The two heavy-duty models, which replace the previous generation’s CX470C and CX470C ME, have been renamed to reflect their increased weight. All the new models feature CASE’s fuel-efficient Tier 4 Final (Euro IV) maintenance-free technology with no DPF.
“They offer the high productivity, comfort and safety levels and low running costs that the previously launched D Series models have become known for,” the company said.
The new D Series crawler excavators share the CASE Intelligent Hydraulic System of the previously launched new generation models. The improved D Series system with High Performance Hydraulics Control offers enhanced controllability and smooth operation, the company added.
The new models deliver faster cycle times because of the new electronically controlled hydraulic pumps and larger main valve, which increase their productivity. The new pumps and bigger valve improve the machine’s responsiveness, resulting in cycle times up to 12% faster than that of the previous generation. In addition, the new models deliver a greater lifting power.
The high productivity is further enhanced by the crawler excavators’ excellent autonomy, resulting from the high capacity fuel and AdBlue tanks, combined with the machines’ fuel efficiency. The AdBlue tank only needs to be refilled every 10 fuel refills, so time is not wasted.
