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.
