Optimal Loader/Truck Pass Matching

Hydraulic Excavator: 390 - Passes 4
Hydraulic Excavator: 374 - Passes 5
Wheel Loader: 982 - Passes 4
Wheel Loader: 980 - Passes 4-5
Wheel Loader: 972 - Passes 4-5
Note An optimum system match gives you a major productivity advantage. Having matched loading and hauling tools results in increased production and lower system costs per unit of volume moved.
