Caterpillar has introduced three new midsize hydraulic excavators: the 320D L with standard swing radius; the 320D LRR with reduced swing radius; and the 321D LCR with compact radius.
The new D-Series machines feature greater performance and versatility than the C-Series machines they replace. The new excavators also feature the Cat C6.4 engine with ACERT technology for fuel-efficient operation and emissions compliance.
