Abstract
Perfeccionamientos en una carretilla eléctrica industrial, caracterizados porque ésta comprende una par de unidades de dirección y tracción, cada una de ellas provista de un motor accionador, dispositivos controladores de los motores provistos de elementos de cierre de circuitos para determinar la dirección y velocidad de cada motor, dispositivos de montaje de una palanca de accionamiento manual para su movimiento con relación a los dispositivos de cierre de circuitos, medios accionados por el movimiento de la palanca para accionar a su vez los dispositivos de cierre de circuitos, y la construcción de los dispositivos accionados por la palanca siendo tal con relación a la construcción y colocación de los dispositivos de cierre de circuitos que el movimiento de la palanca efectua el accionamiento de los dispositivos de cierre de circuitos para accionar los motores a la misma o diferentes velocidades y en igual u opuestas direcciones.
