A double-acting hydraulic cylinder between the gripper carrier and the cutterhead support. Extending, the thrust cylinders push the cutterhead into the rock through one boring stroke; retracting, they pull the gripper carrier forward for the next. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.
