Overview

The Cat 730C2, with a 17 m3 (23 yd3) 28 tonnes (31 tons) capacity, offers demonstrated reliability and durability, high performance and productivity, superior operator comfort and lower operating costs. Updating the successful 730C to include all axle enclosed wet brakes makes the 730C2 a more attractive proposition for our customers. Class leading levels of performance and operator comfort make for a productive machine all day long.
