In the argument of 1 large machine vs. 2 smaller machines, one must also consider the fact that the larger machines are built to handle the conditions they work in. Sure (2) 345's could probably keep up with 1 385, but that 385 is built for quarry specific work. It may never have any structural problems whatsoever, only preventative maintenance whereas a couple 345's could develop premature wear in the boom, stick, and bucket linkages due to the extreme service they've been thrown into, thus reducing their service life. Unscheduled repairs get expensive very fast, as well as every aspect of maintaining 2 machines, transporting 2 machines, insuring 2 machines, and fuel consumption of 2 machines. If there wasn't a market for these big pieces, Cat wouldn't be making them.
