History and service record of 320D L to 323D L

Three swing radii. Equipment World reported Caterpillar introducing three mid-sized hydraulic excavators, each with a different swing radius: the 320D L with a standard swing radius, the 320D LRR with a reduced swing radius and the 321D LCR with a compact radius. Caterpillar introduces three mid-sized hydraulic excavators, Equipment World.
Many versions of the 320D. A reply in a Heavy Equipment Forums thread on a 320D says there are about 30 different versions of the 320D, so the serial number matters when comparing machines. The same thread has another poster warning that the common rail fuel system runs at very high pressure and that the high-pressure side should not be opened without training. Cat 320 d, Heavy Equipment Forums.
Cabs. Equipment World's report on the launch says a new, spacious cab promotes operator comfort in the 320D L and 320D LRR, and that a new cab layout aids operators in the compact radius 321D LCR. Caterpillar introduces three mid-sized hydraulic excavators, Equipment World.
