Example 1: Container weighing

The total center of gravity S of the suspended container lies above the level of the load cells.

It is supported on 4 brackets (container manufacturer specification), has an empty weight (dead load) of 1.2 t (1.18 tn. l.), and a maximum capacity of 1.8 t (1.77 tn. l.). The load is evenly distributed across all 4 load cells.

Note

The three-point bearing of the container is statically determined and represents a stable state (see comment in the introduction).

Selection of load cells and mounting components

The determination of the rated load, as described in the introduction, results in a rated load of 1 t (0.98 tn. l.).

Container on SIWAREX WL280 RN-S SA load cells and compact mounting units

For the above example, 4 SIWAREX WL280 RN-S SA load cells were used with a rated load of 1 t (0.98 tn. l.), because the high-quality precision RN load cells have an extremely low constructional height.

Self-centering compact mounting units are used as mounting components because, in addition to their oscillation function and oscillation limitation, they are also fitted with anti-lift protection. The anti-lift protection can absorb a maximum vertical force of 4.2 kN. In the event of greater lifting forces (e.g due to wind load), the container must be safeguarded with additional catastrophe protection.
