to the right. If, instead, the operator is standing in front of Skylifter, the functions can be reversed. To reverse
functions, push button (8) forward.
Once the functions are reversed, Skylifter will again move the load to the right when the operator activates the
key/joystick to the right.
7.5 - Positioning/adjusting the vacuum yoke
1.
First rotate the vacuum yoke to the most appropriate position, depending on whether you want to
rotate the load during manoeuvring. Note that the rotation movement on Skylifter is limited.
The load must always be positioned so that the centre of gravity of the load is centred on the machine.
2.
Depending on the shape and dimensions of the load, the traverses must be positioned as far from
each other as possible. The same applies to 4 x suction pads: they should be positioned as far from
each other as possible.
A large distance between the suction pads ensures that the lift is as safe, balanced and stable lifting as
possible and minimises sensitivity, e.g. to gusts of wind.
The suction pads must be positioned at a distance of min. 25 mm from frames and edges.
3.
Check that each suction pad has both a red and a blue hose. If this is not the case, replace the suction
pads before attaching the load. Tighten the 6 finger screws manually.
Skylifter is now ready to attach the load using vacuum.
7.6 - Attaching the load
1.
Using the remote control unit, move the vacuum yoke slowly until it just touches the load. Correct the
position of the yoke until all 4 suction pads press lightly against the load. It will often be easier and
faster to tip the load towards the suction pads.
2.
To start both vacuum systems, press one of the buttons on the remote control unit marked with a red
circle. The load is now firmly attached to the suction pads.
NB: Now check the load! See instructions at the end of this section.
