I'D S
The I'D S is a professional abseil rescue device and semi-automatic belay device from the manufacturer Petzl for industrial climbers and height rescuers for belaying, abseiling, rescuing and ascending with and on single ropes .
Possible uses
- Abseiling : With the I'D S you can abseil at any speed, if you abseil too quickly or if you let go of the control lever, the device automatically blocks the rope.
- Rescue : If used correctly, the I'D S can carry loads of up to 250 kg and thus a rescuer and a casualty at the same time. The rescuer can then abseil together with the victim.
- Securing : Another person can be secured with the I'D S. The operator only has to retighten the rope. If the other person falls, the device blocks automatically.
- Climbing the rope : With the help of a rope clamp, a step loop and a rope pulley, the I'D S can be used to climb the rope.
- Rope clamp : The I'D S can be intentionally blocked at any time for any use and then has the function of a rope clamp.
functionality
The rope is placed around a movable clamping cam in the device and clamped in by a spring mechanism. If the rope is loaded, the cam rotates minimally and continues to clamp the rope. In order to let the rope slip slowly and in a controlled manner for abseiling, the user has to move the clamping cam back a little using the lever on the device.
If the user lets the rope slide too quickly through the component using the lever, the device blocks automatically (anti-panic function). The user has to turn the lever on the device all the way back once to start the abseiling process again.
advantages
- In the event of a fall, the device automatically blocks the rope without the person securing it having to actively stop. This has the advantage that the device can still hold a fall if the belayer does not have his hands on the rope (e.g. because he hits the wall while belaying or is unconscious from falling rocks).
- The belayer can hold a person hanging in the rope without any effort.
- The rope does n't tangle .
- The device is very safe when used correctly.
disadvantage
- The device is relatively heavy compared to the tuber and figure figure eight and only allows certain diameters of a single rope . It is therefore not possible to use double or twin ropes.
Application error
- The rope is put into the device the wrong way round. If the rope were to be subjected to a load, the rope would rush through the device unbraked - if the rope were not blocked by the safety system specially built for this case. In this case the rope is blocked and controlled abseiling is not possible.
Correct operation
- The rope that is loaded is inserted in the middle of the device and comes out again at the top.
- To secure another person, the safety rope is always quickly tightened, the hand remains on the safety rope that comes out of the device at the top.
- If the operator wants his hands free, he must set the lever to "Lock".
- When lowering, the blockage is only released with a closed hand around the safety rope that comes out of the device at the top.
Lever positions
The I'D S has five different lever positions:
- The lever is only set to "store" when the device is not in use.
- If the lever is set to "lock", the rope is blocked. The operator has both hands free, any load rests on the device without any action on the part of the operator.
- In the “belay” position, the rope is still blocked, but ready to be released. The operator must secure the rope that comes out of the top of the device with a clasped hand.
- In the “descent” area, the operator can steplessly regulate the rope and let it slip through the device. The operator must guide the rope that comes out of the top of the device with a clasped hand.
- If the lever is in the "panic" position, the panic function of the device has been triggered. The rope is blocked, the operator must set the lever back to "lock" and can then start the lowering process again.
Classification
The I'D S is classified in the highest class A according to DIN EN 341.
