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.
Wheel Loaders: 972M/972M XE - Passes 3–4
