Abstract

Procedimiento de determinación de los emplazamientos de los dos gatos hidráulicos de mando de un conjunto de dos brazos articulados, el primer brazo, llamado aguilón, articulado sobre el bastidor de un ingenio de obras públicas, tal como una cargadora o una pala hidráulica, el segundo brazo llamado balancín, articulado sobre el primer brazo mientras que un cangilón susceptible de descansar en el suelo durante su carga, va acoplado a dicho balancín, que cada uno de dichos dos gatos está acoplado entre el bastidor y el balancín, uno al menos de los ejes de enganche de un gato siendo distinto del eje de enganche del otro gato sobre el mismo elemento bastidor o balancín y que los centros instantáneos de rotación del cangilón corresponden respectivamente al funcionamiento de cada uno de los gatos del mando cuando el cangilón se halla cerca del suelo, son elegidos sobre el eje longitudinal del aguilón, caracterizado porque se elige el segundo centro instantáneo de rotación sensiblemente de aplomocon la posición del cangilón descansando en el suelo en el momento de su carga y porque se coloca los ejes longitudinales de los gatos de mando sobre radios pasando respectivamente por cada uno de dichos centros de rotación los ejes de enganche de los gatos al balancín y al bastidor siendo determinados por las intersecciones de dichos radios con cada uno de dichos radios con cada uno de dicho elementos.
