Abstract
Abstract There is disclosed a dumping scraper-barrow in which raising of the scoop to dumping position is effected by pulling one of the handles towards the other thereby actuating a linkage connecting the handle to the back of the scoop. The users thereby are enabled to raise the scoop or even to adjust the angle during scraping by simply squeezing together with his arms without the necessity of letting go of one of the handles. The arrangement also gives the users plenty of leverage for raising the scoop when the same is loaded down with material to be dumped.
