OVERVIEW

BENEFITS

FEATURES AT A GLANCE

ACHIEVE GREATER PRODUCTIVITY

Productivity improvement up to 7%.
Up to 3% increase in torque puts more power to the ground.
Various body options, along with liners and sideboard combinations, offer flexibility to move a wide density of material without compromising on payload.
Machine speed limit feature allows the machine to run at an optimal gear for the selected speed.

BOOST FUEL EFFICIENCY

Standard economy mode provides maximum fuel savings with minimal productivity impact.
Haul your truck at a more fuel-efficient engine speed and gear selection with speed limiting.
Engine Idle Shutdown automatically initiates when the truck is in park and idles for a preset amount of time—conserving fuel.
Built with the same reliable Cat® 3412E air-to-air aftercooled engine, featuring Hydraulic Electronic Unit Injector (HEUI™) forcefficient operation.
Deliver reliable performance in the most extreme haul-road conditions with the Cat front dry caliper and rear oil-cooled multiple disc brakes.

DESIGNED FOR SAFETY

Ground level access to the machine shutoff switch stops all fuel to the engine when activated, shutting down the machine.
Safe ground level access to daily maintenance points means less servicing time is required.
Overload speed limiter works with truck payload system to reduce machine speed automatically when the truck is overloaded.
Equipped with a retractable four-point seat belt and a shoulder harness to improve operator safety.
Seat belt indicator implements both visual and audible alerts to the operator when seat belt is not fastened.
Secondary steering automatically engages if the power source for the normal steering fails.
Save on fuel costs with Engine Overspeed Protection— electronically senses the engine condition and automatically upshifts one gear to prevent engine overspeed.

EASY TO OPERATE

Completely redesigned cab interior for a whole new standard in visibility, comfort, and productivity.
Enjoy a more automotive-like, all-in-one integrated parking brake.
Intuitive, ergonomic controls and multifunction display keep operators focused on their work.
Designed for precise steering, Cat integrated steering and suspension system provides excellent maneuverability, minimal tire wear, and superior ride control.

INTEGRATED CAT TECHNOLOGIES

Second gear reweigh improves accuracy of the haul as it recalculates the payload.
Instrumentation and Advisor system provide a three-category warning system and quick access to stored diagnostic data.
Product Link™ system connects to each machine wirelessly, allowing you to monitor location, hours, fuel use, productivity, idle time, and diagnostic codes.
Vital Information Management System (VIMS™ ) – User-friendly interface monitor is available in the cabin to monitor key parameters of the machine.
Truck Production Management System (TPMS) provides accurate weighing of the materials, stores 2,400 payload cycles, and reports on weights, haul cycle times, and distances with date and time stamps (optional attachment).

INCREASED PERFORMANCE AND RELIABILITY

Build operator confidence with Automatic Retarder Control (ARC), providing excellent control while reducing operator effort for a smoother ride.
Enjoy better productivity with a more responsive Traction Control System, improves control in poor underfoot conditions.
Standard wet disc braking on rear wheels offers extra protection and enhanced safety.
Prevent any slippage with an integrated park brake for slope holding capability.

LOWER MAINTENANCE COSTS

Safe, convenient maintenance with a machine platform and groundlevel battery disconnect.
The Advisor system provides quick, onboard diagnostic data and lowers operating costs.
Rugged cylinders use a large diameter bore and a low-pressure nitrogen/oil design for long life with minimal maintenance.
Traction Control System (TCS) engages sooner in the slip, extending tire life and cycle times.
