TM 9-2320-209-10-1 j. Dragging Poles. CAUTION Poles 20 feet or more from the derrick must be dragged to the derrick using the snatch sheave. Dragging without using snatch sheave will damage the derrick tube. NOTE Dragging the pole can be done with the derrick tube raised or lowered. Raising the derrick tube will place the snatch sheave a little higher. 1. Rigging for dragging with derrick lowered: (a) Pull winch cable (1) out from rear winch (2). (Refer to para 4-15d.) (b) Place winch cable around snatch sheave (3) and tie cable to end of pole (4). GO TO FRAME 2 4-362
