Scrapers are large earth-moving machines generally utilized in mining operations, but can be utilized in many construction situations (see picture left). It is best to use scrapers for short hauls, and when the cut and fill areas are large enough to accommodate the scraper, as the length of the machine is considerable.
Scrapers work by driving on top of the site that needs to be dug. A large receptacle on the rear of the machine, known as the bowl, is lowered into the ground hydraulically. As the scraper is driven forward, the bowl becomes filled with soil. The bowl’s capacity can range from between 10 to 44 cubic yards (8-34 cubic meters). Once full, the bowl closes and the load can be moved safely to the dump site.
Properties of Scrapers
Scraper tires, of which the wide base type is most common, should have the same properties as those for dump trucks, that is high heat and wear resistance. Superior flotation and traction are also occasionally required.
