The Caterpillar D7R track-type tractor is said to continue the firm’s R family tradition in providing a simple, robust, easily serviced machine.
The new model incorporates components said by Cat to have a proven history of reliability and durability in the most severe applications, including heavy dozing, ripping, land clearing and mining. The D7R’s Cat C9 ACERT engine, with a net power rating of 174 kW at rated engine speed, meets standards in accordance with China Stage II (GB 20891-2007), EPA Tier 2 and EU Stage II emissions regulations.
Other features on the D7R include a massive mainframe, heavy-duty undercarriage, robust powershift transmission, differential steering, pilot-controlled hydraulics and efficient operator station. The overall design is said by Cat to promote all the elements of proven design for high productivity, long durability and low life time operating costs through ability to rebuild components and overall machine efficiency.
The D7R is said to enable convenient routine maintenance with service points that are readily accessible. To assist in monitoring machine health, sampling ports allow quick collection of fluids for laboratory analysis. With the Cat Electronic Technician, the Cat dealer can quickly diagnose machine performance parameters to reduce downtime and to keep the D7R operating at maximum efficiency.
