The Cat 730 with a 17.5 m³ (23 yd³)/28 tonnes (31 tons) capacity, offers demonstrated reliability and durability, high performance and productivity and a new world-class cab to improve operator comfort and ease of operation. Updating the successful 730C2 to include the new cab design makes the 730 a more attractive proposition for our customers. Class leading levels of performance and new features such as Advanced Automatic Traction Control (AATC) and Assisted Hoisting Control create operator comfort, making a productive machine all day long while retaining all axle enclosed wet brakes and Advanced Productivity Electronic Control Strategy (APECS).
