Parallel Plaquettes:
A lightweight rope rescue system using common climbing equipment
A current review of rope rescue systems reveals a wide variety of techniques,
equipment and risk management philosophies relative to moving live loads over
complex terrain. Some teams use a single main line and a separate belay line;
others employ the use of two mainlines to support the load without a separate
belay. Descent control device choices run the gamut and include brakeracks,
cammed devices, 8 plates and belay tubes just to name a few; rescue belay
devices/systems are also numerous and include Tandem Prusiks, the Traverse
540° Rescue Belay, the Petzl I'D as well as several other devices. While some
teams may elect to employ the use of single rope technique in certain
circumstances, others would rarely move a live load without the use of a
backup belay system.
The reasons for the diversity in all of these subject matters include terrain,
regional influences, culture, typical number of respondents, skill and training
levels, cost, weight, commonality of equipment, perceived levels of risk, type
and size of agency and many other considerations. The nature of the task is
improvisational. Because of that quality, the solutions will always require
judgment and that alone will ensure a certain level of diversity amongst
'common industry practices'.
One 'big picture' theme that seems to be pretty well agreed upon amongst
practitioners is:
1. having system-wide auto-stop in place
(i.e. the system does not require a human operator to hold or grip something in
order to maintain security)
The Parallel Plaquettes system is currently being examined as a potential option
to meet that key rope rescue principle. The system was not designed for all
rope rescue groups for reasons discussed above. For example, it is not
compatible with 12.5mm rope. However, for those operating in a mountain
rescue environment using smaller diameter rope it has the benefit of being
constructed with ubiquitous gear that is likely already hanging from your
harness.
