3.4.3 Anchoring lifting columns
1. Use suitable means to raise the lifting carriage
to the first latching position. All the mounting holes
in the base plate are then accessible.
!
Make sure the locking pawl is engaged.
2. Check the position of the base plates again.
3. Drill the mounting holes. Remove the drilling dust
from the hole.

4. Use a spirit level to check the vertical alignment of
the lifting columns. If necessary, place equalizing
plates under the base plates.
!
The equalizing plates must be of the same length
as the side of the base plate resting on them. Oth-
erwise the load of the base plate will not be trans-
ferred evenly to the foundation.
5. Use shear connectors to secure the base plates
of the lifting columns to the foundation.
