Caterpillar Presents New Cat 311F RR Excavator

Caterpillar has introduced its new Cat® 311F RR excavator, powered with a 70 net horsepower (52 kW) C3.4B engine that meets U.S. EPA Tier 4 Final emissions standards.

The new machine features a reduced radius that limits over-the-side tail swing to just 20 inches (508 mm).

A massive 5,400-pound (2 450 kg) counterweight gives it the stability and working capacity of conventional machines, while design efficiency allows for use of a full-sized cab.

The machine’s compact size is complemented with fuel-saving features and an efficient hydraulic system that powers through tough digging and easily handles a range of work tools.
