dc.description.abstract | Stem was also used to power other construction equipment. The first documented application occurred in the United States in 1838 when William Otis produced a steam-powered shovel for railroad works. The next documented use was Eli Blake's jaw-type rock crusher, built in Connecticut in 1858 to produce stone for pavements. The Blake crusher could produce about 5 m' of broken stone per hour, which far exceeded the output achieved by breaking by hand. Animal power was used tor earthworks via hourse- and ox-drawn plows, scoops, scrapers, spreaders, levelling drags, and carts. In particular. earthmoving had been by hand-carried baskets panniers', wheelbarrows, and carts. The u heelbarrow was invented in China in about A. D. WO and took another millennium to reach Europe. Benjamin Colt trom California produced a usable steam-powered tractor in 1885, as a prelude to introducing the gasoline-powered crawler tractor with self-laying tracks in 1904. A tractor with a forward blade, the now famous bulldozer, was first used in 1923. Hydraulic controls for the blade were introduced in 1925. | eng |
