7.3.6 Load distribution
A small example: You are building a table with four lifting
columns. Each lifting column can bear 1000N. Thus, the lift-
ing columns together must bear a load Fmax = 4000N, 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 4000N under this corner.
This would lead inexorably 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 following fixing options are available for installing the lifting column:
•
RK
Powerlift
telescopic
Four M8 fixing borings in the base and cover plates respectively. The recommended bolt depth
is a maximum of 6 mm and the recommended torque 15 Nm.
•
RK
Powerlift
rack
Four
M10 bolt channels in the inner and outer sections respectively. The recommended bolt
depth is at least 25 mm and the recommended torque 25 Nm.
Preferred installation position:
Other installation positions are only permitted in agreement with RK Rose+Krieger GmbH.
•
RK
Powerlift
spindle
Four M10 fixing borings in baseplate and four M10 bolt channels in the inner section. The
recommended bolt depth is a maximum 9 mm in the baseplate and at least 25 mm in the in-
ner section and the recommended torque 25 Nm.
For guaranteed rigidity, it is essential to stipulate an adequately dimensioned foundation to ab-
sorb the stated maximum compressive and tensile forces and the torque loading. (see section 6.2)
