Never remain under the load being lifted,
and never try to grip the load from below!
Remain at a safe distance!
Avoid shearing effects caused by bag squeezing when deflating.
Never stand in front of the load during operation, always place
yourself to the side of it, because the bag can be catapulted out
under unfavourable conditions.
3. Preparing the product for use
3.1 Preparations for operation
Remove the set of lifting bags from the transport and unpack the
packing bag. Make certain that the inflation device is ready for
operation. Make certain that there is sufficient air supply available.
Connect the inflation hoses on the one side to the lifting bags and
on the other side to the dual controller.
Only perfectly working and tested lifting bag
systems are to be used.
The person in charge of the operation is to decide on the method
and how it is to be applied from case to case within the field of his
responsibility as well as observance of the operating instructions
of the user.
3.2 Application instructions
Move the lifting bag to a suitable position so that at least 75% of
the supporting bag surface is under the load.
Normally at least two bags are used of the same type and size. Po-
sition each bag near to the end of the load. If necessary use lines
for drawing under the load or lower between loads which have to
be pressed apart.
Depending on the low operation pressure
of the lifting bags, the maximum pressure
point loading is only:
1,0 kg/cm² with lifting bags 1.0 bar
Due to low bearing pressure, under-support for ground fixture is
only necessary in exceptional cases.
The load to be lifted is to be secured
against slipping by suitable measures !
Before moving the lifting bag under the load it should be ensured
that the side wall material is positioned between the top and bot-
tom plates. Under no circumstances should the side wall material
be between the load and top or the load and bottom during the
lifting sequence. This can, under certain circumstances, cause da-
mage to the side wall of the bag.
