3.2.2 Operating principle

Using the two control buttons on the control
unit (Fig. 1, item 21), the operator controls
lifting and lowering of the load secured to the
lifting hook (Fig. 1, item 2). To stop an up or
down movement, the operator simply
releases the control button used.
3.2.3 Characteristics of host structure
IMPORTANT: Before using the hoist,
the operator must make sure that the
scaffolding is sufficiently strong and stable to
handle the working load limit of the winch, to
which the weight of the unit and its
accessories must be added, in compliance
with applicable rules and regulations.
3.2.4 Complementary product
required (see Section 7)
When using the altotir™ winch on scaffolding,
a scaffolding jib crane (Fig.8) is required. The
altotir™ winch must be secured on the jib
crane tube (Fig. 10, item 11) by its mounting
clamps (Fig. 10, item 8).
The assembly formed by the altotir™ winch
and the jib crane must be secured to a
vertical tube of the scaffolding using clamps
and a pivot (Fig. 8, items 3 and 4).
3.3 Compliance with applicable
regulations and standards
The altotir™ winch satisfies the requirements
of machinery directive 98/37/CE and outdoor
directive 2000/14/CE.
4 Description

4.1 Description of functions

The altotir™ winch is formed by a frame and
a geared motor assembly coupled to the wire
rope warping drum.
The frame ensures the following functions:
• Enables setting the winch on the ground in
a stable position on its base tube (Fig. 1,
item 12)
• Allows 2 persons to carry the winch by its
carrying handle (Fig. 1, item 11).
• Protects the assembly formed by the
geared motor and drum (Fig. 1, items 3, 4,
5) against projections and impacts when
installing and during use, transport and
storage of the unit.
• Ensures protection of the electrical unit
(Fig. 1, item 6) against projections, impacts
and weather when installing and during use,
transport and storage of the unit.
• Facilitates storage by its rectangular shape.
• Provides access to the electrical unit (Fig.
1, item 6) by an access plate covering the
electrical unit (Fig. 1, item 18).
• Ensures storage of the control unit (Fig. 1,
item 15) and the power connector (Fig. 1,
item 20) during transport and storage of the
unit.
• Enables securing the unit in its working
position by means of clamp fastening studs
(Fig.1, item 13) and clamp fastening cross-
members (Fig. 1, item 7).
• Enables use of the winch seated on the
ground (Fig. 12).
The geared motor ensures the following
functions:
• Lifting and lowering of a load by a single
phase electric motor (Fig. 1, item 4) driving
a reduction gear (Fig. 1, item 22), itself
driving a drum on which the wire rope winds
and unwinds.
• Enables maintaining the load in a stopped,
stationary position during an up or down
cycle by the spring-applied break.
