System Match Efficiency

Efficient loading/hauling system starts with a perfect match.

Efficient Combination

For full truck payloads with minimum loading time, an efficient loading/hauling system starts with a perfect match. Cat wheel loaders are matched with Cat articulated and off-highway trucks to maximize volume of material moved at the lowest operating cost per ton.

The 986K equipped with the standard linkage is a perfect four pass match for the 770G (38.6 tonnes/42.6 tons). The 986K equipped with a high lift linkage is capable of loading a 772G (47.7 tonnes/52 tons) in 5 passes and a 773E or 773G (56 tonnes/61.7 tons) in 6 passes.
