Comfort, productivity, advanced technology.
Angled cab doors, a tapered engine enclosure and patented sloped rear window assure excellent visibility to the work area.
Maximum Control, Maximum Comfort
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.
The Cat® Comfort Series suspension seat and arm/wrist rests are fully adjustable for improved comfort and productivity. Extra leg room, easy-to-reach long-life rocker switches and revolutionary joystick controls make this the most comfortable cab in the industry.
Standard HVAC system
The high capacity system dehumidifies and pressurizes the cab, circulates fresh air, seals out dust and keeps windows clear.
Low Interior Sound and Vibration Levels
Multiple isolation mounts along with relocated hydraulic pump and valves significantly improve operator comfort and productivity.
In-Dash Instrument Cluster
Easy-to-read, high-visibility gauges and warning lamps keep the operator aware of critical system information.
Unprecedented precision and ease of operation.
Ease of Operation
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. Electronically adjustable control pods help position joysticks for optimal comfort, visibility and proper operation.
- The left joystick primarily controls the machine direction and speed including steering, articulation, return-to-center, wheel lean, gear selection, left moldboard lift cylinder and float.
- The right joystick primarily controls drawbar, circle and moldboard functions including right moldboard lift cylinder and float, moldboard slide and tip, circle turn, drawbar center shift, electronic throttle control and manual differential lock/unlock.
Intuitive Steering Control
Joystick lean angle mirrors the steer tires’ turning angle. A brake tensioning system holds the joystick in position until the operator moves it. The steering control automatically reduces steering sensitivity at higher ground speeds for comfortable and predictable control.
Electronic Throttle Control
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.
Auxiliary Pod and Ripper Control (Optional)
Ergonomically positioned to allow simple, comfortable operation for the multiple hydraulic options.
- Four fingertip controls and a mini joystick maximize control of up to six hydraulic circuits. Individual functions can be programmed with Electronic Technician (Cat ET). The auxiliary hydraulic pod is provided when the machine is configured with three or more auxiliary functions.
- Infinitely variable roller switches provide precise control of the rear ripper and/or front lift group (when equipped).
Reliable, integrated solutions.
Cat NOx Reduction System
The Cat NOx Reduction System captures and cools a small quantity of exhaust gas, then routes it into the combustion chamber where it drives down combustion temperatures and reduces NOx emissions.
To meet Tier 4 Interim/Stage IIIB 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. The DOC, DPF and Cat Regeneration System are contained in a Caterpillar designed Clean Emission Module (CEM) that protects the components, minimizes the aftertreatment footprint and simplifies maintenance.
Cat Regeneration System
The Cat Regeneration System is designed to work transparently, without any interaction needed from the operator. Under most operating conditions, engine exhaust is hot enough to oxidize soot through passive regeneration. If supplemental regeneration is needed, the Cat Regeneration System elevates exhaust gas temperatures to burn off soot in the Diesel Particulate Filter (DPF). This is a process that happens automatically, but the operator can initiate the cycle when convenient or interrupt regeneration as needed. A soot level monitor can be viewed on the Cat Messenger screen and regeneration indicator lights are integrated into the front console.
Power and reliability.
A Cat C9.3 ACERT™ engine and Cat Clean Emissions Module deliver the performance and efficiency that customers demand, while meeting Tier 4 Interim/Stage IIIB emission standards. The C9.3 ACERT engine has superior torque and lugging capability to pull through sudden, short-term loads and maintain consistent, desirable grading speeds to get work done faster without downshifting. The High Pressure Common Rail Fuel System improves precision and control with full electronic injection that boosts performance and reduces soot.
Hydraulic Demand Fan
The hydraulic demand fan automatically adjusts cooling fan speed according to engine cooling requirements. This reduces demand on the engine, putting more horsepower to the ground and improves fuel efficiency. Swing-out design allows easy access to cooling cores and reduces clean out time.
Maximum power to the ground.
Automatic Differential Lock
Unlocks the differential during a turn, re-locks when straight, for easier operation and lower power train protection.
