This is my Cat 345 MH Material Handler. It is a highly modified version of 8043, and uses parts from
42006. It uses no extra motors or electronics. The boom and elevated cab area were completely redesigned from scratch. it retains the same functions as the original 8043, but the shaft that powered the bucket actuator now powers the orange peel grapple. The grapple is also free floating and rotates 360 degrees, but the rotate function is not independently contolled. It will only rotate under power when the actuator cannot move and the open/close Grapple button is used.
If for instance you pick up an object and need to rotate it, just hold down the close grapple button until it rotates. It uses a friction drive to keep it from spinning out of control, due to the high rpm's needed for the grapple actuator.
