The LeTourneau Buggy

摘要

Robert G. LeTourneau was the leading advocate of high-speed, high-capacity, mobile earthmoving machinery, and his numerous inventions spearheaded the concept. His interest in such equipment stemmed from his own experience as an earth-moving contractor; machines that were available to him in the early 1920s simply did not suffice for the tasks at hand, so he designed and fabricated his own.One of his innovations was the large, wheeled dump wagon. Small dump wagons had been used for decades behind horses and mules, and most were bottom dumps. Larger wheeled bottom-dump wagons for use behind steam traction engines followed, then crawler-mounted dump wagons for use behind crawler tractors.
