Precautions during hauling

- The ASAP must be installed on the haul strand to provide a backup should either rope strand fail.

- Beware of rubbing between the moving haul strand and the anchor strand, which is stationary. To the extent possible, the two strands of rope should follow different paths.

WARNING: the weak point of this system is the risk of a rock severing the rope very close to the I'D or ASAP.

In this worst case scenario, the device should lock onto the rope very close to its severed end, which presents a risk of releasing the load.

If there is a risk of rockfall, it is recommended to use another technique or to use a second safety rope.
