Introduction

The RIG is a "Compact self-braking descender for experienced users". It was designed for descending a rope, but it is also used for belaying
or back-up belaying. The various uses of the device are given below.
WARNING: certain of the uses presented are specific uses intended for expert users who master these techniques.

Regarding Standards
The RIG is certified to EN 12841 type C for descending a rope of 10.5 to 11.5 mm (EN 1891 type A) with a nominal load of 150 kg. To be in compliance with the EN 12841 standard, the RIG must be used with a type A back-up device (for example, the Petzl ASAP fall arrester) attached to a second rope, called the safety rope.
It is also certified to the EN 341 European standard for rescue on 10.5-11.5 mm rope (EN 1891 type A). To be in compliance with the EN 341 standard, the maximum load is 150 kg (maximum test load in the standard for this type of device).
It is also certified to the American standard, NFPA 1983, 2006 Ed. (light use) when used with a 10.5-11.5 mm NFPA compliant rope.

Rope
Use the RIG with a 10.5-11.5 mm rope having a sheath and core. Ease of use will depend on the rope used. Wash new ropes to remove some of the lubricants used in their manufacture. New ropes can be slippery and thus reduce the RIG’s braking effectiveness. You can be surprised when you switch ropes; pay particular attention to thin or new ropes. At the same time, an old or large-diameter rope can be difficult to use for belaying or back-up belaying.

DESCENDING

Niveau débutantDescending on one strand of rope:

The RIG allows you to descend a rope and to stop. It can be locked in order to have your hands free. You control the descent speed by varying your grip on the braking side of the rope. To descend, pull gradually on the handle. Always hold the braking side of the rope. To stop, release the handle while holding the braking side of the rope.

Niveau débutant Descending on one strand with additional braking :

Ease of descent depends on the wear on the device, on the rope used, and on the load. Using a braking carabiner helps avoid being surprised by the descent speed, for example on a new, thin rope. The braking carabiner provides better control of the descent. The FREINO is a carabiner designed for this purpose. The braking spur should face toward you.

Niveau débutantWork positioning :

When you want to have your hands free for working, use the work positioning mode. You may let go of the braking side of the rope only in
this position. In this position the cam pinches and jams the rope. The device is locked on the rope. To go into work positioning mode with hands free, lock the device on the rope by moving the handle in the direction opposite to that used for descent (turned to position B). This position is very useful, for example when you are working on an inclined surface with the device lightly loaded.

AID / RESCUE


Niveau expert
Accompanied descent, self-rescue by a team-mate (device on the harness)
Exceptional use: maximum load 200 kg.
These techniques must only be executed by experienced users who are trained in their proper application. For loads exceeding 150 kg, the rope used (type, condition, diameter, etc.) has a significant effect on the RIG's performance. Practice with your rope and be especially careful with new ropes. The RIG allows partner rescue from the harness. The first technique presented is a counterbalance technique, many other techniques exist
involving haul systems or cutting the rope. When transferring the victim onto your working rope, limit the risk of a shock load (minimize the slack between you and the victim). With such significant loads, a small shock load can produce a very high impact force.

  1. Descend to the victim. Connect yourself to his dorsal attachment point.
  2. Install your handled rope clamp and your counterbalance system. Pull up with the right hand while pushing down with the left foot. The
    victim’s rope is thus unweighted.
  3. Disconnect the victim and transfer his weight to your system, then remove your counterbalance system. Add the required braking carabiner (e.g. FREINO) and descend with the victim.

 
This technique may be done with your personal equipment.

Reversible rescue kit :
The RIG can be used to make a rescue kit, and many solutions exist to create such a kit. The kit presented below consists of a haul system, an evacuation device, and a rope of sufficient length to lower the victim to the ground. Accompanied descent, pick-off technique using a haul system.
You arrive at the victim to transfer him onto your rope (green).

  1. Connect the haul system to the victim.
  2. Hoist the victim using the haul system to free him from his rope or lanyard.
  3. Descend with the victim to the ground using a braking carabiner.

