altotir™ winch and installation
on scaffolding
The altotir™ winch, equipped with the jib
crane, is shown in figure 10.
Composition:
7) Fastening crossmembers
8) Tube mounting clamps
11) Anchoring tube
13) Clamp fastening studs
14) Clamp fastening nut
GB
24) Cylindrical scaffolding tube.
Proceed as follows when securing the
altotir™ winch on a jib crane:
Tools required:
• 1 open end wrench, 17 mm
• 1 open end wrench, 19 mm
The installation procedure
3 phases:
Phase 1: Assembling the altotir™ winch and
the jib crane (Fig. 10).
• Position the anchoring tube (Fig. 10,
item 11) of the jib crane in the slots
provided for this purpose on the
fastening crossmember (Fig. 10 , item 7).
• Fit the mounting clamps (Fig. 10, item 8)
on the studs (Fig. 10, item 13).
• Manually screw on the 4 clamp fastening
nuts (Fig. 10, item 14) uniformly.
• Using the 17mm open end wrench,
moderately tighten the 4 nuts.
• Check that the mounting clamps (Fig. 10,
item 8 ) and the fastening crossmember
(Fig. 10, item7) are in contact with the
anchoring tube of the jib crane (Fig. 10,
item 11).
• Check that the jib crane is rigidly secured
to the altotir™ winch.
Phase 2: Installing the jib crane pivot on the
scaffolding tube.
• Couple the male pivot clamps (Fig. 8,
item 3) with the male pivots (Fig. 8,
item 4) using the screws, nuts and
washers (Fig. 8, items 7, 1, 2).
• Place the assembly formed by the male
pivot on the scaffolding tube (Fig. 10,
item 24); if necessary, slightly loosen the
clamp mounting
installation.
• Close the male pivot clamp (Fig. 8,
item 3) on the scaffolding tube then
manually tighten the mounting nuts (Fig.
8, item 1) symmetrically on each pivot.
• Before you lock the mounting nuts using
the 19 mm open end wrench, check that
the distance between pivots is 320 +/-
1 mm (Figure 2b) and that the pivots are
positioned in line with each other.
• Firmly lock the pivot clamp fastening nuts
using the 19 mm open end wrench.

Phase 3: Installing the altotir™ winch equip -
ped with the jib crane on the
scaffolding
• Position the jib crane equipped with the
altotir™ winch on the male pivots as
shown in figure 8.
• Using the 19 mm open end wrench,
horizontally adjust the anchoring tube
(Fig. 8, item 11) by tightening or
loosening the adjustment locknut (Fig. 8,
item 10). Once the jib crane tube is
horizontal, lock the pivot by tightening
the locknut (Fig. 8, item 10 ).
• Check that the assembly formed by the
altotir™ winch and the jib crane pivots
with no sticking points or grabbing over
the pivot working range.
• Connect the altotir™ winch to the
electrical power supply.
