Vetter Ultra Flat Bags 8 bar (116 psi) - Manual (Page 9)

Page 8/16
Vetter Ultra Flat Bags are only to be inflated with original Vetter
inflation fittings because these were subjected to an acceptance
test by the manufacturer. The lifting bag system is to be tested
for perfect condition before and after use (specifications from the
manufacturer, national regulations).
The lifted load is to be continually supported during the proges-
sive lifting sequence. The stable condition of foundation support
material must always be observed during construction of the
foundation support.
Never position 3 or more bags on top of each
other!
Ensure load against slippage.
In order to fully use the strengths of the Ultra Flat Bag, the dis-
tance between load and bag should be at a minimum.
The foundation support must brace at
least the complete area of the bag and the
smallest edge length of the foundation
support must be larger than the height of
the foundation support. Metal must
never be place on metal!
Attention: danger of slipping!
With slippery ground (ice, snow, mud etc.) place anti-slip materials
under the bag in order to increase adhesion. Point-shaped loads
are to be avoided, e.g. construction claws or screws. Never place
the bags on sharp edges, hot or red hot components. Use suitable
temporary storages and cover the complete contact area of the
bag. Protect the bag against flying sparks during welding or se-
paration work. Do not additionally load bags with such things as
hydraulic lifting devices, winches or falling loads.
Never remain beneath a lifted load, never hold
the load from below!
Remain at a distance!
Avoid shearing effects by squeezing of the bag when lowering the
load!
During operation never stand in front of
the bag but always to one side, because the
bag could catapult outwards under
unfavourable conditions!
The lifting sequence is to be stopped
immediately if there is a function failure!
A Ultra Flat Bag can burst under adverse conditions with incorrect
operation, incorrect handling or by manipulation on the control-
ler and/or inflation hose (problems concerning pressure waves
and sound waves, uncontrolled movement)!
