Introduction
Lifting bags may only be
operated with compressed-
air - or with water in excep-
tional cases -(accessories
on request), though never
with flammable or aggres-
sive gases. The lifting bags
may only be operated using
original Vetter fittings.
Mini-Lifting Bags (steel or
Aramide) of types V24 -
V31 - V40 - V54 - V68
(VS26 - VS34 - VS43 -
VS59 - VS74) fall under the
Pressure Vessel Legislation
from July 1st, 1980, in
Germany (DruckbehV).
These lifting bags may only
be put into operation after
submission of the manufac-
turer’s certificate of official
acceptance. This test
certificate should be kept in
a safe place and presented
to the test expert at the
repeat test.
Pay attention to DIN 7716 if
stored for longer periods of
time. We will be happy to
supply an excerpt from this
standard.
Safety instructions
•
Use only Vetter original
fittings. Only these have
been tested in the
works in accordance
with the Pressure
Vessel Legislation.
•
Please check the
perfect and correct
condition of the lifting
bags and accessories
before and after every
use.
•
Insert bags at suitable
points so that at least
75% of the bag’s
surface is beneath the
load.
•
Avoid angles larger than
30 degrees (relationship
between base and load
to be lifted). The bag
could be catapulted out
of the gap. Create a
parallel base to the load
to be lifted whenever
possible using a sturdy
substructure.
•
Never place more than
two bags on top of one
another.
