VIAVAC vacuum lifting BV T. + 31 348 449 660 E. [email protected] I. www.viavac.com
Before any lift, the user must check the following:
I.
Check the rubber sealing profile of the suction pad for damage and cracks, replace if necessary.
II
Check rubber back plate of the suction pad to verify whether it is clean and free from grease, oil or
water drops and, if necessary, to clean it up.
III
Whether the battery is sufficiently charged; The volt meter (8) must indicate between 11 and 13 Volt.
IV
Functioning of the acoustic alarm (11) at a vacuum level below -0.60m bar.
This can be checked by briefly putting the control lever (8
) in the position “
suction
” (green area)
before the suction pad is placed on the load.
Remove excessive water, snow and ice at the area where suction pads are placed on load.
This is essential to have suffucient friction needed for lifting in vertical or inclined position.
If the load has a protective film, it must first be removed before the suction pad is placed on the
load.
During every lift the operator must constantly monitor the following:
a.
Vacuum meter, during lifting the pointer must constantly remain in the green area.
b.
Acoustic alarm signal; during the lift it may not be audible.
If the vacuum meter is in the red area and/or the acoustic alarm signal sounds, do not lift!
If the vacuum meter is in the read area and/or the acoustic alarm signal sounds, a lifted load must be
put down as quickly as possible.
If the vacuum pump for some reason fails, from the moment the vacuum level
decreases below the required level of> -0.60, the load will be held for a minimum of 5 minutes.
To work safely with the device, it is therefore necessary that:
- The operator must have good hearing and is not using hearing protection.
- During the lifting the operator must be within hearing and visibility distance of the device.
-
The ambient sound does not amount to more than 70db.
-
The operator of the device is constantly in contact with the operator of the lifting machine and
agreements have been made about a clear communication.
Protective precautions at operation temperatures between the -10
o
C and 0
o
C.
- To prevent clogging of the filters, it has to be ensured that all the humidity has been removed from the
device. This is achieved by letting the vacuum pump run approx. 15 minutes with the control level (9) in
the position “suction” in a dry and heated compartment.
-
To be assured of sufficient battery capacity, store the device at a temperature of 15
o
C or higher at night.
- For sufficient friction between suction pad and the load, it must be ensured for every lift that both the
suction pad and the suction surface of the load, all water, snow and ice is removed.
