1TESTS MATERIAL AND CAVE RESCUE TECHNIQUES By Christian Dodelin from France5° meeting cave rescue in Croatia
2The first searches concern the stretcherSwitzerland (1997)Civière Castin (1976)FranceStretcherCivièreCamillaMacaNosilaNoszeRettungstrage …Great Britain (1997)Romania (1999)Steinberg – Italia (2000)
3STRETCHERS in France, TSA (1997) Castin (1978) from (Dr) Castin to the Nest by PetzlWe pass by TSA of G. MarbachNest (2011)The dates are those of pictures
4Petzl is doing the material specific for caving, bringing more safety andfinding solutions for jammer,descender and pulley.The conditions in the cave are hardwith water and mud.In seventies G. Marbach published« Techniques Speleo alpines »He tests and studies the different typesof ropesKnotsAnchorages…In « Spelunca », national publication inFrance, we find articles about tests onthe new material.
5In eighties, in vertical way, we use : 2 ropes (traction and safety)The traction was only palanThe deviation pullies were fixed on the rockTo extract the pullies we had :to take in charge the stretcher onone rope and keep other free justa short time and take of one pulley.Later we changed the tension onthe rope for other pulley.2 teams at the top for each rope.The leader coordinate the exercise
6Before the end of eighties : With the Italian Knot we have releasable pulleyWe use several knots for anchorageWe test new prototype of pulley and agree thesystem hauling with counterweightWe use only one rope to support the stretcheron tyrolean
7TESTS by SSF on techniques and materials of cave rescue 1994 – 1996 – 2005 in laboratory of PETZL Establishment, at Crolles, France
8We got informations during several minutes from 2 dynamometers in the same timewith registration on computer.We could have informations before, duringand after a fallWe can put the material in the same configurationthan in rescue operationWe took some used material of 2 ,5,10, 15 years.(Ropes, carabineers, jammers, pullies,descenders,...)On short distance the condition wereunfavourable.
9We tested : the three load sharing anchors, eight knot, rabbit knot, stopper knot,Changing the ropes with different diameters , ages,statics or dynamic, dry or wet,…We tested different hauling techniques : Palan,Counterweights, tyrolean and different solutionsfor the tension of the rope….
10We could see the capacities and limits of the different equipments and theirpossibilities using.
11Informatics report is published in French Inside the « cave rescuer’s manual,We have some results and techniqueindications
