OVERVIEW

BENEFITS

FEATURES AT A GLANCE

BUILT TO PERFORM

The full box-section rear frame helps resist torsional shock and twisting forces.
Heavy-duty steering cylinder mounts efficiently transmit steering loads into the frame.
Optimized axle mounting helps result in increased structural integrity.
Achieve long component life with increased size of upper hitch pin, frame plate, and bearing.
Solid through-width push beams transfer and absorb stresses through a larger portion of the frame.
Features fully enclosed hydraulic wet disc brakes for improved performance.
Robust structures withstand the toughest conditions and multiple lifecycles to help improve your bottom line.
In corner dozing, stresses are transferred and absorbed through a larger portion of the frame.

MOVE MORE WITH LESS FUEL

The Cat C18 engine is designed for maximum fuel efficiency in the most demanding applications.
Experience reliable efficiency with complete control over injection timing, duration, and pressure with Mechanically Actuated Electronic Unit Injection (MEUI™).
World-class Cat planetary powershift transmission features consistent, smooth shifting and efficiency through integrated electronic controls.
Extended engine life and improved fuel efficiency with reduced rated speed.
Impeller Clutch Torque Converter (ICTC) and Rimpull Control System (RCS) provide precise rimpull control.
Load sensing hydraulic steering system enables precise machine control for easy loading.
Lock-up torque converter with advanced control of lock-up speed.
On demand cooling fan helps protect investment and lengthens lifecycle.
Fully integrated electronic engine controls provide quick response.

SAFETY FIRST

Optional Cat Detect with Object Detection System (rearview camera and radar) or standard Vision (rearview camera) help increase operator awareness around the machine.
Cab-mounted LED strobes provide warning for others near the machine.
Optional HID or LED lights help provide excellent workspace visibility.
Optional heated mirrors help ensure enhanced visibility for safe operation.

TECHNOLOGY THAT GETS WORK DONE

Integrated technologies allow you to monitor, manage, and enhance your jobsite operations.
Product Link™ remote monitoring helps provide valuable insight into machine or fleet performance through the VisionLink® interface, so you can make decisions that boost jobsite efficiency and low operating costs.
Vital Information Management System (VIMS™) 3G touchscreen monitor gives access to a wide range of sensor information and enhanced machine data to resolve problems before machine failure.
Optional Cat Detect technologies help enhance awareness of the environment around the machine for increased safety.

WORK IN COMFORT

Steering and Transmission Integrated Control System (STIC™) combines directional selection, gear selection, and steering into a single lever, maximizing responsiveness and control, while reducing operator fatigue.
Operators can easily enter and exit the cab with fold-up STIC steer/ armrest, reduced access stairway angles, and standard stairway lighting.
Experience reduced vibrations with isolated cab mounts and seatmounted implement and steering controls.
Reduced interior sound levels help keep operators comfortable throughout their entire shift.

REDUCE ENVIRONMENTAL IMPACT

The engine is available in configurations that meet U.S. EPA Tier 4 Final and EU Stage V emission standards, or noncertified that emits equivalent to U.S. EPA Tier 3.
Automatic Engine Idle Shutdown helps conserve fuel when machine is not in use.
Generate less waste with maintenance-free batteries.
Maximize machine life and lower operating costs with Caterpillar Reman and Certified Rebuild programs, which utilize reused or remanufactured components for 40 to 70% cost savings.
Retrofit packages from Caterpillar deliver new features to older machines to get the most from your investment.

SAVE ON SERVICE AND MAINTENANCE

Machine features ground level or platform access to easily reach daily service points.
Swing-out doors on either side of the engine compartment help provide easy access to critical daily service checks.
Ecology drains help prevent spills and allow for easy service.
Intuitive design includes ground level access to transmission control valves for safe and convenient service.
