WARNING
Risk of injury due to obstruction of the load rope!
Due to poor all-round visibility, the climber may inadvertently tie in
the load rope with his safety rope.

Both as a climber and as a ground man, make sure that the load
rope is not obstructed by safety ropes.

Make sure that the rope runs vertically into the bollard from above.
Communication
Communication between the rigging partners is safety relevant.
Depending on the point of view of the ground man or the climber, the
overview of the course of ropes, cuts, inclinations of tree parts as well
as the estimation of the weight of the tree parts can be very different.
Helmet radio and/or predetermined hand signals facilitate communi-
cation during work.
›
Check the procedure of your rigging partner according to the
four
eyes principle
.
›
In the event of unclear and dangerous situations, interrupt work at
short notice with a previously defined
stop signal
.
Working in a changing position (climber/ground man) allows
a better understanding of the work and safety aspects of the
respective work area.
