The direction of movement of the fall protection runner must be heeded
and is specified by an arrow on the runner. This arrow must always point
upwards. A safety mechanism prevents the fall protection runner being
attached the wrong way round. In this case the housing of the runner
does not close and it cannot be used.
The carabiner hook is equipped with a threefold-secured opening mecha-
nism. To open the carabiner hook the fastening sleeve must be pushed
as far as it can go in the direction of the fall arrest rail, then rotated as
far as possible to the left, and then pushed back as far as possible in the
direction of the fall arrest rail. After the carabiner hook has been hooked
up, care must be taken that the self-locking mechanism on the front at-
tachment point of the safety harness is closed.
A horizontal tensile force is applied to the fall protection runner by the
user leaning back gently and smoothly. This opens the braking mecha-
nism and the fall protection runner moves freely so that the user can
climb up. If the user stops when climbing and relieves the system, the
spring-loaded braking mechanism closes and the fall protection runner
similarly comes to a halt.
Climbing down takes place according to the same principle.
Arms are relieved when climbing up and down. When climbing the user
must always grp hold of least 3 points (three-point climbing technique).
The fall protection runner has three arrest functions which are independ-
ent from each other. Each reacts to different triggers caused by a risk to
the user, and brings the fall protection runner to a halt. If the horizontal
or speed-related arrest function is primarily activated, the vertical arrest
function is always triggered secondarily as back-up!
Vertical arrest function:
In the event of a fall, the user attached by the carabiner on the safety
harness moves the braking tappet in the fall arrest runner. As a result
the fall protection runner seizes like pincers within a few millimetres on
the rail. The intervention and stopping of the runner are delayed and do
not take place abruptly, as in the case for example with fall protection
systems whose runners have ribbing or rungs at specific intervals as ar-
rester. This reduces the load impacting on the falling person. Once the
fall protection runner has been released and following the associated
“pincer opening”, this safety function returns immediately to standby
position again.
