Overview

MOBILE. AGILE. VERSATILE.

Cat® wheel dozers combine the power of a track dozer with the mobility of a wheeled machine to help deliver high production at low operating costs in a variety of applications — from surface mining cleanup to coal stock piling, road maintenance to reclamation.

Benefits

IMPROVED MAINTENANCE

Make regular maintenance more convenient with accessible controls located inside the cab.

ADDITIONAL SAFETY

Grouped ground level engine and machine controls allow for safe and easy daily maintenance.

ENHANCED OPERATOR COMFORT

Comfortable cab and low effort controls with reduced vibration levels help operators work more productively throughout the day.

Features At A Glance

Solid through-width push beams transfer and absorb stresses through a larger portion of the frame.
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.
Delayed engine shutdown allows your machine to cool before shutting down the engine to help prevent engine and after-treatment damage.
Resilient, durable blades are designed with excellent dozing and rolling characteristics.

The Cat C15 engine is designed for maximum fuel efficiency in the most demanding conditions.
Load sensing hydraulic steering system helps enable precise machine control for easier loading.
Experience increased efficiency with variable displacement piston pumps.
World-class Cat planetary powershift transmission features Single Clutch Speed Shifting (SCSS) for smooth, consistent shifting and efficiency. Enable autoshift mode to automatically upshift or downshift based on machine speed, optimizing performance and conserving fuel.
Equipped with Cat torque converter (TC) with lock-up clutch which helps optimize fuel efficiency by eliminating TC losses while transferring more power to the ground.

Standard rear vision camera to help enhance operator visibility and improve workspace safety.
Battery disconnect, emergency engine shutdown, and stairway light switch are accessed through the ground level power service center.
Cab-mounted LED beacon helps provide warning for others near the machine.

Integrated technologies help 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 lower operating costs.
Vital Information Management System (VIMS™) touchscreen display helps give access to a wide range of sensor information and enhanced machine data to help resolve problems before machine failure.
Optional Cat Detect technologies help enhance awareness of the environment around the machine for increased safety.

Steering and Transmission Integrated Control (STIC™) system combines directional selection, gear selection, and steering into a single lever, helping to maximize
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 seat-mounted implement and steering controls.
Large backlit membrane switches feature LED activation indicators and ISO symbols for quick function identification.
Reduced interior sound levels help keep operators comfortable throughout their entire shift.

Automatic engine and electrical system shutdown helps conserve fuel and helps reduce component wear when machine is not in use.
Generate less waste with maintenance-free batteries.
Maximize machine life and help 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.

Swing-out fuel, hydraulic oil coolers, and condenser help allow for easy access cleanout.
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.
Optional tire pressure monitoring system provides real-time information to the operator in the cab for optimized tire life.
Electronics bay is conveniently located inside the cab.
Sight gauges offer quick visual inspection to help minimize fluid contamination.
Lighting inside the engine compartment helps improve visibility to service points.
Ecology drains help prevent spills and allow for easier service.