Niveau expertEvacuating a person, device on the harness

Lowering a person (device on the harness) requires special attention. In this situation, the person controlling the descent cannot see the
person being lowered. It is necessary to have a directional point situated higher than the RIG to lower a person from the harness. The braking side of the rope must pass through a braking carabiner, the FREINO for example. Your feet are pressed against a solid surface, and you are anchored tightly and securely positioned. The rope must pass through a directional point. Beware of sharp edges and protect your rope. Gradually pull on the handle, while holding the braking side of the rope. Warning: if you are insecurely positioned, or if you pull the handle too quickly you risk being dragged along by the weight of the victim.

Niveau confirméLowering with device attached to an anchor (30 to 150 kg).

The RIG allows lowering with the device attached to an anchor, it is placed upside-down with a braking carabiner.
Lowering a person from an anchor requires special attention. In this situation, the person controlling the descent has no sensation of speed and can lower the person too fast. The landing can be rough. In a vertical position with the anchor plumb with the direction of descent, place the RIG above your elbows, but not above your head. Positioning the device in this way makes it easier to lower the person. Otherwise, managing the descent could be problematic. In effect, you would be poorly positioned to operate the handle and correctly hold the braking side of the rope.

Device on the anchor.
The braking side of the rope must pass through a braking carabiner. The braking carabiner serves to add friction. Hold the braking side of the rope and move the handle up (position D) to allow the rope to slide. Braking is regulated by varying the grip on the braking side of the rope. To stop, release the handle while holding the braking side of the rope.

PETZL

Evacuating a person (device on the anchor): pick-off using a haul system.
The rescue kit presented above can be used in the opposite sense.
This principle is used when the victim does not require special attention and can be lowered in free space.
You arrive at the victim. You install the kit on a nearby anchor.

  1. Connect the haul system to the victim.
  2. Hoist the victim using the haul system to free him from his rope or lanyard.
  3. Lower the victim to the ground.

Aid or hauling (pulley system)
The RIG can be used in a haul system. It serves as a progress capture device for hauling or freeing a person. It functions as a progress capture device without damaging the rope in case of overloading. If you want to stop the haul, you can lock the device in the work positioning mode. Warning: the RIG starts to slide at around 5-6 kN depending on the rope used (see test table). For greater efficiency, install the RIG at the head of the haul. This avoids efficiency loss due to rope stretch.

Niveau expert
Pre-installed system for descending to the ground
The RIG can be used to anchor a rope with a pre-installed rescue system from the ground. The rope may be installed from the ground using a throw-bag or ball attached to a thin cord. Install the RIG on the rope and attach it to the anchor. Put the handle into the work positioning mode and make a mule knot, locked with a connector. Warning: make sure there is enough rope to lower the victim. Always tie a knot at the end of the rope. For this system to work, you must leave in the bag a length of rope equal to the distance from the ground to the anchor, or expressed another way, the total system rope length must be three times the distance from the ground to the anchor.

BELAYING / PROTECTING

Niveau confirméBelaying the leader (100 kg)

We recommend using a dynamic rope (EN 892) for belaying the leader. Dynamic ropes are designed to hold and reduce the impact of a leader fall.
Fall factor 1 tests have shown (at the climber level) shock forces less than 6 kN with dynamic ropes, and greater than 6 kN with semi-static ropes (new ropes). When there is a risk of a fall factor 1 or greater fall, use a dynamic rope. Warning: When there is drag (significant rubbing friction on the belay rope) the actual fall factor can be greater than 1.

Device attached to the harness (position c)
Verify the rope is correctly installed before use. You belay your partner by holding the braking side of the rope in one hand, and the climber’s side in the other. To facilitate rope glide, focus more on pushing the braking side of the rope into the device rather than pulling the climber’s side of the rope. To stop a fall, firmly grip the braking side of the rope. To lower a climber, the manipulation of the device is similar to the description found under Descent.

