Phase 3: Installing the adjustable limit stop
IMPORTANT:
The adjustable limit
stop must be installed on the section of lifting
wire rope located between the altotir™ winch
and the idler pulley, winch side (Fig. 11,
item 4).
•
Install the adjustable limit stop as
detailed in the procedure given in
section. 14.3
• Position the adjustable limit stop to
ensure that:
• When the lifting hook is at the low limit,
the adjustable limit stop (Fig. 11, item 6)
does not interfere with the idler pulley,
winch side (Fig. 11, item 4).
• When the adjustable limit stop is in
contact with the limit stop lever (Fig. 11,
item 9), the limit stop (Fig. 11, item 10)
does not interfere with the idler pulley,
load side (Fig. 11, item 5).
• Manually check that the adjustable limit
stop is locked on the wire rope.
7.3.3 Checks after installation
7.3.3.1 Checks without load
Check that:
• There is no interference between the
adjustable limit stop (Fig. 11, item 6) and
the idler pulley, winch side (Fig.11,
item 4) when the lifting hook is at the low
limit.
• There is no interference between the
limit stop (Fig. 11, item 10) and the idler
pulley, load side (Fig. 11, item 5) when
the limit stop lever (Fig. 11, item 9) is
actuated by the adjustable limit stop
(Fig. 11, item 6).
• No interference is observed between the
wire rope, equipped with its hook and
limit stop, and the environment along the
entire load lifting height.
• No interference is observed between
the wire rope equipped with its
adjustable limit stop, and the environ -
ment along the entire load lifting height.
• The winch stops, on an up-movement
cycle, when the adjustable limit stop
(Fig. 11, item 6) comes into contact with
the limit stop lever (Fig. 11, item 9).
If this is not the case, immediately stop the
up-movement and have the limit stop lever
checked by a qualified technician.
• There are at least two coils of wire rope
remaining in the warping drum at the low
unwinding limit.
• No slack wire rope is observed while the
lifting hook is being lowered, in particular
between the 2 idler pulleys. If any slack
wire rope is observed, fit a weight on the
lifting hook to ensure that the wire rope
remains tensioned (2 kg max.).
7.3.3.2 Checks with load
• Fasten the maximum working load to the
lifting hook (Fig. 1, item 2).
• When the load lifts off the ground, check
that:
- There are no signs of deformation,
cracks or rupture on the anchoring tube
(Fig. 11, item 2) or in the immediate
environment.
If any problem is observed, immediately
stop the up-movement, remove the
weight on the ground, and have the
instal lation checked by a qualified
technician.
- There are no signs of deformation,
cracks or rupture next to the idler pulley
rigging point (Fig. 11, items 4 and 5) or in
the immediate environment.
If any problem is observed, immediately
stop the up-movement, set the load on
the ground and have the idler pulley
rigging point checked by a qualified
technician.
- No interference is observed between the
load and the environment along the
entire load lifting height, by acting on the
control unit.
- No deformation on the ground or on the
working platform is observed when the
load is set down.
