• Measure as indicated (Fig. 7).
Do not expose the wire rope to temperatures
exceeding 100°C or to aggression by
mechanical or chemical agents.
At one end, the wire rope of the altotir™ winch
is equipped with a hook with safety latch
mounted on a wire rope loop equipped with
a thimble and a swaged sleeve. At this end,
it is also equipped with a limit stop located
between two specific sleeves. The other end
is fastened to the drum by a wedge socket
system (Fig. 14).
Check regularly that there are no signs of
damage where the wire rope is fastened to the
drum and to the lifting hook.
If any damage is observed, immediately
replace the complete wire rope.
6 Additional accessories
Optionally, Tractel
®
can also supply:
• A jib crane for mounting on scaffolding
(Fig. 8).
• An adjustable limit stop (Fig. 9).
6.1 Jib crane for scaffolding
This jib crane is particularly suited for use of
the altotir™ winch with tubular scaffolding of
diameter 49 mm.
The jib crane is secured to a vertical tube
of the scaffolding and the altotir™ winch is
anchored to the anchoring tube (Fig. 8,
item 5).
The scaffolding beam is shown in Figure 8.
The
scaffolding beam is fitted with
end-of-run stops in movement or rotation:
- one end-of-run stop is held by a bolt (Fig. 8,
item 6) located at the end of the anchor
tube, preventing the altotir™ apparatus
from sliding.
- 3 rotational angle end-of-run stops: one
placed in the central position indicated on
the scaffolding beam and in line with the
axis of the scaffolding tube and 2 angle
positions at +/- 100°from either side of the
central position. Rotational locking is carried
out by inserting the angle locking bar
(Fig. 10a, item 11) into the end-of-run stop
(Fig. 10a, item 10). In the unlocked position
the locking bar (Fig. 10b, item 11) is stored
in the nut (Fig. 10b, item 9). TRACTEL
®
recommends locking the scaffolding beam
in the event of long term non-use.

7 Setup, installation
7.1 General checks before installation
These checks are applicable to all the winch
utilization configurations described in this
manual.
7.1.1 Host structure checks
• The mechanical strength of the host
structure to which the altotir™ winch will
be anchored, and the strength of the
pulleys, must be compatible with the
WLL of the winch, with its own weight
added.
7.1.2 Environment checks
Before installing, check that:
• The electrical power source is compatible
with the altotir™ winch (230 V / 50 Hz
single phase); refer to the nameplate and
technical data table for the altotir™ winch.
