How to install a top-rope
Installing a top-rope is one of the basic techniques first learned in rock climbing. Even if it eventually becomes routine, it is important to keep in mind that 30 to 40 m above the ground an error can quickly have serious consequences. So remain focused when climbing and belaying!
- 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.
Technique 1: Lowering on a carabiner
- Climber remains tied in during all maneuvers.
- Climber is lowered on a locking carabiner.
- Make sure that the carabiner is loaded on its major axis.
- Working the route during descent is not recommended.
Technique 2: Lowering on the tie-in knot
- A single strand is passed through the quick link (useful for narrow quick links).
- Allows working the route during descent.
- Climber tethered with manufactured dynamic rope lanyard
- Climber not tied in during maneuver.
- Climber must tie in again.
With either technique, it is essential that the belayer continues to belay the climber throughout the maneuver, never letting go of the brake side of the rope.
