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.
The inverted assembly configuration on
structure is shown in figure 11.
Composition:
1) Wire rope
2) Anchoring tube
3) Host structure
4) Idler pulley, winch side
5) Idler pulley, load side
6) Adjustable limit stop
9) Limit stop lever
10) Limit stop
7.4 Installation bearing on base tube
This installation configuration is used when the
installer does not have an anchoring point for
the idler pulley under the structure. For this
installation, the installer must have a standard
altotir™ winch.
7.4.1 Checks before installation
7.4.1.1 Host structure checks
IMPORTANT:
Before installing, you must check that:
• The seating plane for the altotir™ winch
(Fig.12, item 2), is sufficiently strong.
• The seating plane for the altotir™ winch
is horizontal and smooth.
• The wire rope opening under the altotir™
winch observes the dimensions require -
ments specified in Figure 12.
• The winch is properly wedged on the
seating plane to avoid any movements of
the winch when operating.
7.4.1.2 Environment checks
Before installing, perform the general checks
detailed in section 7.1.2.
7.4.1.3 Winch checks
Before installing, perform the general checks
detailed in section 7.1.3.
7.4.2 Installing the altotir™ winch
Proceed as detailed below for installation of
the altotir™ winch on the base tube.
No special tools are required.
• Run the wire rope, equipped with hook and
limit stop, through the opening provided
for passage of the wire rope.
• Position the altotir™ winch next to
the wire rope opening, observing the
positioning recommendations specified
in Figure 12.
• Wedge the winch so that it does not move
when operating.
7.4.3 Checks after installation
7.4.3.1 Checks with no load
After installing, check that:
• No interference is observed between the
wire rope, equipped with its hook and
limit stop, and the environment along the
entire load lifting height.
• The winch stops during the up-movement
when the limit stop (Fig. 12, item 10)
comes into contact with the limit stop
lever (Fig. 12, 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 on the warping drum at the
low unwinding limit.
