Can we rely on devices to slip on ropes at predictable forces given the possible range of physical and environmental conditions? Here we test the Petzl Shunt on several different ropes.
This study has been prompted from a few directions but the key questions are: What is the force required to initiate tearing on some common shock-packs? Does this value change if the unit is wet? Can shock-packs
Shock packs, load limiters, energy absorbers, tear-away lanyards are all terms which refer to a manufactured component that can be included in rope-based systems in order to limit the peak force applied to a falling body. There
