Motor-Grader Technology Hits High Gear

摘要

Although Caterpillar did intensive preparatory homework, we'd still bet that you could have almost heard the company take a corporate deep breath just before deciding to design its new M-Series motor graders without conventional controls, that is, less the two banks of control levers that flank the steering wheel — and, yes, less even the steering wheel. Replacing all those familiar controls are but two multi-function joysticks. Caterpillar's big news, however, is only the most recent in a string of major announcements regarding motor-grader refinement and new-model introductions. Motor-grader manufacturers have been busy.
