Overview

The Cat 730 EJ with a 16.9 m³ (22.1 yd³)/27.1 tonnes (30 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 EJ to include the new cab design makes the 730 EJ a more attractive proposition for our customers. Class leading levels of performance and new features such as Advanced Automatic Traction Control (AATC) and Assisted Ejecting Control create operator comfort, making a productive machine all day long. The machines retain all axle enclosed wet brakes and Advanced Productivity Electronic Control Strategy (APECS).