Niveau débutantBelaying a second in a top-rope situation
Install the RIG on your harness (position c). Pull the braking side of the rope and push the climber’s side of the rope into the device.
Warning: never let go of the braking side of the rope. Never hold the two ends of the rope in the same hand above the device.

Niveau confirméBelaying one person with device attached to an anchor, 100 kg maximum load (without using a braking carabiner).
To belay a person from an anchor, the RIG is placed on the anchor upside-down. In this case a braking carabiner is not used to avoid excess friction that would interfere with the smoothness of the belay. To belay, hold the braking side of the rope in one hand and the second’s side in the other.
Take in slack regularly. To stop a fall, firmly grip the braking side of the rope. To lower a climber, the operation of the device is similar to the description found under Lowering from an anchor (use a braking carabiner).

Niveau expert
Belaying one person with device attached to an anchor, 100 to 150 kg maximum load

These techniques must only be executed by experienced users who are trained and practiced in using them with heavy loads. For loads exceeding 100 kg, the rope used (type, condition, diameter, etc.) has a significant effect on the RIG’s performance. Use gloves. Practice with your rope and be especially careful with new ropes. With such high loads, you must limit the risk of a fall. With such masses, even a small shock load generates a lot of energy. This can cause significant rope slippage in the device.
Take up rope regularly, keep a firm grip on the braking side of the rope. Do not allow slack in the rope.
No shock loading is allowed with a heavy load.

See Test 3

CLIMBING / PROGRESSING

Niveau débutantOccasional rope climbing

The RIG can be used for short rope ascents. If you have to do long rope climbs, use more efficient techniques (e.g. with ASCENSION and CROLL rope clamps).

Device attached to the harness (position c)
For greater efficiency, take up slack as you stand up using the rope clamp. Never allow slack between the rope clamp and the RIG.

Solution 1
Take up slack by pulling up.

PETZL
 

Solution 2
To reduce fatigue when you have a heavy bag, you can redirect the rope at the rope clamp. It is important to have the redirect point high enough to obtain a good step distance. This second solution is less efficient because the step distance is limited.

SUPPLEMENTARY INFORMATION

Tests
The following tests were done in labs; they were done on new ropes and devices, but it is impossible to recreate every scenario. Warning: we did not test every rope on the market; the results of these tests could be different with other types of rope. The test values are only indicative, so you have an order of magnitude of effort involved in such situations. Values recorded during tests with new PETZL ropes, certified to current European standards (EN 1891, EN 892). Certain tests were also done on new static ropes of different brands.

1. DYNAMIC TEST
Test
conditions

  • Rope length: 2m
  • Mass: 100kg
  • Fall factor: 1

The values given are averages; they vary depending on the rope models used.

PETZL

 
2. STATIC TEST
These tests were done using a slow pull.

PETZL

 
3. Belaying one person with device attached to an anchor, 150 kg maximum load
Extreme use case:
Fall factor 0.3 tests were done with a rigid 150 kg mass, falling 1 m onto 3 m of rope. The mass could be lowered after the test.
The energy in play is:
E = 150*9.81*1 = 1471 Joules.
This test represents a case of extreme usage for the RIG.

Also, the test condition were demanding:

  • On new ropes.
  • With the 150 kg rigid mass, direct.

In reality, the conditions are often more favorable because there are more rub points. The load is rarely transmitted directly; there are usually directional or rub points between the load and the anchor. The shock forces obtained in these falls are all between 6 and 7 kN, thanks to the slippage of the rope in the device (on semi-static ropes). These results are slightly higher on static ropes (for example NFPA light use certified
ropes): from 0.5 kN to 1 kN. The slippage in the brake hand is more than 100 cm.
These tests showed the importance of limiting slack in the rope and of ALWAYS keeping a firm grip on the braking side of the rope.
Holding the braking side of the rope allows rope slippage in the device to be minimized.
