Palm command electronic controlled travel control joystick Palm command travel joystick provides the operator with a relaxed posture and superb fine control. Transmission gear shifting is simplified with thumb push buttons. R RH DOWN SHIFT UP SHIFT LH F Palm command PPC controlled blade/ripper control joystick Blade control joystick uses a PPC (Proportional Pressure Control) valve and blade control joystick ergonomics are similar to the travel control joystick. PPC control combined with the highly reliable Komatsu hydraulic system enables New integrated ROPS cab (Optional) A newly designed cab is integrated with ROPS. High rigidity and superb sealing performance sharply reduce noise and vibration for the operator and helps prevent dust from entering the cab. The result is relaxed operation in a comfortable environment for the operator. In addition, side visibility is increased because external ROPS structure and posts are not required. Outstanding visibility has been achieved. Comfortable ride with cab damper mounting The D155A-6's cab mount uses a cab damper which provides excellent shock and vibration absorption capacity with its long stroke. Cab damper mounts soften shocks and vibration while traveling over adverse conditions, which conventional mounting systems are unable to absorb. The cab damper spring isolates the cab from the machine body, suppressing vibration and providing a quiet, comfortable operating environment. Gearshift pattern preset function When the gearshift pattern is set to either <F1-R2>, <F2R2> or <F2-R3L> in automatic gearshift mode, the gear is automatically shifted, reducing round trip repetition work time and operator's efforts. Automatic gearshift mode UP superb fine control. Large multi-lingual LCD color monitor Fuel control dial Engine revolution is controlled by an electronic signal, providing ease of operation, eliminating maintenance of linkage and joints. Rubber Boot A large user-friendly color monitor enables, accurate and smooth work. Improved screen visibility is achieved by use of TFT liquid crystal display that can easily be read at various angles and lighting conditions. Display data in 10 languages to globally support operators around the world.
