GRAPPLE IMPACTOR

摘要

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.
