Abstract

UN PIROTE PORTADOR (10) QUE ES VERTICALMENTE MOVIL POR UN TERMINAL SERVOMOTOR ELECTRICO (14) UNA HELICE PALANQUETA RELATIVAMENTE LARGA (15), TIENE UNA FUERZA DE CONTRAPESO SUSTANCIALMENTE CONSTANTE MANTENIENDO EN ELLA PRESCINDICENDO DE EL TANTO SI ES MOVIDO ARRIBA O ABAJO. ESTO EVITA COMPRESION O TENSION DE LA HELICE PALANQUETA. LA FUERZA DE CONTRAPESO ES MANTENIDA SUSTANCIALMENTE CONSTANTE A LO LARGO DE LA CARGA SENSIBLE EN EL PIROTE PORTADOR (10) POR INTERMEDIOS SENSIBLES (17) Y USANDO LA CARGA PERCIBIDA A VARIAR LA PRESION HIDRAULICA APLICADA A UN PISTON (24) CON UN CILINDRO HIDRAULICO (25) Y CONECTADO A LO LARGO UNA CADENA (18) A LA HELICE PALANQUETA (16) A APLICAR LA FUERZA CONTRAPESOS.
