Operator Station A technologically advanced cab, featuring joystick controls, provides unmatched comfort and visibility. 4 Steering and Implement Controls Two joysticks offer precise control and unparalleled ease of operation. This advanced technology makes the 120M the most operator-friendly motor grader in the world. 6 Structures, Drawbar, Circle and Moldboard The 120M frame provides a solid working platform, and the DCM delivers service ease and precise blade control for maximum productivity. [. . . ] ACERT Technology enhances overall engine performance while dramatically reducing exhaust emissions. The C6. 6 engine with ACERT Technology uses multiple injection fuel delivery to precisely shape the combustion cycle. Several small ignitions lower combustion chamber temperatures, generates fewer emissions and optimizes fuel combustion. Bottom line: more work output for your fuel cost. Power Management. The 120M Power Management System automatically delivers an additional five horsepower in each forward gear 1st through 4th, and each reverse gear 1st through 3rd. This standard feature optimizes rimpull for all gears by balancing traction, speed and horsepower while conserving fuel. The system limits horsepower in lower gears, which helps reduce wheel slip where traction is limited. With the Variable Horsepower Plus (VHP Plus) option, an additional five-horsepower is delivered in each forward gear 5th through 8th for more power at higher speeds. 12 Hydraulics The 120M electro-hydraulics enable advanced machine controls with precise and predictable movements. Cat ® XTTM Hose. Cat hose technology allows high pressures for maximum power and reduced downtime. Hose clips prevent hose rubbing and excessive vibration for lower owning and operating costs. Hydraulic flow is proportioned to ensure all implements operate simultaneously with little effect on the engine or implement speeds. If demand exceeds pump capacity, all cylinder velocities are reduced by the same ratio. PPPC valves have different flow rates for the head (red) and rod ends (blue) of the cylinder. This ensures consistent extension and retraction speeds for each cylinder, and gives the operator a consistent and predictable response every time an implement control is moved. Advanced Electro-Hydraulic System. This technology is the foundation for revolutionary changes of the machine and implement controls. Advanced joystick controls provide unmatched controllability with precise, predictable hydraulic movements and the reliability you expect from Caterpillar. Blade float is built into the blade lift control valves and is optional for some auxiliary hydraulic functions. The blade float feature allows the blade to move freely under its own weight. By floating both cylinders, the blade can follow the contours of the road when removing snow. Floating only one cylinder permits the toe of the blade to follow a hard surface while the operator controls the slope with the other lift cylinder. Independent Oil Supply. Large, separate hydraulic oil supply prevents crosscontamination and provides proper oil cooling, which reduces heat build-up and extends component life. The time proven load-sensing system and the advanced Proportional Priority Pressure-Compensating (PPPC, or "triple-PC") electro-hydraulic valves on the 120M are designed to provide superior implement control and enhanced machine performance in all applications. [. . . ] Cat dealers help you size the right machine for your operations and can estimate component life, preventative maintenance cost, and the true cost of production. Consider the financing options available, as well as day-to-day operating costs. Look at dealer services that can be included in the cost of the machine to yield lower equipment owning and operating costs over the long run. Diagnostics programs such as Scheduled Oil Sampling, S·O·SSM analysis, Coolant Sampling and Technical Analysis help avoid unscheduled repairs. Grouped Service Points. [. . . ]
