Operator Station The all-new operator station provides maximum comfort and ease of operation.
Operator Comfort. The all-new operator station has been designed to maximize operator comfort and productivity. Pilot operated controls allow for more legroom and a spacious work environment. New Styling. The new ergonomic, automotive styling of the operator station enhances the operator environment. The narrow front dash provides excellent visibility to the front bucket. Integrated storage areas and cupholders are designed for operator convenience. Deluxe ROPS Canopy.
Pilot Operated Joystick Controls Low effort, comfortable controls reduce fatigue and provide more legroom. Joystick Controls. Standard excavatorstyle joysticks provide smooth modulation and are ergonomically designed for low effort control and operator comfort. Without the traditional, rear console, they also provide increased legroom and greater rearward viewing area. Pilot Operated Stabilizer Controls.
Hydraulics Caterpillar sets the standard in power and precision with load-sensing hydraulics. Load-Sensing Hydraulic System. The variable displacement piston pump and flow-sharing hydraulic valves sense work demand and adjust flow and pressure for increased productivity. Load-sensing hydraulics deliver: • Maximum lift and dig forces at any engine RPM • Cooler hydraulic system • Better fuel efficiency • Quieter operation • Reduced wear on components Hydraulic Pump.
Power Train The Cat® C4.4 engine is built for performance, power, reliability and fuel efficiency. Auto-Shift Transmission. The standard automatic transmission matches gears with grade and load conditions. Top gear is selected with the twist grip control on the steering column. At the touch of a switch, manual mode gives the operator control over gear selection, as a power shift transmission. Transmission Kick-Down Switch/ Neutralizer.
Ride Control Standard Caterpillar Ride Control delivers even greater operator comfort. Ride Control System. The Ride Control System incorporates a nitrogen accumulator in the loader lift circuit that smooths the ride in all conditions, including load and carry, highway roading, or simply moving around the job site. Improved Productivity. Ride Control improves material retention in the loader bucket for increased productivity and a cleaner jobsite. Controllability.
