance is the only way to ensure long service life from your equipment. That's why Komatsu designed the D275AX-5E0 with conveniently located maintenance points to make necessary inspections and maintenance quick and easy. Centralized service station To assure convenient maintenance, the transmission and HSS oil filters, power train oil level gauges and hydraulic tank are arranged in the right side of the machine. Modular power train design Power train components are sealed in a modular design that allows the components to be dismounted and mounted without oil spillage. Oil pressure checking ports Pressure checking ports for power train components are centralized to promote quick and simple diagnosis. Rubber Boot All warning and monitor lamps are lit for photo shooting. Maintenance free disc brakes Wet disc brakes require less maintenance. Monitor with self-diagnostic function With the starting switch turned ON, the monitor displays P Enlarged engine room Engine room space is enlarged by increasing engine hood height, facilitating maintenance of the engine and related equipment. Perforated holes on the engine hood are discontinued, preventing dust and rain entering and to keep engine area clean. Hexagonal pressurized cab (optional) The cab's new hexagonal design and large tinted glass windows provide excellent front, side, and rear visibility. Silicon oil Spring on the display, check-before-starting and caution items appear on the lower right part of the panel. If the monitor finds abnormalities, corresponding warning lamp blinks and Cab damper mounting warning buzzer sounds. The monitor displays engine rpm and forward/reverse gear speed on the upper part of the monitor during operation. When abnormalities occur during operation, action code and service meter are displayed alternately. When a critical action code is displayed, the caution lamp blinks and a warning buzzer sounds to prevent the development of serious problems. Air filters and a higher internal air pressure combine to prevent dust from entering the cab. New suspension seat D275AX-5E0 uses a new suspension seat.
