Wheeled excavators experience boost in lift force

|  October 19, 2007 |

The Caterpillar D-Series wheel excavators – M313D, M315D, M316D, M318D and M322D – deliver increased lift capacity and faster cycle times through changes in engines and hydraulics compared to the C-Series machines they replace. The D-Series ranges in size from 127 net horsepower and an operating weight of about 31,000 pounds to 166 net horsepower and an operating weight of about 48,000 pounds. Improvements include ACERT Cat engines, dedicated hydraulic pumps for the excavator swing function and the addition of a heavy lift mode for a 7-percent boost in lifting capacity. Each excavator also has more drawbar pull, enhanced bucket and stick force, greater dig depth and longer reach than the C-Series machines.
