and ensure any claims made within the framework of the Vetter guarantee.
Only a person who has been instructed in the use of Vetter Lifting Bags,
using the manufacturer operating manual and the instructions from the
user, is to be given the operation task.
The disposal of discarded lifting bags is to be carried out according to
disposal regulations valid for the region.
The operating instructions given here are to be regarded as part of the
product and are to be kept for the complete life duration of the product.
In case the product should be passed on to a successive user then the
operating instructions must also be included.

2.3 Application area
Due to the high pressure point load, it is frequently not possible to use
winches or hydraulic lifting gear when dealing with heavy, unstable loads.
In such cases the advantages of Vetter lifting bags become very much apparent:
9 Very light
9 Low pressure point loading
9 Very at in design
9 Can be used in any position
As already known, air distributes itself evenly on all sides. The ideal shape of
a pressure container is spherical. With exible pressure containers, such as
the lifting bag, the top and bottom as well as sides bulge.
With lifting bags this bulging, especially of the top and bottom, could damage the bag when pressed against sharp objects and the bag may become cut, punctured or abraded.
Danger of damage to the pressurized walls of the
bag.

2.4 The VETTER construction
Bags which have a cylinder shape cannot bulge on the side because the material tensions evenly. This characteristic greatly reduces any damage to the side wall.
Owing the extensive use of internal harnesses, bulging of the top
and bottom is avoided. The strong, multi-layer and reinforced material avoids bag damage within the working area. The supporting
material of the lifting bag is made of ARAMIDE which is a very light
but tear-resistant articial bre.
The coating of the supporting material is made of NEOPRENE
which is a synthetic articial rubber. As opposed to material rubber, NEOPRENE has ideal characteristics for the lifting bag, e.g.:
9 High resistance to mineral oil and acid
9 High resistance to wear and has a long life cycle
9 Maintenance free
The exible lifting bags mould themselves to the shape of the
load to be lifted as opposed to hydraulic and pneumatic lifting
gear with their solid positioning plates. In connection with the
very low application pressure of only 1.0 kg/cm², loads can be lifted carefully.
Lifting bags, irrespective of the type, are unstable over the complete lifting distance! When using just one bag it must be positioned exactly under the load‘s centre of gravity otherwise load
movement cannot be avoided.
In practise, exact positioning is not possible!
If the use of one bag cannot be avoided then positioning stability
of the load is to be ensured. However, if two bags are used and if
one bag is placed to the front part and the other bag to the rear
part of the load then the centre of gravity will always be between
the two bags.
The basic condition for a stable, dierent control of both bags is
the separate independent control using the corresponding dual
controller.
