Cat 120M2/120M2 AWD

Angled cab doors, a tapered engine enclosure and patented sloped rear window assure excellent visibility to the work area.

Caterpillar has built the most comfortable cab in the industry, replacing the control levers and steering wheel with two joystick controls, and lengthening the cab for more leg room. Machine design features, like angled doors, provide excellent visibility.

Multiple isolation mounts along with relocated hydraulic pump and valves significantly improve operator comfort and productivity.

Two electro-hydraulic joysticks require up to 78% less hand and wrist movement than conventional lever controls for greatly enhanced operator comfort and efficiency. The intuitive control pattern allows both new and experienced operators to quickly become productive.

Provides easy, precise and consistent throttle operation. An automatic/manual mode switch offers flexibility for different applications and operator preferences.

Automatically returns the machine to a straight frame position from any angle with the touch of a button.

Cat Advanced Control Joysticks allow the operator to easily control automated grading solutions, Cat GRADE with Cross Slope, AccuGrade™, and Snow Wing. Both new and experienced operators can also configure auxiliary hydraulic functions (such as ripper, front plow blade, etc.) without taking their hands off the controls decreasing fatigue, increasing productivity.

To meet Tier 4 Interim/Stage IIIB equivalent emission standards and beyond, Cat aftertreatment components have been designed to match application needs. System components include a Diesel Oxidation Catalyst (DOC), which uses a chemical process to convert regulated emissions in the exhaust system, and a Diesel Particulate Filter (DPF) that traps particulate matter that is carried into the exhaust stream.

A C7.1 ACERT engine and Cat Clean Emissions Module deliver the performance and efficiency that customers demand, while meeting Tier 4 Interim/Stage IIIB equivalent emission standards.

Hydraulically actuated, oil bathed, multi-disc service brakes at each tandem wheel (1) offer the industry's largest total brake surface area (2) for dependable stopping power and long brake life. The brake wear indicator/compensator system (3) maintains brake performance and indicates brake wear without disassembly, for fast servicing and longer brake service life. The spring-applied, hydraulically released multi-disc parking brake, sealed and oil-cooled for long life and low service, is integrated into the Operator Presence System to prevent unintended machine movement.

The frame, drawbar and one-piece forged steel circle are designed for durability in heavy duty applications. The strong A-frame drawbar uses a durable tubular design. The front 240° of circle teeth are hardened to reduce wear and ensure component reliability.

A large tapered roller bearing at the lower pivot carries loads evenly and smoothly. Sealed to prevent contamination, a locking pin prevents articulation for safety during service or transport.

Heat-treated rails, hardened cutting edges and end bits, and heavy duty bolts assure reliability and long service life. The link bar allows extreme moldboard positioning for bank sloping, ditch cutting and cleaning.

Grade technologies combine digital design data and in-cab guidance to help you reach target grade quickly and accurately, with minimal staking and checking. That means you'll be more productive, complete jobs faster, in fewer passes, using less fuel, at a lower cost.

Cat GRADE with Cross Slope is an integrated 2D system that provides automated control to one side of the blade to help operators more easily achieve accurate surface cross slope. The system calculates blade slope positioning and adjusts the left or right cylinder to achieve target slope, reducing operator inputs by up to 50%. The operator can select which side of the blade to control automatically and swap direction on the return pass without readjusting the settings. Elevation is controlled manually by matching grade or automatically by adding an elevation control device, such as a sonic or laser. The operator can monitor cross slope in real-time on the in-cab display and make quick adjustments using integrated joystick buttons while keeping hands on the controls.

The proven load-sensing system and the advanced Proportional Priority Pressure-Compensating (PPPC or “triple P – C”) electro-hydraulic valves provide superior implement control and enhanced machine performance in all applications. 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 (red) and rod ends (blue) of the cylinder, ensuring consistent extension and retraction speeds.
• Balanced Flow – Hydraulic flow is proportioned so all implements operate simultaneously with little effect on the engine or implement speeds.

A front mounted push plate/counterweight or front lift group are available. The front lift group can be combined with a front dozer blade or front scarifier for added versatility.

Made to penetrate tough material fast and rip thoroughly for easier movement with the moldboard. The ripper includes three shanks (with holders for five). Nine scarifier shanks can also be added for additional versatility.

Features are designed to enhance operator and job site safety, such as drop-down rear lights and a rearview camera. Among many standard safety features are laminated glass, back-up lights, and perforated tandem walkways and grab rails.

The parking brake remains engaged and hydraulic implements disabled until the operator is initially seated and the machine is ready for operation.

Brakes are located at each tandem wheel to eliminate braking loads on the power train. Redundant brake systems utilize accumulators to enable stopping in case of machine failure, further increasing operational safety.

This optional feature uses accumulators to help absorb impact loads to the moldboard by allowing vertical blade travel. Blade lift accumulators help reduce unnecessary wear and also help reduce impact loading for enhanced operator safety.

To help reduce objects flying from the tires, as well as build-up of mud, snow and debris, optional fenders can be added.

Stay productive with best-in-class parts availability. Your Cat dealer can even help boost your profits with operator training.

And when it's time for component replacement, your Cat dealer can help you save even more. Genuine Cat Remanufactured parts carry the same warranty and reliability as new products at savings of 40 to 70 percent for power train and hydraulic components.
