Considering the weather in Caborca is going to be 104F today, this spec was probably a consideration: "Don’t let the temperature stop you from working. The excavator has a standard high-ambient temperature capability of 52° C (125° F) with de-rate and cold start capability of –18° C (0° F). An optional – 32° C (–25° F) cold start package is available"
Nice rig. I've seen them at a training school along the New Jersey Turnpike. They move a lot of ore in a hurry.
