The Cat® 311F RR reduced radius excavator operates where others don't fit. Offering power, excellent fuel efficiency and low owning/operating costs, the 311F RR is a great option for a wide range of excavator needs.
When rotated 90 degrees and working over the side, only 505 mm (1'8") hangs over the side – ideal when you are working up against a wall, on a narrow road, or other space-restricted area.
Lower your fuel bill without impacting your productivity.
Reduce owning and operating costs with quick, easy-to-do maintenance.
