7.2.3 Checks after installation
7.2.3.1 Checks without load
After completing the installation, check that:
• The winch is correctly connected
electrically.
• The electric power cable and the control
cable are not subject to any pulling or to
any risk of grabbing when the jib crane is
rotated along its travel range.
• The winch control unit is within arm's
reach of the operator over the jib crane's
entire travel range.
• The operator can manually pivot the jib
crane.
• The jib crane pivots with no sticking
points or grabbing over the entire
working travel.
• No interference is observed between the
wire rope, equipped with its hook and its
limit stop, and the environment over the
entire load lifting length.
• There remains at least 2 wire rope coils
on the drum when the wire rope is fully
extended to the low limit stop.
7.2.3.2 Checks with load
• Secure the maximum working load to the
lifting hook (Fig. 1, item 2).
• When the load lifts off the ground, check
that:
- The scaffolding remains stable.
If
not,
immediately
movement, remove the load, and take
the necessary steps to stabilize the
scaffolding.
- There is no deformation, cracks or
rupture on the scaffolding tube (Fig.10,
item
24)
or
in
the
environment.
If any problem is observed, immediately
stop the up movement and dismantle
the altotir™ winch.
- There is no slippage between the pivots
(Fig. 8, items 3 and 4) and the scaffol -
ding tube (Fig. 10, item 24).
If slippage is observed, immediately stop
the up movement, remove the load, and
re-tighten the nuts (Fig. 8, item 1) using
the 19 mm open end wrench.
- No interference is observed between the
load and the environment over the entire
load lifting height, using the control unit.
- The jib crane with load in the up position
pivots with no excess effort required on
the part of the operator.
- When pivoting the jib crane along its
travel range, no rotation slippage occurs
between the pivots (Fig. 8, items 3 and
4) and the scaffolding tube (Fig. 10,
item 24)
If slippage is observed, immediately stop
the jib crane rotation, lower the load to
the ground, reposition the pivot and
properly tighten them on the scaffolding
tube.
- No deformation on the ground or on the
working platform is observed when the
load is set down.
7.3 Installation on frame
This installation configuration is used when
the lost height of the winch is not compatible
with the lifting height (Fig. 11). For this
installation, the installer must have:
• 1 altotir™ winch, standard delivery,
• 1 adjustable limit stop (Fig. 9),
• 2 idler pulleys,
• 1 tubular
diameter of 49 to 50 mm (Fig. 11) and
stop
the
up
whose mechanical strength has been
verified by a qualified technician
For this installation configuration, the winch
is turned over; the mounting clamps, for
mounting on tube, are under the winch and
the lifting wire rope comes out toward the top
immediate
in the direction of the pulley located directly
in line with the winch.
