Controlled descent
A descender for both work at height and rescue, access from above is preferable because it allows one to take advantage of the force of gravity.
Descenders are designed to regulate friction and control the descent
on a fixed rope. They allow a worker to position himself at any point on
the rope. Some descenders such as the Petzl I'd can also be used to safely belay a leader using rock climbing techniques.
Ease of use
Self-braking descenders provide ease of use and increased safety when moving on a single rope.
The braking mechanism consists of a pivoting cam which pinches the rope and brakes the descent
when the handle is released.
New for 2009
The new versions of the I'D S and I'D L descenders have a new handle which allows easier movement
over horizontal or low-angle terrain.
I'D D200S0
Self-braking descender with anti-panic function for working on fixed ropes
Designed for work on a rope: the gate on the
swinging side plate helps prevent dropping the
device
Multi-functional handle allows the user to:
- unblock the rope and control the descent with the
hand on the braking side of the rope
- move more easily on horizontal or low-angle terrain
thanks to the button on the handle
- to position himself while on the rope
Anti-panic function is engaged if the user pulls too
hard on the handle: the pivoting cam is released and
automatically brakes to stop the descent
Anti-error safety cam to reduce the risk of an
accident due to incorrect installation of the device
on the rope. The shape of the cam is designed to
improve rope glide during an ascent.
Pivoting cam makes it easier to take up the slack in
the rope Can also be used to make a reversible haul
system, and for short ascents (in conjunction with a
FOOTAPE or FOOTCORD footloop and an ASCENSION handled rope
clamp).
