Overview
This Productive Grader is Guided by Power and Precision
Equipped with the C7 CAT® engine, a direct drive Powershift transmission, and a load sensing hydraulic circuit, the 140K grader brings power, control, comfort, and productivity to your leveling work.
AdvantagesOptimize Performance
The intermediate shaft Powershift transmission is matched to the engine to optimize ground power.
Increase Efficiency
The dynamic blade orientation, optimal curvature of the shield, and significant clearance between the blade and circle allow materials to roll more freely along the blade.
Easy to Maneuver
The optional Autoshift transmission optimizes productivity by automatically placing the transmission at the optimal speed change points.
Key Features
- Designed to be Performant
- Performance With Less Fuel
- Designed for Drivers
- Reduced Maintenance Time
- Long-Term Profitability and Long Lifespan
- Boosted Productivity by Technologies
- Integrated Security Features
Designed to be Performant
The Cat C7 engine complies with EPA Tier 3 (United States)/Stage IIIA (European Union) emission standards, or equivalent Tier 2/Stage II standards, depending on the country's emission regulations. The Powershift transmission with intermediate shaft is designed to optimize power on the ground.
Performance With Less Fuel
The electronic throttle control improves productivity by combining the power and torque best suited to the application. The dynamic adjustable blades, optimal curvature of the shield, and significant clearance between the blade and circle allow materials to roll more freely along the blade, thereby increasing efficiency. The variable speed hydraulic fan automatically adjusts the speed based on cooling needs, optimizing ground power and improving energy efficiency. The engine idle stop function is available to shut off the engine after a given period of time to save fuel and reduce pollutant emissions.
Designed for Drivers
The Proportional Priority Pressure Compensating (PPPC) provides a load sensing hydraulic circuit with increased control and improved performance and efficiency. The optional Autoshift transmission enhances operation and optimizes productivity by automatically shifting the transmission at optimal speed change points. The toggle and control switches are easily accessible. The proven classic controls offer a control grid that complies with industry standards and sensitivity for precise cutting blade movement.
Reduced Maintenance Time
The long-lasting nylon composite wear inserts optimize the torque of the circle and the component's lifespan. The wear strips of the sacrificial brass sliding rails, located between the blade mounting group and the shield, can be easily adjusted and replaced. Access to the ground-level maintenance area on the left side speeds up maintenance and ensures that periodic maintenance is carried out on time.
Long-Term Profitability and Long Lifespan
The rigorous design of components and the results of machine validation processes result in unprecedented reliability and service life as well as high availability. Components are designed and manufactured in accordance with Caterpillar's quality standards across all Caterpillar sites.
Boosted Productivity by Technologies
The optional AccuGrade™ Cat system uses positioning and guidance technologies, machine sensors, and automatic blade control for faster, simpler, and more efficient leveling operations. The Product Link™ Cat option facilitates equipment management with remote monitoring functions. The AccuGrade Attachment Ready Option (ARO) can be ordered and installed at the factory or by the dealer, speeding up and simplifying the installation of the AccuGrade leveling control system.
Integrated Security Features
The brakes located on each tandem wheel offer the largest braking surface on the market, in order to provide reliable braking power. The standard circle drive safety clutch protects the hitch bar, circle, and shield from impact loads when the blade encounters a stationary object. The ground-level engine stop allows anyone nearby to shut down the machine in case of an emergency. Integrated locking check valves. The clear view of the front end of the shield and tandem tires improves productivity and safety. Blade lift accumulators help reduce impact loads on the shield by allowing vertical movement of the blade.
