2.5 Correct handling and usage
Lifting bags are mainly pneumatically driven rescue equipment
for the rescue services (e.g. fire service) with which trapped peo-
ple can be freed, paths made to carry out rescue or counter-mea-
sures etc. The lifting bags can also be used as working equipment
to lift or move objects.
Lifting bags meet the requirements specified in DIN EN 13 731 as
well as GUV-G 9102 in the field of fire services. Further operational
instructions are specified in the operating manual of the user.
2.6 Safety instructions
The prespecified protective clothing is to be worn during the ope-
ration. National regulations connected with the lifting bag sys-
tems and their operation are to be observed.
Lifting bags are only to be used with compressed air. Under no
conditions are inflammable or aggressively acting gases to be
used. The lifting bags must only be inflated with original Vetter
fittings because these are subjected to an acceptance test by the
manufacturer. The lifting bag system is to be checked before and
after operation to determine whether it is in perfect condition.
Never lay two or more lifting bags
on top of each other.
Ensure that the load does not slip. Gravitationally support loads
being lifted during a continuous lifting procedure. Always pay
particular attention to the stable condition of the support materi-
al during support work.
The support structure must at least support
the whole area of the bag and must be larger
in its length and width than in its height!
Attention danger of slipping! Never place
metal on metal when carrying out support work!
Place stones, branches or similar items under the bag in order to
increase ground grip when the ground is slippery (ice, snow, mud
etc.). Avoid pointed loads such as grips or screws.
Attention danger of slipping! Never place
metal on metal when carrying out support
work!
Never place the bags on sharp edges or hot to red hot compo-
nents. Use suitable intermediate layers and cover the whole be-
aring area of the bag. Protect the bag from sparks from welding
or separation work. Do not additionally subject the bag to such
things as hydraulic stamps, hoists, falling loads etc.
