CAT® C7 ENGINE
Provides optimum power and fuel efficiency, combined with Power Management and Electronic Throttle Control, that assure maximum productivity. The 120K2 is certified to Bharat Stage III emissions standards.
The 120K2 offers enhanced horsepower in the lower gears (1-3), which provides improved performance for tough applications like ripping and heavy blading, as well as the ability to carry more material for improved productivity.
The Power Shift transmission features direct drive and electronic control for smooth, powerful shifts at any speed. Provides on-the-go, full-power shifting and inching capability. Direct drive delivers superior fuel efficiency and better “feel” of blade loads, material hardness and ground speed.
The oil disc brakes located at each tandem wheel eliminate power train braking loads and reduce service time. The large brake surface area provides dependable braking capability and extended life before rebuild.
Front axle with Cat sealed spindle keeps the bearings free from contaminants and lubricated in a lightweight oil to reduce owning and operating costs.
Balanced Hydraulic flow and implement control valves ensure all implements operate simultaneously. Proportional hydraulic flow provides outstanding ‘feel’ and predictable movement. Independent oil supply prevents cross-contamination and provides proper oil cooling, signifying less heat build-up and extended component life.
A load sensing variable displacement pump and advanced hydraulic valves provide superior implement control and better machine performance. Continuously matching hydraulic flow and pressure to power demands creates less heat and reduces power consumption.
120 K Series 2 cabs are designed to keep operators comfortable and productive. Features like low effort pedals and controls, adjustable implement controls and adjustable steering wheel angle make work easier for the operator. A clear view to the moldboard heel and tandem tires enhance productivity and safe operation.
The instrument panel, with easy-to read, high-visibility gauges and warning lamps, places vital machine information and diagnostic capability in easy view of the operator. The dash includes an engine coolant temperature gauge, an articulation gauge, voltage gauge and fuel level gauge. Service brake air pressure gauges are also standard. All major systems are monitored by warning lights.
Some additional cab features include storage area, adjustable control console and coat hook. Optional offerings include power port, air conditioner/heater, suspension seat, defroster fan, sun shade, backup lights, Product Link™ ready, and AccuGrade™ System ready. [NOTE: Some attachments are region specific].
Frame structure – provides consistency and strength. Drawbar, circle and moldboard are designed for high strength and optimum durability for any application. Blade lift accumulator is an optional feature and helps absorb impact loads and reduce unnecessary wear and as well as avoids unintended machine movement resulting in increased operator safety.
WORK TOOLS AND ATTACHMENTS
Allows expansion of machine versatility, utilization, and performance. The list includes:
- Moldboard options
- Ground engaging tools
- Rear ripper/scarifier
- Front mounted groups
- Mid-mount scarifier
- Snow removal work tools
AccuGrade uses positioning and guidance technologies, machine sensors, and automatic blade control to help operators get to grade faster, easier and more efficiently. Digital design plans, real-time cut/fill data, and in-cab guidance give operators detailed information to work more confidently and achieve greater accuracy, in fewer passes, using less material. Operators can stay on grade and improve productivity and accuracy by nearly 50 percent over conventional methods. Grade stakes and checkers are minimized, making the work site safe, efficient, and cost effective. AccuGrade technologies include Cross Slope, Sonic, Laser, GPS, and/or Universal Total Station (UTS).
ACCUGRADE ATTACHMENT READY OPTION (ARO)
K Series 2 machines can be equipped with the AccuGrade ARO. The attachment option includes built-in mounting points and internal wiring, making installation of the AccuGrade grade control system faster and easier.
CAT PRODUCT LINKTM
Product Link helps take the guesswork out of equipment management with remote monitoring capabilities for your machine or your entire fleet. Track asset location, hours, fuel usage, diagnostic codes, idle time and more through the web based secure VisionLink user interface.
Grouped service points on the left side of the machine ensure proper maintenance. Easy access to service areas speeds up maintenance and ensures that routine service is performed on time. Extended service intervals reduce downtime, operating cost.
