Application planning

3.1

Load cell dummies

Principle of operation
Load cells are sensitive sensors. To protect the load cells from becoming damaged during
installation and transport, install the load cells only at the last minute. Replace the load cells
during installation and transport with placeholders, so-called dummies or phantoms.
Dummies might be designed as follows:
● A copy of the compact mounting unit by means of a welded construction for coarse
installation work
● Use of a SIWAREX compact mounting unit for light installation work
A copy of the compact mounting unit by means of a welded construction for coarse installation
work
A piece of pipe or some other steel profile is welded between two plates with the hole pattern
for the fixing screws. The total height corresponds to the installation height of the compact
mounting unit. This is the most stable and secure version. Rough installation work can be
carried out with the welded construction.
Use of a SIWAREX compact mounting unit for light installation work
The compact installation units are delivered pre-assembled. Compact installation units are set
to the installation height of the operational unit. With compact mounting units, light installation
work can be carried out.

Lifting protection

The following figure shows a proposed solution for lifting protection. The X designates the
possible lifting path of the load bearing implement. The bore ØD must be larger than the
diameter of the bolt Ød. The movement of the load bearing implement must not be hindered.
