Abstract

Sistema que comprende un conjunto de dispositivos de potencia hidráulica bidireccionales (308, 310) y un controlador (104) capaz de limitar de forma variable las respectivas presiones hidráulicas máximas con las que el conjunto de dispositivos de potencia hidráulica bidireccionales (308, 310) puede mover selectivamente elementos de pinza respectivos (114, 300) en un movimiento de cierre, acercándolos entre sí, en un movimiento de apertura, alejándolos entre sí, o en un movimiento de desplazamiento lateral al unísono entre sí, presentando el controlador (105) una o más válvulas reguladoras de presión (200, 202, 204) que se pueden interconectar con dicho conjunto de dispositivo de potencia, y pudiendo dichas válvulas reguladoras de presión, en respuesta a una selección de presión máxima de desplazamiento lateral, limitar de forma variable una presión máxima de desplazamiento lateral con la que dicho conjunto puede producir dicho movimiento de desplazamiento lateral, caracterizado porque dicho controlador incluye al menos una disposición de anulación (220, 240, 242, 252, 254) capaz de anular dicha selección de presión máxima de desplazamiento lateral y así reducir automáticamente dicha presión máxima de desplazamiento lateral en respuesta a dicho movimiento de apertura de dichos elementos de pinza.
