Performance of the ASAP with a 250 kg load, with the ASAP fixed to an anchor.

Test results for an exceptional situation: fall of a 250 kg mass, arrested by a belay system using the ASAP fixed to an anchor. This corresponds to a two-person rescue situation in which any fall must be carefully avoided.

Warnings

  • 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.

Tested situations

Installation with a redirect.

Note: with the ASAP and an attentive operator, is is easy to avoid having any slack in the system, which is recommended.

Installation without a redirect.

Conclusion and usage precautions

The short fall distance makes it possible to avoid exceeding the energy-absorption capacity of the ABSORBICA L57.

The ASAP may thus be used in this case.

The rope must be continuously and carefully managed to avoid any slack.

For a 250 kg load or two persons, use the ASAP only with an ABSORBICA L57 energy absorber.

Pay attention to the ASAP's direction of installation in this situation: do a test of the locking direction before each use.

The rope must pass through a redirect at the anchor.

Warning: for every installation, allow enough clearance for the ASAP to move during deployment of the energy absorber.

Results

Tests with OXAN at the redirect

ASAP fixed to the anchor with an ABSORBICA L57, on VECTOR 11 mm rope, 38 cm fall.
