Belaying with a rope as a complement to energy-absorbing lanyards
- Read the technical notice before viewing the following techniques.
- It is important to fully understand the information provided in the technical notice before using this complementary information
- Mastering these techniques requires training.
- Consult a professional before attempting to perform these techniques on your own.
Thanks to the consistent presence of solid equipment, the via ferrata allows more people to easily access vertical terrain. However, the risks present in vertical activities, and particularly the risk of falling, remain. The use of energy-absorbing lanyards allows fall arrest and limits impact force on the user.
The fall is made up of two phases:
- sliding along the cable, with the lanyard inactive
- the impact on the first anchor reached, activating the energy absorber
The fall has risks that the lanyard cannot prevent: the user can hit a bar, the rock, or other users.
Obstacle hit before the energy absorber is engaged
Obstacle hit after the energy absorber is engaged
Using a rope
Using a rope along with energy absorbers limits the length of the fall and its potential consequences.
Using a rope is strongly recommended in the following situations :
- difficult passages with elevated risk of falling
- situations where the user risks hitting an obstacle before the fall is arrested by the energy absorber
Using a rope is required in the following situations:
- progression with children or climbers weighing under 45 kg or over 100 kg
- old or poorly installed equipment in place (cable overly taut or anchors more than 3 m apart)
To use a rope, the party must get organized the same as for climbing, with a leader who knows how to manage belaying the seconds.
Belaying while moving is an option reserved for less steep and/or easier sections. Belaying from intermediate anchors is recommended for all tricky sections.
Simultaneous progression when traversing
The rope is passed through the pigtails while progressing. The two team members must always have at least one pigtail active between them.
Lanyards are essential for limiting the risk of a pendulum in case of a fall.
Alternating progression when descending
The beginner must always be below the leader and so gœs first when descending.
