Abstract
Carretilla de mano eléctrica mejorada para subir o bajar escaleras, tal como una carretilla para cargas o un sillón de ruedas para discapacitados, que permite una mejora en la maniobrabilidad y estabilidad del aparato, así como la comodidad del conductor, especialmente en su manipulación por escaleras estrechas y en los giros de los rellanos de escalera. Consistente en un sistema formado por un tren de ruedas (5) conocido por su aptitud para subir o bajar escaleras, que puede moverse y situarse tanto como en una posición de carretilla clásica (1), como en una posición (2) por debajo del chasis (4) y de la pala (21) lo que facilita su manejo por escaleras. Un asidero bajo (7) y otro alto (6) sirve para sujetar la carretilla en distintas inclinaciones. Un solo motor eléctrico mueve las ruedas y cambia de posición el subchasis (17) que contiene las ruedas.Improved electric hand truck for climbing up or down stairs, such as a forklift or a wheelchair for the disabled, which allows an improvement in the maneuverability and stability of the device, as well as the driver's comfort, especially when handling stairs narrow and in the turns of the stair landings.
