One of the most popular ways to move the plastic waste and load the shredder with the waste is the gripper. The wear on the gripper by the movement of the plastic waste is low, with a large portion of the wear occurring at the tips of the gripper where it slides on the ground.
The materials recommended are Hardox HiTUF or Strenx 700 for the body of the gripper, where Hardox 500 cutting edges should be used.
