4.1

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.

4.2

Lifting protection

Lifting protection is integrated in the compact installation units for the load cells of the

SIWAREX series. When other compact mounting units are used, lifting protection must be

provided for in the design.

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.
