Function: Shock
absorbing sling designed to reduce peak loads in any climbing
system!!
Multi-functional energy absorbing device.
Screamers™ will provide added protection in climbing and rescue situations. Screamers not only absorb energy
directly, because of the stitch ripping effect, they also
allow your rope to absorb more energy from the fall by
increasing the time interval of the fall. Screamers can
reduce shock loading in any rescue system. The standard
"Screamer" can effectively reduce peak loads
by 3-4 kN any climbing or rescue system. YATES original
Screamers were first developed over ten years ago, Yates
has since developed numerous variations on the "Screamer"
design with use in Aerospace, Military, and explosive testing
to decelerate various objects.
Screamers were originally designed to be used on less than ideal climbing protection such as small nuts, old
1/4" bolts, snow anchors or marginal protection.
We have determined that the most effective activation
for a standard screamer to be >2kn(550lbf.) for climbing
related situations.
The new "SHORTY" Screamer offers
the exact same properties as the standard Screamer in a more compact package unit. The new "ZIPPER"
Screamer is designed for long falls with high fall factors.
These types of falls occur usually within the first two or three protection placements that are run out. Ice climbing is a good example where the "ZIPPER" is exceptionally effective when used on the first few placements. The "ZIPPER"
can effectively reduce peak loads by 6-8kN in any climbing system. Screamers and Zippers have proven to be very successful in reducing loads to any anchor when it is stressed in excess of the activation force of the Screamer device.
When the Screamer activates, the action of the stitching
ripping produces a loud tearing sound, indicating the
system has reached the activation point of the Screamer
(>2 kN). The activation point of a Screamer is consistently repeatable to +- 5% accuracy. (Screamers are very useful
in documenting maximum loads in a given situation, such
is their use in Rescue.) Screamers can be combined in series and ganged up double or triple to increase the activation force or the total absorption.
