the recommendations of the lifting system
installation manual and this manual, in particular,
as concerns the distance between wire ropes (f).
EN
DANGER: The safety wire ropes are
special wire ropes. Use of any wire rope other
than those recommended by Tractel can result in
a serious malfunction when the fall arrest system
is used.
Make sure that the wire rope lengths are
compliant with the recommendations of the
lifting system installation manual.
Regularly check the condition of the safety wire
rope. In particular, check that:
• the wear of the wire rope is < 10% of its
nominal diameter Øc (fig. 20),
• the wire rope does not show any deformation
or damage as detailed in the manual for the
lifting device.
IMPORTANT: Check that the safety wire
rope is always lightly greased. Only multiple
purpose off-the-shelf greases should be used.
Do not use lubricants containing molybdenum
disulfide or graphite additives.
5.3) Assembly and installation of wire rope in fall
arrest device
– place the suspended platform directly in line
with the suspension points,
– secure the lifting and safety wire ropes. The
safety wire rope must be suspended freely
next to the lifting wire rope,
– unlock the fall arrest device by raising the lever
(item 1, fig. 17) in the direction indicated by
the arrow,
– place the lifting wire rope (item 1, fig. 18)
between the detection roller (item 2, fig. 18)
and the wire rope guide (item 3, fig. 18),
– insert the lifting wire rope in the hoist as
instructed in the installation manual for the
hoist installed on the suspended platform,
– using the hoist, raise the suspended platform
by 0.1 to 0.2 m. The lifting wire rope should be
tensioned and the fall arrest device should be
in the unlocked position,
– manually insert the safety wire rope in hole
A (fig. 1) of the fall arrest device, then have
it come out through hole B (fig. 1). Pull on
8
the free end of the safety wire rope until it is
tensioned,
– check that the distance (f) complies with the
value indicated in table 5 for the fall arrest
device used. If this is not the case, correct the
installation to ensure the distance required (f).
IMPORTANT: The wire rope coming out of
the fall arrest device must be free to move.
– Ballast the safety wire rope (item 1, fig. 19)
by fastening, at 0.2 m of the ground, a ballast
weight of:
• 9.5 kg for BSA15 and BSA20,
• 2 x 9.5 kg for BSA35.
Optionally,
the
ballast
counterweight of 9.5 kg; ref.021488) can be
supplied on order by Tractel.
6. Utilisation
NOTE: Protect the fall arrest devices
against soiling. Take the necessary measures to
prevent foreign matter from getting into the unit
with the safety wire rope. This recommendation
applies in particular in those cases where
concrete may be projected or synthetic resins
sprayed, or others.
Deposits of this kind can result in malfunctions
representing a safety hazard for the operators.
Utilisation of Blocstop™ BSA fall arrest device:
Once in place, the fall arrest devices do not
require any operator action.
These devices operate automatically for up and
down movements.
Once you have completed the necessary checks
as detailed in §5, you can proceed to use the
system.
IMPORTANT: When lifting, continuously
check that the safety wire rope slides freely in the
fall arrest device. If this is not the case, you must
mandatorily open the jaws. By tensioning the
lifting wire rope, the jaws will open automatically.
If the jaws do not open automatically, check that
the ballast weight is correctly positioned. If this
is not the case, set the suspended platform on
the ground, remove the fall arrest device and
weight
