7.3.6 Load distribution

A small example: you are building a table with four lifting
columns. Each lifting column can bear 1000 N. Thus, the
lifting columns together must bear a load Fmax = 4000 N, if
the load is symmetrically in the centre of the table. If the load
moves into a corner of the table, then the lifting column has
to bear almost the entire load of 4000 N under this corner.
This would inevitably lead to overload. Even at the planning
stage of your application, pay attention not only to the total
load, but also the load on the individual lifting columns.

7.4 Installation

The fixing boreholes for installing the lifting columns are located in the fixing plates of the lifting
column. The fixing screws are not included in the delivery.
The tightening torques to be observed can be obtained in the chart in chapter 7.4.1.
