5. Installation
As specied in §2, the BS fall arrest device
can be used on material’s lifting and pulling
installations.
5.1. Installation of fall arrest devices
IMPORTANT: The fall arrest device
mounting system must provide a tensile strength
of at least four times the nominal capacity of
the Blocstop™ BS fall arrest device. This is
indispensable to ensure the mechanical strength
of the installation should a fall occur.
Before you begin to install the fall arrest device,
check that the unit is in good visible condition
and, in particular that:
– there are no signs of impact or deformation on
the fall arrest device,
– the stirrup (item d, g. 1) swivels freely on its
swivel pin,
– the marking on the device is legible and
compliant with the information in the “markings”
section for the unit,
– the holes (items a and f, g. 1) are neither
soiled or obstructed.
“NOTE”: The fall arrest device is supplied
with a shackle (item e, g. 1) optionally. Any other
shackle having the following characteristics can
be used:
– BS 15 and BS20: shackle (min. opening A = 38
mm, g. 26, with Ø12 pin and cotter pin (item h,
g. 1) with working load limit of 1.6 t.
– BS35: shackle (min. opening A = 55 mm,
g. 33, equipped with Ø22 pin and a cotter pin
(item h, g. 1) with working load limit of 3.2 t.
5.2. Preparation of wire ropes
See §5.4.
5.3. Assembly and installation of lifting
wire rope in fall arrest device for a
load lifting or pulling installation
(g. 21)
”NOTE”: The fall arrest device can
be adapted to any lifting or pulling device
implementing a feed-through wire rope
(TIRFOR
®
manual hoist or TIRAK™ electric
hoist) equipped with a TIRFOR
®
or TIRAK™
wire rope.
Fig. 21 illustrates installation of the fall arrest
device with a TIRFOR
®
hoist implementing
a feed-through wire rope; the installation
procedure is as follows:
– secure the fall arrest device (item 3, g. 21) by
its shackle (item 6, g. 21) to the anchor point
(item 8, g. 21) using a sling (item 1, g. 21).
IMPORTANT: make sure that the fall arrest
device is always properly aligned with the lifting
or pulling wire rope and that the slack in the sling
does not exceed 5 cm to prevent any excessive
jolting if a lifting or pulling system failure occurs.
– secure the TIRFOR
®
(item 2, g. 21) to an
anchor point (item 10, g. 21),
– release the TIRFOR
®
to allow insertion of the
wire rope (see TIRFOR
®
manual),
