7.4.3.2 Checks with load
• Fasten the maximum working load to the
lifting hook (Fig. 1, item 2).
IMPORTANT: The load must be
secured to the wire rope by the hook.
The load must be secured by a sling of
appropriate capacity, dimensions and type
for the object to be handled. The winch wire
rope must not be used, under any
circumstances, as a sling by running it
around an object with the hook attached to
the wire rope (Figs. 17 and 18).
When the load lifts off the ground, check that:
• There are no signs of deformation,
cracks or rupture on the seating plane
next to the base tube (Fig. 12, item 2) or
in the immediate environment.
If any problem is observed, immediately
stop the up-movement, set the load on
the ground and have the installation
checked by a qualified technician.
• No interference is observed between the
load and the environment along the
entire lifting height, by acting on the
control unit.
• No deformation on the ground or on
the working platform is observed when
the load is set down.
• The winch does not move on its seating
plane.
The dimensional specifications of the
opening to be provided in the platform are
indicated in Figure 12.
7.5 Commissioning
General checks
Check that:
• The load to be lifted is less than or equal
to the WLL of the altotir™ winch.
• The lifting wire rope is in good condition.
• The safety systems are placed correctly.
• The working area is secured in com -
pliance with the applicable regulations.
Additional checks when using idler pulleys.
Check that:
• The rotation axis of the pulleys is
perpendicular to the wire rope plane.
• The adjustable limit stop is in place on
the wire rope.
8 Maneuvers
8.1 Preliminary conditions
Before performing any maneuvers with the
altotir™ winch, the operator must ensure
that:
- The lighting conditions are satisfactory
along the entire load lifting height.
- The wind speed is compatible with use
of the winch (< 50km/h).
- The climatic conditions are compatible
with the winch operating specifications
(section 4.4).
- The load to be lifted is an equipment
load and not a person.
8.2 Checks before use
Before using the altotir™ winch, the operator
must ensure that:
• The control unit does not show any
visible damage.
• The load to be lifted is less than or equal
to the WLL of the altotir™ winch.
• On the entire lifting height, there is no
risk of interference of the wire rope or of
the limit stops with an obstacle.
• The wire rope is in good condition along
its entire length.
• The control and power cables are not
damaged.
• The safety systems operate correctly.
• The work area is secured in compliance
with applicable regulations.
Additional checks according to installation
configuration:
If the winch is used on a jib crane, check that:
• The jib crane pivots freely along the
working travel range planned.
