[. . . ] Plus, there is generous clearance between the heel of the blade and main frame, even with the toe sharply angled down. CLSS with Proportional Flow Hydraulic System Power on Demand Normally, the variable displacement pump idles at low output. When it senses a load requirement, the pump supplies quick flow and pressure to match the demand. The result is less hydraulic system heat, quick response and lower fuel consumption. The bottom line is greater efficiency. Extra-long lift cylinders let the moldboard reach 835 mm 2'9" below grade. Blade Angle A long wheel base allows the operator to obtain an aggressive moldboard angle. [. . . ] This wear system helps keep components tight for fine grading and allows easy replacement. Komatsu also uses replaceable metal wear items in the following areas: · Circle and moldboard tip bracket bearings · Moldboard slide rail Electronic Overspeed Protection helps prevent engine and transmission damage from premature downshifting and grade-induced overspeeding. Low Operating Effort Implement controls are designed to reduce operator fatique. Properly spaced control levers and short lever throws allow the operator to use multiple controls with one hand. Electronic Transmission Control produces smooth shifting, which enables the operator to maintain a uniform grading surface if shifting is required. Smooth shifts also extend the life of the transmission by placing less stress on transmission clutches. A single lever controls direction, speed and parking brake. Balanced Flow When the operator uses several controls at one time, flow is proportional to ensure several implements can operate simultaneously. Cylinder Socket Dust Seals Constant Implement Speed Implement speed is constant regardless of engine speed because of the large pump output and proportional flow control function. · Blade Lift and Drawbar Sideshift Cylinder sockets have dust seals to prevent dust from entering inside the sockets causing wear. Low Effort Inching Pedal gives the operator, when in direct drive mode, precise control of machine movement. This is especially important for operators who are not familiar with operating a torque converter drive motor grader. Optional Protection Systems · Blade Lift Accumulators absorb shocks when the moldboard contacts immovable objects. It provides precise control while allowing relief from vertical impact loads. · Circle Drive Slip Clutch protects the drawbar, circle and moldboard from horizontal shocks when an object is hit near the toe or heel of the blade. This option is most useful in applications where hidden objects are frequently encountered. 4 5 GD555-3 WORKING WORKING ENVIRONMENT ENVIRONMENT Excellent Visibility Exceptional visibility helps improve operator confidence and productivity in all grader applications. Well positioned blade linkage provide an unobstructed view of the moldboard and front tires. Tapered engine hood provide good visibility to the rear of the machine, especially to the rear ripper. MOTOR GRADER Excellent Serviceability · Large hinged engine service doors · Maintenance free all hydraulic disc brakes · Message center · Self-diagnostic system Quiet Cab (Optional) With the doors closed, the quiet environment keeps the operator alert and focused. The cab includes built-in storage space for personal items such as a lunch box, coffee cup, and a hook for a coat. Low Effort Pedals, hydraulic controls, and transmission shifter reduce operator strain and fatigue. Pedals are angled and raised off the cab floor to make them easy to reach. Easy-to-Read Gauges Electronic monitoring system checks important machine systems and provides the operator with three levels of warning. Adjustable Control Console The control console is adjustable backward and forward to facilitate entry and exit from the cab. There are handrails on both sides of the cab so the operator need not grasp the steering wheel when entering the cab. Optional Air Conditioner Well-positioned air conditioning vents keep the operator comfortable through a wide range of outside conditions. In warm weather, the operator can get cold air flow towards his/her back even when the front lower window is opened. 6 7 MAINTENANCE MAINTENANCE FEATURES FEATURES Superior Serviceability Easy Access to Service Areas · Large hinged doors are standard and provide easy access to the engine and radiator service points. · · Lubrication points for articulation joint are remote-mounted. · · Tandem oil check point is conveniently located at the end of the tandem. Service meter is located on the left side of the steering console, offering a clear view from the ground.
