Productivity, safety, comfort
Operator Environment The D8R features an isolation-mounted, pressurized cab that reduces noise and vibration. Large, single pane windows offer good views all around the machine for maximum productivity and enhanced job site safety. The Comfort Series seat is offset by 15 degrees for better visibility. It features fully adjustable positioning and armrests to provide a comfortable platform when working on steep grades or slopes. Gauges and warning lights on the in-dash instrument cluster are easy to read, even in direct sunlight. The Cat Electronic Monitoring System (EMS) provides alert indicators that monitor key machine components. The system provides three levels of warning and system monitoring so the operator can stay informed and still concentrate on the job. Heating and air conditioning vents evenly distribute airflow within the cab. The cab is pre-wired for a 12-volt or 24-volt radio, equipped with two speakers, an antenna and a radio mount recessed in the headliner.
Dozer and Ripper Controls All D8R controls are ergonomically designed for low-effort and ease of operation. The dozer and ripper control levers feature load-sensing hydraulics for added operator comfort and precise control. Load-sensing hydraulics adjusts implement and hydraulic power to increase both operator and machine efficiency. The hydraulic system features a dedicated implement pump to ensure adequate hydraulic power is available. The D8R features optional dual blade tilt for further productivity enhancement.
Comfortable, Non-tiring Operation Low effort controls and a Cat Contour Series Seat, with wide retractable seat belt, provides an environment that reduces fatigue and maximizes productivity.
Steering and Transmission Control The operator uses a single handle control to perform all direction and gear selection. The tiller bar control allows the operator to work more precisely in close areas around structures, grade stakes and other machines. Differential Steering provides the finest modulation in the industry in maintaining power to both sides of the track during a turn and maintaining constant center-line speed. Hydraulics via a separate dedicated pump, are used to steer and has a dedicated pump to deliver more load-moving power during turns.
Clear Full-circle View A tapered hood and notched fuel tank give the operator a clear line of site to front and rear work areas.
