Evolutions in Machine Technology - Technology has advanced in the traditional mechanical aspects of equipment

摘要

Typically, when we think of technology, we think of information technology: sexy, digital innovations such as telematics or GPS grade-control systems. On a recent trip to a remote west-Texas desert ranch, I was reminded that technology comes in many less glamorous forms. I was visiting the ranch with my uncle, and one of our chores was to replace the generator on a 1967 Caterpillar D7E dozer. This 44-year-old machine carrying the same model designation as our 2010 Cat D7E with "hybrid" technology in the form of diesel-electric drive drove home for me just how much technology has evolved over the past few decades.
