Mechanical Advantage: Picking Your Haul Ratio

Understanding mechanical advantage is the key to mastering wall hauling. A simple 3:1 system is the standard for most hauls, providing a good balance between speed and effort. However, as the weight of the bag increases or friction grows due to rope stretch and edge contact, you may need to step up to a 5:1 or 6:1 system.

To build a 3:1 system, attach your progress capture pulley at the anchor and use a secondary ascender on the haul line attached to a pulley on your haul bag. A 5:1 system adds a third pulley to the chain, drastically reducing the pull force required at the cost of requiring more rope to be pulled through the system. Always weigh the physical energy you save against the increased complexity and rope travel required for higher ratios.

Ultimately, experiment with your setup at a local crag before committing to a multi-day wall. If you find yourself consistently struggling to move the bag, move to a higher mechanical advantage, but remember that simpler systems are usually faster to manage. Balance your technical needs with your ability to troubleshoot the system when things go wrong.

Rope Management Tips to Prevent Haul Line Snags

Haul line snags are the most common cause of frustration and delay on big walls. To prevent them, always ensure the haul line is coiled cleanly and kept away from sharp flakes or rock features. Using a dedicated haul bag swivel can prevent the rope from twisting, which significantly reduces the chances of the line snagging on itself.

When setting up your haul, use a rope protector or a padded tarp at the base and over any sharp edges along the route. High-quality rope guards or even sections of old fire hose can protect both your haul line and the rock face. A clean rope path is far more important than the specific brand of pulley you choose to haul with.

Finally, communicate clearly with your partner when the bag is stuck. Do not attempt to force a snagged rope, as this can lead to core damage or damage to the anchor. Pause, assess the line from the belay, and use a haul-bag tag line to steer the load away from obstacles.

Inspecting and Maintaining Your Hauling Devices

Hauling devices take a tremendous amount of abuse and require regular inspection to ensure peak performance. Check all pulleys for smooth rotation and look for any signs of metal fatigue or hairline cracks in the side plates. If a pulley stops spinning freely under no load, it likely requires cleaning or lubrication, which should be done according to the manufacturer’s instructions.

Inspect the cam teeth on your progress capture devices regularly for debris and wear. Accumulated dirt, rock dust, and resin can degrade the effectiveness of the teeth and lead to rope slippage. Use a soft brush to clean the cam and ensure that the spring mechanism returns the cam to the locked position crisply every time.

Replace any device that shows signs of significant impact damage or excessive wear, as structural failure while hauling is a serious safety risk. Maintain a log of your heavy-use gear to track its service life over time. A well-maintained hauling system is not just safer, it is significantly more efficient, keeping you moving smoothly toward your objective.

Big wall climbing is a pursuit that demands as much from your mind as it does from your gear. By selecting the right hauling system and maintaining it with care, you turn a logistical challenge into a seamless part of the adventure. Focus on the mechanics of your ascent, respect the weight of your goals, and above all, enjoy the unparalleled perspective that only a life on the wall can provide.
