An improved robotic power grapple having the capability to both manipulate and impact objects. The grapple has a head assembly (43) containing pivotal jaws (34, 34') and an impact hammer (29) disposed within a rotation means (33) to allow the head assembly (43) and jaws (34, 34') to rotate about a central axis (41). An impact rod (39) extends through the rotation means (33) and through an opening (53) in the tips (37, 37') of the jaws (34, 34') to permit impaction of objects proximate the opening. In combination with an articulated boom (10) and orientation means (42), the improved grapple may be utilized in severe-duty foundry operations to remove gates and risers from foundry castings.

La présente invention concerne un grappin robotisé perfectionné capable aussi bien de manipuler que de percuter des objets. Le grappin comporte un ensemble tête (43) pourvu de mâchoires pivotantes (34, 34') et d'un marteau de percussion (29), monté dans un organe de rotation (33) de façon à permettre à l'ensemble tête (43) et aux mâchoires (34, 34') de pivoter autour d'un axe central (41). Une tige de percussion (39) traversant l'organe de rotation (33) et un orifice (53) dans les pointes (37, 37') des mâchoires (34, 34') permet la percussion d'objets situés au voisinage de l'orifice. Associé à une flèche articulée (10) et un organe d'orientation (42), ce grappin perfectionné convient particulièrement à l'utilisation intensive en fonderie pour enlever les attaques et masselottes dans les coulées de fonderie.
