Position in relation to the anchor with the ZILLON

 

Warning: even if you are secured by a primary system such as a ZIGZAG, follow these instructions when using your ZILLON.

Our tests show that in a pendulum on the ZIGZAG rope, there is a free-fall phase that exceeds the 40 cm maximum fall authorized for the ZILLON.

 

At the end of a branch, it is common to not have another branch above for installing the lanyard.

In this case, the arborist has no choice other than to install his lanyard at foot level on the branch he is working on. Thus, it is important to keep the lanyard taut and oriented in a direction that prevents a pendulum on the primary belay system.
