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.
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 has more than
10 broken wires along a length of 200mm
should be eliminated. Standard ISO 4309
(Lifting devices for suspended loads – Wire
ropes – Servicing, maintenance, installation,
inspection and removal).
