[. . . ] You get a machine whose components are designed to work together for higher production, greater reliability, and more versatility. OPERATING WEIGHT 108390 kg 238, 960 lb BLADE CAPACITY Semi-U: 27. 2 m3 35. 6 yd3 Full-U: 34. 4 m3 45. 0 yd3 Extra-low machine profile provides excellent machine balance and low center of gravity. Hydraulic drive radiator cooling fan controlled automatically, reduces fuel consumption and operating noise levels. See page 6. ECMV (Electronic Controlled Modulation Valve) controlled steering clutch/brake system facilitates steering operation. See page 5. Low noise Operator noise: 70dB(A) (Engine at Hi, cooling fan at 70%, and air conditioner OFF. ) Preventative maintenance Centralized service station Enclosed hydraulic piping Modular power train design Oil pressure checking ports See page 9. Dynamic noise (outside): 110dB(A) As per ISO 6395 See page 8. VHMS (Vehicle Health Monitoring System) Simple hull frame and monocoque track frame with pivot shaft for greater reliability. See page 9. Large blade capacities: 27. 2 m3 35. 6 yd3 (Semi-U dozer) and 34. 4 m3 45. 0 yd3 (U dozer) See page 7. The dual tilt dozer (option) increases productivity while reducing operator effort. See page 7. Rippers (option): Variable giant Multi-shank See page 7. Automatic lockup torque converter saves fuel and increases speed and power transmission efficiency on long pushes. [. . . ] The engine is designed to surpass EPA Tier 2 emission regulation, and features direct fuel injection, turbocharger, and air-to-air aftercooler to maximize fuel efficiency. To minimize noise and vibration, the engine is mounted to the main frame with rubber cushions. Large blade Capacities of 27. 2 m3 35. 6 yd3 (Semi-U dozer) and 34. 4 m3 45. 0 yd3 (U dozer) yield outstanding production. High-tensile-strength steel has been incorporated into the front and sides of the blade for increased durability. K-Bogie undercarriage system New K-Bogie Undercarriage System combines prior advantages with new additional features. Current features: K-Bogies that oscillate with two fulcrums assure large amount of track roller vertical travel. Impact load to undercarriage components is minimized and durability of components is improved since track rollers are always in contact with track link. 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. The track shoe slip control system will contribute to lower fuel costs, because the engine output is automatically controlled to optimum levels for operation. Lockup "ON" Track shoe slip control panel 6 7 D475A-5E0 C R A W L E R D O Z E R CRAWLER DOZER D475A-5E0 WORKING ENVIRONMENT Operator Comfort Operator comfort is essential for safe and productive work. The D475A-5E0 provides the operator with a quiet, comfortable environment where the operator can concentrate on the work at hand. EASY MAINTENANCE Preventative Maintenance Preventative maintenance is the only way to ensure long service life from your equipment. That's why Komatsu designed the D475A-5E0 with conveniently located maintenance points to make necessary inspections and maintenance quick and easy. Centralized service station Hexagonal pressurized cab The cab's new hexagonal design and large tinted glass windows provide excellent front, side, and rear visibility. Improved cab sealing, air filters and increased internal air pressure combine to prevent dust from entering the cab. The floor mat and door sill are the same height to facilitate easy cleaning. The high quality cab interior is fully lined with sound absorbing material. To ensure convenient maintenance, the transmission and torque converter oil filters are both arranged next to the power train oil level gauge. VHMS (Vehicle Health Monitoring System) VHMS controller monitors the health conditions of major components and enables remote analysis of the machine and its operation. This process is supported by the Komatsu distributors, factory and design team. This contributes to reduced repair costs and to maintaining maximum availability. Monitor with self-diagnostic function If the monitor finds abnormalities, corresponding warning lamp blinks and warning buzzer sounds. When abnormalities occur during operation, user code and service meter are displayed alternately. When a high importance user code is displayed, a caution lamp blinks and warning buzzer sounds to prevent the development of serious problems. Comfortable ride with new cab damper mounting and K-Bogie undercarriage D475A-5E0's cab mount uses a new cab damper mounting which further improves viscous damper and provides excellent shock and vibration absorption capacity with its long stroke. The cab damper mounting, combined with new K-bogie undercarriage, softens shocks and vibrations while traveling over adverse condition that are impossible to absorb with conventional cab mounting methods. The soft spring cab damper isolates the cab from machine body, suppressing vibrations and providing a quiet, comfortable operating environment. ·Operator noise: 70dB(A) (Engine at high idle, fan speed at 70%, and air conditioner OFF) ·Dynamic noise (outside): 110dB(A) (As per ISO 6395) Satellite communication (option) Customer job site KOMATSU Oil pressure checking ports Pressure checking ports for power train components are centralized to promote quick and simple diagnosis. Internet Gull-wing engine side covers Gull-wing engine side covers facilitate engine maintenance and filter replacement. Side covers are a thick one-piece structure with bolt-on latch to improve durability and repairability. WebCARE server Komatsu distributors Personal computer terminal (for downloading data) Improvement of visibility in rear of blade The shape of the blade heel and the position of the operator's seat are changed so that the operator can check the ground in the rear of the blade during dozing.
