5.2 Lifting Loads
Switch on the vacuum generation.
Position the lifting device directly above the load. Do not pull to the sides.
Distribute load evenly.
Lower the lifting device onto the load. Ensure that all suction pads are in
contact with the load. On devices with switchable suction pads, deactivate any
suction pads which are not in contact with the load. Otherwise, it will not be
possible to generate a vacuum . Ensure that all suction pads in contact with the
load are activated.
Slide the sleeve of the manually actuated valve on the operator handle to the
position "Pick up load ". The suction pads grip the load.
Watch the pressure gauge. As soon as a vacuum pressure of -0.6 bar has
been reached you can lift the load. Never attempt to lift the load with a lower
vacuum since it will be dropped.
When lifting, ensure that only one piece of the items to be lifted is actually
lifted. Before lifting, carefully remove any other pieces sticking to the one you
want to lift with the aid of a screwdriver. Do not try to separate the items with
your hands, since this could result in injuries.
5.3 Lowering Loads
Lower the load to a safe and clear, level surface so the load cannot slip or tip
over.
Press the locking button on the manually actuated valve and slide the sleeve to
the position "Release load". The load is released.
5.4 Moving the
Lifting Device
with the
Chain Hoist
Move the chain hoist with the lifting device smoothly, since jerks could cause the
lifting device and the attached load to rotate or swing.
!! Accident hazard !!
5.5 Adjusting the
Load
Suspension
Devices with more than two suction pads have adjustable rails.
The adjusting of the rail is described in the section "Installation".
Adjustment for lifting a
flexible load
Danger
When lifting flexible loads with large dimensions with a lifting device with than two
rails, ensure that the load is distributed evenly between all suction pads. In other
words, all suction pads must be at about the same height when the load is picked
up (Figure 2). Suction pads which do not share the load will reduce the maximum
lifting capacity of the device.
