Suspension Cable System
ADVANTAGES OF THE CABLE SUSPENSION SYSTEM
• Big bearing capacity - 5:1 system load ratio
• Instead of threaded rods – no cutting,
fi
ling or fastening nuts any more
• Quickness – installation time cut by 80%
• Safe – light-weight, installation and
fi
tting on the spot
• Time & money saving- no auxiliary brackets required

**) – Do the task if there are at least three suspensions, as otherwise the suspended object may fall down and cause injury or death. Manufacturer renounces any responsibility if the condition is not satis
fi
ed.
1. Should an installation be exposed to high level of humidity or acidity,
an appropriate material has to be selected for the suspension system. Locally
prevalent conditions should be consulted before making choice of such material
and doing the installation itself.
2. With the installation completed, the suspension has to be checked at least
once a year.
1 Enlargement/diminishing of the bracket lug
(use the included tool to press on the safety pin
in the self-clamping clip to release the cable therein,
the lug size thus becomes adjustable **)
2 Suspension’s self-clamping clip
(use the included tool to press on the safety pin
in the self-clamping clip to release the cable therein,
length of suspension thus becomes adjustable **)
3 Length of suspension
(basic length is 2 or 4 m, taken from the cable end to the
snap hook lug)
4 Snap hook with wire safety pin
(11 mm in clear diameter). The snap hook is snapped into
the suspension system lug
(the wire safety pin will not allow spontaneous release
under vibrations, if any)
