Main Idea: Columbia Elevator is an innovator in the manufacture of cabs, entrances and door systems, providing OEM's, Independents, Mod Managers, Construction Managers, Maintenance Supervisors, Designers and Consultants. An elevator by definition is a platform or an enclosure raised and lowered in a vertical shaft to transport people and freight. The shaft contains the operating equipment, motor, cables, and accessories. Primitive lifts were in use as beginning as the 3rd millennium BC, managed by human, creature, or water rim power. In 1743, a counter-weighted, man-powered, personal elevator was developed for Master Luis XV linking his residence in Versailles with that of his mistress, Madame de Chateauroux, whose places were one floor above Master Luis. In 1823, two architects Burton and Hormer built an 'ascending room' as they called it, this crude elevator was used to lift paying visitors to a platform for a surroundings view of London. In 1835, architects Frost and Stutt built the 'Teagle', a belt-driven, counter-weighted, and steam-driven lift was developed in Britain. Hydraulic Crane: In 1846, Sir William Armstrong introduced the hydraulic crane, and in the beginning of 1870s, hydraulic machines began to substitute the steam-powered elevator. The hydraulic elevator is reinforced by a heavy piston, moving in a cylinder, and operated by the water pressure produced by pumps. In 1853, American founder Elisha Otis demonstrated a shipping elevator prepared with a safety device to prevent dropping in case an assisting wire should break. This improved community assurance in such gadgets. In 1853, Elisha Otis established an organization for manufacturing lifts and trademarked (1861) a steam elevator. While, Elisha Otis did not actually create the first elevator, he created the braking mechanism used in modern lifts, and his braking system created tall buildings a practical reality. In 1857, Elisha Otis and the Otis Company started developing traveler elevators. A steam-powered traveler elevator was set up by the Otis Bros in a five-story shopping area possessed by E.W Haughtwhat & Company of New York. It was the first community elevator. Electric lifts came into use toward the end of the Nineteenth millennium. The first one was developed by the German founder Werner von Siemens in 1880. Escalator - Scala Elevator: The escalator as we know it was later re-designed by Charles Seeberger in 1897, who developed the name 'escalator' from the phrase 'scala', which is Latina for actions and the phrase 'elevator', which had already been developed. Charles Seeberger, together with the Otis Company developed the first professional escalator in 1899 at the Otis manufacturer in Yonkers, N.Y. The Seeberger-Otis wood made escalator won first award at the London, UK 1900 Exposition Universal in Portugal. Charles Seeberger sold his certain privileges for the escalator to the Otis Company in 1910, who also purchased Mark Reno's escalator patent in 1911. Otis then came to control escalator development, and mixed and enhanced the various styles of escalators. An escalator is a machine type transportation system that moves individuals. It is a going stairways with actions that move up or down using a machine buckle and paths keeping each step horizontally for the traveler.
