What are the types of scrapers?
Scrapers come in two forms: motorised wheel tractor or drawn/towed scrapers. Drawn scrapers are attached through a tow mechanism usually to an Articulated Dump Truck (ADT) or a tractor/dozer, but in Earthmoving applications, nearly all scrapers are so called wheel tractor-scrapers (or motorised) Caterpillar machines.
How much do pull scrapers weigh?
Pull scrapers can weigh thousands of pounds, with capacities ranging from just a few cubic yards on up to 63 cubic yards (48 cubic meters) in the case of K-Tec’s giant 1263 ADT. Many have rear hitches and can pull other scrapers behind them to operate in tandem or in a train.
Are scrapers a cost effective investment?
Scrapers are a cost effective investment. In many applications, one scraper can replace an excavator, 1-2 haul trucks, and possibly a compactor and/or dozer. With a good operator, the machine never stops for loading or dumping, which is why scrapers can achieve the lowest cost per cubic meter of dirt to move.
What is a wheel tractor scraper?
Drawn scrapers are attached through a tow mechanism usually to an Articulated Dump Truck (ADT) or a tractor/dozer, but in Earthmoving applications, nearly all scrapers are so called wheel tractor-scrapers (or motorised) Caterpillar machines.
