Power and reliability

BENEFITS AND FEATURES

The Cat C18 engine with ACERT Technology gives you the performance you need to maintain consistent grading speeds for maximum productivity. Superior torque and lugging capability provide the power to pull through sudden, short-term increases in loads. ACERT Technology lowers combustion chamber temperatures and optimizes fuel combustion to generate more work output for your fuel cost. ACERT engines also generate fewer emissions to meet the needs of operations around the world. With engine speed limited to 1950 rpm, cylinder velocities are lowered to help you reduce fuel consumption by up to 5%.* The altitude rating is increased, and the rest of the power train has been updated to maintain the same ground speed and power. *Actual fuel savings may vary based on specific site operations and emission level.

Hydraulic Demand Fan The hydraulic demand fan automatically adjusts the cooling fan speed according to engine cooling requirements. When cooling demand is reduced, you benefit from more power to the ground and improved fuel efficiency.

Compression Brake The standard three-phase compression brake enables higher travel speeds downhill, while reducing wear on brake components. This improves overall productivity and lowers your maintenance costs.

Ether Starting Aid A standard ether starting aid feature helps cold-weather startups in extreme temperatures.

• Balanced Planetary Transmission provides superior load distribution and heat dissipation for longer transmission life.
• Engine Over-Speed Protection prevents downshifting until an acceptable safe travel speed has been established.
• Stall speed protection limits engine speed at high stall ratios to help protect the driveline and machine systems.

Front and Rear Axles The sealed spindle keeps front axle bearings lubricated and protected from contaminants. The Cat “Live Spindle” design places the larger tapered roller bearing on the outside, where the load is greater, extending bearing life. A bolt-on modular rear axle improves serviceability and contamination control with easy access to differential components.

Hydraulic Brakes Oil-bathed multi-disc service brakes are hydraulically actuated for smooth, predictable braking and lower operating costs. Brakes are located at each tandem wheel for a large total brake surface area to give you dependable stopping power and longer life.

Service ease and precise blade control

BENEFITS AND FEATURES

Caterpillar designs motor grader frame and drawbar components to give you performance and durability in heavy duty applications. The one-piece forged steel circle stands up to high stress loads, and a sacrificial wear system helps keep your service time and costs down. The articulation hitch features a large tapered roller bearing to carry loads evenly and smoothly. It is sealed to prevent contamination and a locking pin prevents articulation for safety during service or transport.

Blade Angle and Moldboard An aggressive blade angle helps you work more efficiently by allowing material to roll more freely along the blade. The moldboard features heat-treated rails, hardened cutting edges and end bits, and heavy duty bolts to give you greater reliability and long service life. Optimized moldboard curvature and large throat clearance help you move material more efficiently.

Easy Maintenance for More Uptime A series of shims, strips and wear inserts are easy to add or replace. This keeps drawbar-circle moldboard components factory-tight for higher quality work, and saves you service time and costs. An adjustable rear circle drive reduces service time and loading to help increase system life. Six bolt-on tooth segments on the circle can be individually replaced to reduce cost and downtime for maintenance.

Advanced machine control

BENEFITS AND FEATURES

State-of-the-art electro-hydraulics give you advanced machine controls with precise and predictable movements.

Load Sensing Hydraulics (PPPC) A proven load-sensing system and advanced Proportional Priority Pressure-Compensating (PPPC) electro-hydraulic valves give you superior implement control and enhanced machine performance. Continuously matching hydraulic flow/pressure to power demands creates less heat and reduces power consumption.

• Consistent, Predictable Movement - PPPC valves have different flow rates for the head and rod ends of the cylinder, so you can count on consistent, predictable implement response.
• Balanced Flow - Hydraulic flow is proportioned to give you confidence that all implements will operate simultaneously without slowing the engine or speed of some implements.

Blade Float Allows the blade to move freely under its own weight. By floating both cylinders, the blade can follow the contours of the haul road. 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. An optional Variable Down Pressure feature allows you to select the amount of down force when the blade is in float. This helps you extend cutting edge life and is effective for removing snow and mud from a road surface.

Independent Oil Supply Large, separate hydraulic oil supplies prevent cross-contamination and provide proper oil cooling, which reduces heat build-up and extends component life. Cat XT™ hose allows high pressures for maximum power and reduced downtime.
