(2) Insert secondary wire rope at (D), on T-series into
rope guiding device (E), and push through until it is
tensioned (Fig. 46).
(3) Above ground level fix a tensioning weight
(s1) of approx. 25 lbs. (10 kgs) to the low-
er end of the secondary wire rope (Fig. 46).
This weight will help to pull the secondary wire rope
through the BS/BSO secondary brake and avoid slack
wire rope above the hoist, which could be dangerous
in the event of fall.
(4) Take precautions to make sure tensioning weight
(s1) will not damage property or create a hazard
by swinging freely.
A4.3.3 Primary Wire Rope End
After primary wire rope reeving through the hoist,
be sure to loop and clamp the free end of the wire rope
to prevent the rope from inadvertently unreeving through
the hoist.
Always tie this loop, using a
fi
st grip clamp, when the
platform is at ground level (Fig. 47).
