- Used in conjunction with skid lifts. When skids are raised by means of their lift, the forward upper corners of skids extend over 1 in. above top of carriage head brooks, forming fulcrum point to turn log when it is pulled backward by hook arm. Hook is thrust down into the log by motion of piston in hook arm cylinder being reversed. Continued reverse motion pulls log backward toward heel formed by skids, turning it and exposing new surface to saw. Hook arm works loosely on shaft, and on its upward stroke engages jaw clutches which are keyed to shaft, raising push and helper arms into a position to hold log while turning, and push it back onto carriage head blocks. Push and helper arms keyed solid to shaft and operated by push arm cylinder. Size of logs handled depends on carriage opening: 10 in. (25 cm.) turner recommended for opening 60 to 72 in. (1.5 to 1.8 m.), 12 in. (30 cm.) for 72 to 84 in. (1.8 m. to 2.1 m.), 14 in. (36 cm.) for openings over 84 m. (2.1 m.).
