Safety wire rope tensioner system
The safety wire shall be fastened on the bottom with
counterweights (tension of 22 kg) or other system which
will produce a tension force of at least 400 N. Some of
the systems that could be used are shown in the
following images.
If the push spring is installed follow this procedure:
1) Feed the safety wire rope through the bottom platform
hole.
2) Ascend the service lift 50 cm.
3) Activate the fall arrest device.
4) Perform manual descent so that the weight of the
service lift is transmitted to the safety wire rope.
5) Compress the spring to 40 mm and fix with cable ties.
6) Feed the safety wire rope through the compressed
spring.
7) Pull the safety wire rope downwards by hand as much
as possible.
8) Place and fasten the wire rope grip.
9) Put the cable ties so that the spring decompresses to
55 mm.
If the counterweights are installed follow this procedure:
1) Mount two 11 kg counterweights on the safety wire
rope.
2) Secure them by using 2 wire clips.
To install other alternative system, please contact Avanti.

must be coiled and fastened with at least 3 strips. The
counterweight and the excess of wire rope shall be able
to rotate freely.
