After anchoring yourself and fixing the climbing rope for the second, it's your job as the leader to begin hauling (fig. 11-32):

1. Attach a pulley, through which the haul line passes, to the anchor.

2. Attach an upside-down ascender to the haul line on the haul-sack side of the pulley. The end of the ascender closest to the pulley (normally the bottom) is clipped into the anchor, while the end pointing toward the haul sack is counterweighted with the remains of the rack (or another weight).

3. Attach a second ascender, in the normal direction, to the haul line on the opposite side of the pulley (between yourself and the pulley). Use a daisy chain to connect this ascender to your harness.

4. Push back from the wall using your legs and palms; your body weight will raise the haul sack. When you stop pushing, the upside-

Inverted Ascender Haul

Fixed climbing rope down ascender acts as a brake to prevent backward slippage of the haul bag. You'll need a little slack in the climbing rope between yourself and the anchor to allow your hauling movement.

You can also haul by allowing slack of 6 to 8 feet between you and the anchor. Then, with the daisy chain connected between your harness and the haul line ascender, walk down the wall 6 to 8 feet until the anchor rope tightens. Climb back to your original position by stepping upward in etriers attached to the anchor, pulling the ascender with you. Repeat the process.

This method is also used if two people are needed to lift a very heavy bag. Both of you clip to the ascender on the haul rope, give yourself 6 to 8 feet of slack, and walk down the wall together. Regardless of the method used, always connect yourself to the anchor with the climbing rope.
