Abstract

Dispositivo de bloqueo para sujetar elemento de desgaste en un soporte en una máquina de movimiento de tierras. El dispositivo de bloqueo se introduce en un alojamiento, y comprende: elemento de bloqueo, elemento interno, medios de desplazamiento para desplazar el elemento de bloqueo entre una posición replegada y una posición extendida, y medios elásticos que, en la posición extendida, ejercen una fuerza tendente a aproximar el elemento de bloqueo al elemento interno.Locking device for holding a wear element in a support on an earthmoving machine. The blocking device is inserted into a housing, and comprises: blocking element, internal element, movement means for moving the blocking element between a retracted position and an extended position, and elastic means that, in the extended position, exert a force tending to bring the blocking element closer to the internal element.
