The lifting power - load path
diagram (cf. P. 31) facilitates
the choice of the suitable
bag size.
The curves shown refer to
the complete lifting of the
overall load at 8 bar (116
psi). If the weight is un-
known or the bag is used in
an emergency which calls
for quick action the largest
possible Mini-Lifting Bag
which fits under the load
should be used.
Levering requires
less force than
lifting!
In a number of cases the
load can still be levered
even though the lifting
power of the lifting bag is
not enough to lift the load.
Increasing the lifting
power and lifting
height
A maximum of two bags
can be placed on top of
one another in order to
increase the lifting height.
The lifting power of the
smaller bag on top is
hereby decisive for the
overall lifting power. The
lifting heights are added
together correspondingly.
In order to increase the
lifting power the bags have
to placed along-side one
another under the load.
If two or more bags are
placed alongside one
another the lifting powers
are added together. The
lifting height which can be
achieved depends on the
smallest bag used.
Vetter Mini-Lifting Bag
8 bar (116 psi) - Vetter
System
With the Vetter system the
arrangement of controller,
inflation hose and bag is
retained consistently
throughout the whole range
of Vetter products so that
bags cannot be inflated
with an excess operating
pressure by bypassing the
controller or even by
directly connecting the
pressure reducer to the
bag. The controllers have
safety valves and mano-
meters matched to the
respective pressure range
which prevent overinflation
of the bags.
There is a corresponding
controller with matching
coupling system for every
pressure range in the Vetter
system.
The green air supply hoses
between the controller and
air source have been
standardised for all pres-
sure ranges.
The inflation hoses in the 8
bar (116 psi) system are
available in the colours
yellow or red. The different
colours avoid confusion
when controlling the
individual bags.
Yellow or red = inflation
hose 8 bar (116 psi) from
controller to Mini-Lifting
Bag. (Different colours
make for easier recognition
when two bags are used).
