Inspections

The following inspections are to be carried out.

Weekly inspections by operator

1. If yearly service has been carried out, make sure that the service inspection date is valid.
2. Check all bolts and nuts for damage or wear.
3. The top swivel joint includes a safety valve. The valve automatically closes if the power fails and
the load sinks to the floor under control. Check the operation of the safety valve by lifting a load
approximately 1 m., close the operating handle fully, and then stop the vacuum pump. The load
should be equivalent to the rated max lifting capacity and of a non-porous material (for example,
a steel plate). A controlled sinking motion is correct – anything else: do not use the lift and con-
tact your vacuum lifter dealer immediately.
4. Check all connecting components (clamps between lift tube and suction head, clamps between
lift tube and top swivel, clip and pin in crane system trolley eyelet, air tube clamps, bolts for suc-
tion foot).
5. Clean the air filters (filter unit and suction foot), more often if the working environment demands
it.
6. Check the lift and air tubes for signs of damage or wear. A damaged lift or air tube must be re-
placed immediately.
7. Check that the max lifting capacity, warning and operating signs are visible.
8. Make sure the lift runs smoothly in the crane system or jib rig.
9. Make sure that the operating valve is functioning properly.
10. Check that the vacuum lifter achieves maximum lifting capacity. The designated load should be
easily held by and lifted with the vacuum lifter. Lifting capacity is reduced if a vacuum leak oc-
curs. See trouble shooting for more info.

Quarterly inspections by inhouse maintenance

1. Double check (carry out) all inspections mentioned in Weekly inspections by operator.
2. Check the lift and crane system or jib rig for signs of damage/wear and that bolts and pins are
tightened and in place.
