New CAT Equipment

730 EJ Articulated Truck

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).

    Optimal Loader/Truck Pass Matching

    Hydraulic Excavators: 336F/336F XE - Passes 5–6
    Note An optimum system match gives you a major productivity advantage. The 730 EJ is an excellent match for the Cat 349F and 336F Hydraulic Excavators; and Cat 972M, 966M, 962M and 950M Wheel Loaders. Having matched loading and hauling tools results in increased production and lower system costs per unit of volume moved.
    Hydraulic Excavators: 349F/349F XE - Passes 4–5
    Wheel Loaders: 966M/966M XE - Passes 4
    Wheel Loaders: 972M/972M XE - Passes 3–4
