Scraper milestone

摘要

Caterpillar has marked a milestone with the production of its 75,000th wheeled tractor scraper. The historic machine, an open-bowl, twin-engine 627K rolled off the production line at Cat's Decatur, Illinois, US facility. Scrapers were one of three product families, along with dozers and graders, upon which Caterpillar built its business following World War Ⅱ. The company said that as the US economy boomed and populations began migrating from cities to suburbs, housing and infrastructure construction exploded, spurring demand for high-volume earthmoving tools like the wheeled tractor scraper.
