CAT Cat®12K Motor grader

Performance

Cat C7 ACERT The engine conforms to the United States EPA Tier 3/European Union Stage IIIA Equivalent emission standards or Tier 2/Stage II Equivalent emission standards，Depending on the particular country/Emission standards for the region。

Engine with Powershift Countershaft Transmission，It can transmit power to the ground to the maximum extent.。

Efficiency

Electronic throttle control helps increase productivity by optimizing power and torque，To meet the power requirements of the application。

Large blade angle、Optimized moldboard curvature and wide throat clearance allow material to roll more freely along the blade，So that that efficiency is improve。

The demand-operated hydraulic fan automatically adjusts its speed according to the cooling demand，So as to maximize the power transmission to the ground and improve fuel efficiency。

The engine idle shutdown function is provided to shut down the engine after a set period of times，Thereby saving fuel and helping reduce emissions.。

And is easy to operate

Proportional distribution、Preference、Pressure compensation（PPPC，Proportional Priority Pressure-Compensating）Provides superior control for load sensing hydraulic system、Enhanced performance and greater efficiency。

By automatically shifting the transmission to the optimum gear，Optional auto-shift transmission improves ease of operation and maximizes productivity。

Rocker arms and control switches are within reach。

Proven conventional controls provide industry-standard control modes and feel，Helps achieve precise cutting edge motion。

Serviceability

Rugged nylon composite wear inserts maximize circle torque and extend component life。

Copper moldboard rail wear strips are located between the blade mounting assembly and the moldboard，Easily adjustable and replaceable。

The left service area is close to the ground，Speeds up maintenance and ensures timely routine repair。

Reliability

Leverage rigorous component design and machine validation proces，Unparalleled reliability achieved、Durability and uptime。

At all Caterpillar In the factory，Components are designed and manufactured in accordance with Caterpillar Quality standards。

Comfortable

Optional HVAC、Defroster fan and sun visor for added comfort，And well-placed power ports keep additional communication devices charged and ready at all times。

Technology

Optional Cat AccuGrade™ Use of positioning and guidance technology、Machine Sensors and Automatic Blade Control Function，Helps to be faster、Easier、Achieve the desired grade more efficiently。

Optional Cat Product Link™ With remote monitoring function，Helps you manage your device。

AccuGrade Accessories are available as an option（ARO，AccuGrade Attachment Ready Option）Can be ordered as a factory- or dealer-installed option，Make AccuGrade Faster installation of grade control system、Easier。

Safe

Brakes are mounted on each wheel of the tandem，Largest total brake area in the industry，So that brake force is very reliable。

The standard circle drive slip clutch is used when the blade encounters a hard-to-move object，Protect the drawbar、The circle and moldboard are protected from impact loads.。

The ground level engine shutdown switch allows anyone nearby to shut down the engine in an emergency。

Built-in lock check valve

The operator has a clear view of the moldboard heel and the tandem tire，Increased productivity and operational safety。

The blade lift accumulators absorb the impact loads experienced by the moldboard by allowing the blade to move vertically。
