Patent ID: 7241101

Claim:
A double action grab fork comprising: (a) upper grab member having an upper grab end and an upper grab body; (b) lower grab member having a lower grab end and a lower grab body, wherein the upper grab member is not directly attached to the lower grab member; (c) arm having an upper end and a lower end, wherein: (i) the upper end of the arm is rotatably attached to the upper grab body to allow rotation of the upper grab member relative to the upper end of the arm; and (ii) the lower end of the arm is rotatably attached to the lower grab body to allow rotation of the lower grab body relative to the lower end of the arm; (d) hydraulic cylinder attached to the upper grab member and the lower grab member, wherein the upper grab member, the lower grab member, and the arm are constructed to move through a lever action and a rotation action as a result of extension or refraction of the hydraulic cylinder, wherein the lever action results by rotating the arm relative to the lower grab member, and the rotation action results by rotating the upper grab member relative to the arm; (e) a rotation arm having a first rotation arm end and a second rotation arm end, the first rotation arm end being non-rotatably attached to the upper grab body, and the second rotation arm end comprising a rotation arm hydraulic cylinder connection for attaching the rotation arm to the hydraulic cylinder; and (f) wherein the combination of the lever action and the rotation action allows the upper grab member to reach out and draw material into the lower grab member.
