Vetter Lifting bags 1 bar (14.5 psi) - Manual (Page 9)

Page 8/15
If the movement height or the movement area is not sufficient for
correct application of the lifting bag, then the required space can
normally be quickly obtained by using the Vetter Mini Lifting Bag
8 bar.
4. Operating Instructions
4.1 Operation with compressed air bottle
200 bar or 300 bar
Connect the pressure reducer to the compressed air bottle, 200
bar or 300 bar, using the tommy screw (1). Close the hand wheel
of the pressure reducer (2). Open the valve on the bottle (3). The
pre-pressure manometer (4) indicates the pressure in the bottle.
Adjust the back pressure to approximately 2 bar with the regula-
tion bar (5) (indication of the reduced pressure on the back pres-
sure manometer (6)).
Connect the air hose of the pressure reducer via the nipple to the
input coupling (7) of the controller. In doing this, press the nipple
into the coupling until you feel it lock in. For additional safety: turn
the brass sleeve (8) so that it is opposite the safety pin (9).
Open the hand wheel (2) of the pressure reducer.
The lifting bag system is ready for operation.
To inflate the lifting bag pull the lever (11) back, resp. slowly open
the ball valve of the fitting controller. Observe the manometers
(10) and the load.
If the required pressure is reached for lifting or if the lift height is
achieved, then end the inflation sequence by releasing the switch
lever or close the ball valve. Latest when the safety valve blows off
or the red marking is reached! The switch lever of the controller
with the deadman switch will automatically go back to the zero
position.
An integrated safety valve will automatically activate when the
bag is unintentionally over-inflated above the maximum opera-
ting pressure (1.0 bar/14.5 psi) or when there is an increase in bag
pressure due to additional loading of the bag. The activation tole-
rance for opening and closing of the safety valve must not exceed
+/- 10%.
Press the switch lever to „Deflate“ in order to deflate the bag or to
lower the load.
Load behaviour and lift movement must always be continuously
monitored. Depending on the type, position and behaviour of the
load during the lifting sequence, the lifting bags are either
9 simultaneously and evenly inflated or
9 inflated step-by-step, resp. individually.
