Changeovers

Changing from ascent to descent

1. Place the back-up device high up on the safety rope.
2. Attach the descender device onto the working rope, directly below the chest ascender.
3. Take in any slack rope through the descender until approximately 50 mm remains between the descender and the chest ascender.
4. Lock off the descender.
5. Move the back-up device to a position just above waist height.
6. Position the handled ascender at head height so that when standing in the foot loop, weight will just be taken from the chest ascender.
7. Stand up in the foot loop whilst disengaging the chest ascender, and then sit back onto the descender, which will then become weighted.
8. Remove the handled ascender and foot loop from the working rope and begin to descend.

Changing from descent to ascent

1. Stop the descent. Lock off the descender and position the back-up device high up on the safety rope.
2. Attach the handled ascender to the working rope above the descender, leaving room between the two to allow attachment of the chest ascender.
3. In one movement: stand up in the foot loop, locate the chest ascender onto the working rope, close the cam, and sit back onto the chest ascender.
4. Remove the descender from the working rope and begin to ascend.