The Cat sealed spindle keeps bearings free from contaminants and lubricated in a light weight oil. The Cat “Live Spindle” design places the larger tapered roller bearing outboard where the load is greater, extending bearing life.
Allows precise control of machine movements and excellent modulation, critical in close-quarter work or finish grading.
Smooth Shifting Transmission
Several key innovations ensure smooth, powerful shifts.
- Full Electronic Clutch Pressure Control (ECPC) system optimizes inching modulation for smooth shifts and directional changes, reducing stress on gears.
- Controlled Throttle Shifting helps to smooth directional and gear changes without using the inching pedal.
- Load Compensation ensures consistent shift quality regardless of blade or machine load.
- This standard feature automatically shifts the transmission at optimal points so the operator can focus on the work to help improve safety, productivity and ease of operation.
- Power Shift Countershaft Transmission and the Cat C9.3 engine maximize power to the ground. Eight forward/six reverse gears optimize productivity.
- Engine Over-Speed Protection prevents downshifting until an acceptable safe travel speed has been established.
Bolt-On Modular Rear Axle
Improves serviceability and contamination control with easy access to differential components.
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.
Service ease and precise blade control.
Heavy Duty Durability
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.
Aggressive Blade Angle
Allows material to roll more freely along the blade, particularly dry materials or cohesive soils. Better material control gets the job done faster, requires less power and saves fuel.
Fast, Easy Adjustment Means Tight Components
Shims and patented top-adjust wear strips are easy to add or replace, dramatically reducing downtime and operating costs. Durable nylon composite wear inserts maximize circle torque and component life. Sacrificial brass wear strips between the blade mounting group and moldboard can be replaced easily. Shimless Moldboard Retention System uses vertical and horizontal adjusting screws to keep moldboard wear strips aligned for reduced blade chatter, precise blade control and dramatic reductions in service time.
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.
Sharing key data among systems helps optimize machine performance and aids serviceability.
- Cat Messenger, combined with full systems integration, enhances diagnostic capability. Machine system errors are displayed in both text and fault codes for quick analysis of critical data.
- Electronic Technician (Cat ET) lets service technicians access stored diagnostic data and configure machine parameters through the Cat Data Link.
- Low Battery Elevated Idle raises idle speed when low system voltage is detected, ensuring adequate system voltage and improving battery reliability.
- Automatic Engine Deration protects the engine and aftertreatment by automatically lowering engine torque output and alerting the operator if critical conditions are detected.
Advanced machine control.
Advanced Electro-Hydraulic System
Incorporates a state-of-the-art electro-hydraulic system as the foundation for revolutionary changes in machine and advanced joystick controls.
Allows the blade to move freely under its own weight. By floating both cylinders, the blade can follow the contours of the road, especially useful when removing snow. 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.
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.
Load Sensing Hydraulics (PPPC)
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.
Solutions to make work easier and more efficient.
Cat Grade Control Cross Slope
Cross Slope is a factory installed machine control and guidance system that allows for accurate and real-time positioning of the moldboard without off-machine infrastructure. Harnesses, sensors and the in-cab display are fully integrated into the machine so the system is ready to work from the factory. The system helps the operator more easily achieve the desired cross slope by automating one end of the blade. The system also helps save time and materials so that even less experienced operators can achieve better results, more quickly. The system is designed for easy scalability, supporting all two- and three-dimensional upgrades to be fully compatible with all AccuGrade™ kits.
AccuGrade Ready Option
Optional factory-installed brackets and hardware make the grader ready for dealer installation of the AccuGrade grade control system. Installation is simplified, and integration of the components provides greater protection to enhance system reliability.
AccuGrade is a dealer-installed blade control system which enables operators to cut and fill to grade with increased accuracy, minimizing the need for traditional survey stakes and grade checkers. AccuGrade includes Cross Slope, Sonic, Laser, Global Navigation Satellite System (GNSS) and/or Universal Total Station (UTS) technologies to automatically control the blade. In-cab displays show precise elevation and real-time cut/fill information. More accurate blade positioning helps operators get to grade faster, with fewer passes than ever before. The AccuGrade System significantly improves grading productivity and accuracy by as much as 50 percent over conventional methods.
