4.6 Control components

The winch is operated by pressing either the
"Up" or "Down" button on the control unit
(Fig. 1, item 16); The control unit must
always be held in a vertical position by which
it hangs from its control cable. Never place
the control unit in the upside-down position
(control cable down) as this could result in
erroneous maneuvers.
When the "Up" or "Down" button is released,
the movement stops.
GB
NOTE: "Up" and "Down" is indica -
ted on the corresponding control button by
an arrow pointing in the direction of
movement controlled, with the control unit
held upright and the control cable leading
upward (Fig. 1, item 16).

4.7 Safety devices

The altotir™ winch has the following safety
devices:
• Spring-applied brake (Fig.1, item 5).
• Red emergency stop button on control unit
(Fig. 1, item 16).
• Mechanical interlocking, inhibiting simulta -
neous action of the Up and Down controls
(integrated in control unit).
• Limit stop lever on winch (Fig. 1, item 9)
which functions with the limit stop (Fig. 1,
item 10), which can either be fixed or
adjustable, to meet the installation needs.
• Safety latch on hook (Fig. 4, item 2 ).
• Electrical protection of control unit: class 2.
The emergency stop is obtained by pressing
the red emergency stop button (Fig. 1,
item 16). In order to restart the winch after an
emergency stop, the emergency stop button
must be released by turning it in the direction
of the arrows marked on the button, after you
have made sure that the emergency
condition has been eliminated.
The hook with safety latch is shown in
figure 4.
Composition :
1) Lifting hook
2) Safety latch
NOTE: The 230V single phase
motor is protected against overheating by a
temperature sensor in the winding. The
sensor inhibits operation and interrupts the
control circuit when the temperature in the
winding is not below the trigger threshold
value.

5 Wire rope

The lifting wire rope, equipped, is shown in
figure 5.
Composition :
1) Lifting wire rope
2) High locking sleeve for limit stop
3) Limit stop
4) Low locking sleeve for limit stop
5) Loop with thimble
6) Lifting hook
IMPORTANT: To ensure safe use of
the altotir™ winch, only the altotir™ wire
rope, specially designed for this winch,
should be used.
DANGER: 1. Use of the winch with
a damaged wire rope or with a wire rope
which is not appropriate for the winch
represents a major risk of accident and
failure. The wire rope must be checked
regularly on an on-going basis to ensure that
it is in good condition. Should the wire rope
show any signs of damage, such as
deformation, bending, broken wires (Fig. 6),
it should be immediately replaced. Any wire
rope for which the nominal diameter has
been reduced, due to wear, by 10%, or which
