For over a 12 months I’ve caught a number of social media posts of extremely licensed guides belaying their shoppers non-traditionally with a Progress Seize Machine or “PCD”. This system has crept into the leisure climbers device package and for good motive, it has some actual actual benefits over belaying with a extra conventional plaquette (Black Diamond Information ATC, Petzl Reverso, DMM Pivot) or the widespread Assisted Braking Units “ABDs” the Petzl Gri Gri 2, Petzl Gri Gri+, the brand new Petzl Neox.
Selecting to belay with a PCD must be an knowledgeable and aware determination and I hope this publish provides you with a few of the info you need to take into account when making that call. The most important piece of this puzzle merely comes all the way down to acceptable terrain.
- Terrain– This system is best suited of belaying a second in 4th and simple fifth class terrain the place the chance of a fall is low and the climber is shifting at the next charge of pace. Principally if the second isn’t shifting sooner then 1 meter a second (3 toes a second) you possible ought to belay with a extra conventional methodology like a plaquette or ABD.
- Handle Slack– It’s crucial with any “toothed” PCD to have minimal slack within the system because the second is climbing. This must be manageable given the shortage of resistance when pulling rope, particularly by way of the Petzl Nano Traxion and Petzl Micro Traxion. All three of the PCDs I hyperlink beneath have technical documentation that point out a load over 4kN or extra will result in sheath injury. If slack is eliminated whereas the second climbs, particularly in direction of the top of the pitch when there may be much less dynamic rope within the system, it must be straightforward to keep away from a 4kN load on the PCD.
- Have Improvised Rescue Expertise– This level is effectively illustrated by the quantity of climbers who use plaquette fashion units (Black Diamond Information ATC, Petzl Reverso, DMM Pivot) however have but to follow decreasing from a loaded gadget. As talked about earlier utilizing a PCD to belay a second must be in terrain the place a fall or decrease just isn’t anticipated. If both of these two issues might be wanted I’d possible select a special belay approach, nonetheless, surprising does occur. In case you are skilled sufficient to belay your second with a PCD you need to have a strong understanding of release-able load transfers. It is best to have the talents to swap a loaded PCD with one thing that might enable a clean decrease (Munter Hitch, LSD, Gri Gri, and so on). Making this transition safely and easily is one thing finest realized from a professional information or teacher. (These expertise are coated and practiced in my customized Self Rescue Course, ship a message if enthusiastic about that curriculum).
A Comparability Have a look at Three PCDs
* Appropriate with the PUR’LINE 6 MM twine just for hauling a pack
* Appropriate with the RAD LINE 6 MM twine (extra info within the Directions for Use at http://www.petzl.com)
The Petzl Tibloc is clearly the lightest and most reasonably priced of the three Petzl PCDs I’m evaluating right here. It’s effectively established as a superb ultralight weight gadget for glacier journey, crevasse rescue, and improvised rescue. The addition of the spring loaded mechanism to provoke seize on the latest mannequin of the Petzl Tibloc means it could possibly work as a belay for a second, nonetheless, the shortage of a pulley means you’ll really feel noticeable extra resistance when pulling slack by way of the system. For that reason alone I feel it’s price contemplating one of many different two choices from Petzl, particularly now that there’s a selection that weights solely 16 grams extra. Moreover, care must be used when putting in the Petzl Tibloc to insure the rope passes by way of the locking carabiner and never simply the gadget!
The Petzl Nano Traxion, whereas costing twice as a lot because the Petzl Tibloc, has lots going for it. First, it incorporates a extremely environment friendly (91%) pulley, which makes pulling in slack, no matter diameter, fairly easy. At solely 53 grams it’s the lightest PCD + Pulley I’ve ever examined. Paired with a Petzl Rocha SL Carabiner and a house tied keeper twine this arrange has develop into the latest version to the again gear loop on my harness.
The Petzl Micro Traxion is the costliest and heaviest of those choices. The one actual benefit of this mannequin is the added mechanism that means that you can lock the cam within the open place so you should use the gadget as a easy pulley. It’s a reasonably small addition to justify the extra value and weight over the Petzl Nano Traxion.
Appropriate Carabiners
My favourite carabiner for all three of those PCDs is the Petzl Rocha SL Carabiner. This small light-weight locking carabiner includes a purple indicator that aids in visually confirming whether it is locked or not and a small gap for attaching a keeper twine to any of those units. I’m additionally a fan of the Petzl OK Triact Auto Locking Carabiner and the Petzl OK Ball-Lock Carabiner particularly when matched with the Petzl Tibloc.

Abstract
Climbing methods proceed to evolve with advances in methodology typically taking place on the highest ranges of the game (licensed climbing guides and accredited organizations) after which disseminate to the extra common practioners. Belaying with a PCD can result in effectivity and elevated security in sure climbing conditions. Have in mind the selection must be effectively knowledgeable and take into account; terrain, managed slack, and your skill to drawback remedy unlikely situations like needing to transition to an surprising decrease. In the event you do end up in conditions the place this system would give you the results you want take into account including the Petzl Nano Traxion and Petzl Rocha SL Carabiner to your package.
