Most Powerful Track Loader On the Market

摘要

Having introduced the 953D and 963D track-type loaders two years ago, Caterpillar is now following suit with the D-Series introduction of the largest crawler loader in the market, the 973. At 148 and 189 net horsepower, respectively, up by more than 15 and 25 percent, respectively, over predecessor models, the Caterpillar 953D and 963D (shown here) are powered by the Cat C6.6 ACERT engine. An electronically controlled hydrostatic drive system provides independent power and control of each track, offering fast acceleration, infinitely variable speeds, and automatic, on-the-go, direction changes.
