Overview
Scrapers, one of the biggest pieces of equipment you'll find on a construction site, scrape the top layer of the surface and level it out to prepare for further construction. Robert LeTourneau is known for inventing the first earthmoving device, the tractor towed scraper, in 1923. The four primary scrapers are single-engine wheeled scrapers, dual-engine wheeled scrapers, elevating scrapers, and pull-type scrapers. These scrapers can all perform other activities like excavation, leveling, loading, hauling, dumping, and cutting to grade.
