TESTS MATERIAL AND CAVE RESCUE TECHNIQUES

By Christian Dodelin from France

5° meeting cave rescue in Croatia

The first searchesconcern

the stretcher

Switzerland (1997)

Civière Castin (1976)

France

  • Stretcher

TSA (1997)

Castin (1978)

STRETCHERS in France,

from (Dr) Castin

to the Nest by Petzl

We pass by TSA of G. Marbach

Nest (2011)

The dates are those of pictures

slide4

Petzl is doing the material specific

for caving, bringing more safety and

finding solutions for jammer,

descender and pulley.

The conditions in the cave are hard

with water and mud.

  • In seventies G. Marbach published
  • « Techniques Speleo alpines »
  • He tests and studies the different types
  • of ropes
  • Knots
  • Anchorages…

In « Spelunca », national publication in

France, we find articles about tests on

the new material.

slide5

In eighties, in vertical way, we use :

  • 2 ropes (traction and safety)
  • The traction was only palan
  • The deviation pullies were fixed on the rock

To extract the pullies we had :

to take in charge the stretcher on

one rope and keep other free just

a short time and take of one pulley.

Later we changed the tension on

the rope for other pulley.

2 teams at the top for each rope.

The leader coordinate the exercise

slide6

Before the end of eighties :

With the Italian Knot we have releasable pulley

We use several knots for anchorage

We test new prototype of pulley and agree the

system hauling with counterweight

We use only one rope to support the stretcher

on tyrolean

slide7

TESTS by SSF on techniques and materials of cave rescue

1994 – 1996 – 2005 in laboratory of PETZL Establishment, at Crolles, France

slide8

We got informations during several minutes

from 2 dynamometers in the same time

with registration on computer.

We could have informations before, during

and after a fall

We can put the material in the same configuration

than in rescue operation

We took some used material of 2 ,5,

10, 15 years.

(Ropes, carabineers, jammers, pullies,

descenders,...)

On short distance the condition were

unfavourable.

slide9

We 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 solutions

for the tension of the rope….

slide10

We could see the capacities and limits

of the different equipments and their

possibilities using.

slide11

Informatics report is published in French

Inside the « cave rescuer’s manual,

We have some results and technique

indications
