New CAT Equipment

730 Articulated Truck

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).

Optimal Loader/Truck Pass Matching

Wheel Loaders: 966M/966M XE - Passes 4
Wheel Loader: 962M - Passes 4–5
Wheel Loader: 950M - Passes 5
Hydraulic Excavators: 336F/336F XE - Passes 5–6
Hydraulic Excavators: 349F/349F XE - Passes 4–5
Note An optimum system match gives you a major productivity advantage. The 730 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.
