Diseño y construcción de un prototipo de elevador de acceso para personas con movilidad reducida en buses de transporte urbano.

Abstract

This work involves the design and construction of a platform lift of people with disabled for entry into the urban buses, as an initial stage, it investigated access conditions (height of sidewalks) in urban bus stops and points taken into account in the development work. The lift was designed based on a four-bar mechanism which connects two platforms which normally function as tier access to the interior of the bus, in order to maintain the standard stands system. The design proposed the deployment of a platform that goes down to the sidewalk to pick up the person and allow raising the floor level on the bus. The system works with pneumatic energy and pneumatic accessories, for easy mounting in urban buses, it performs all technical and safety specifications required in the Ecuadorian standard NTE INEN 2205 Urban Buses. For ease of operation has included the necessary signage located in actuating two valves, one controls the raising and lowering of the elevator while the other controls the display of the platform. To verify the proper design and operation of each component of the elevator, it used computational tools that verified the mechanical and system operating conditions. The cost of the elevator is economical and easy to use, unlike other existing systems can be incorporated into urban buses in the future, as indicated by the national rules and regulations.
