Description
3.1 Application
3.1.2

Lifting protection

The lifting protection prevents the load bearing implements from being lifted off of the load
cells.
If there is a risk of the load bearing implement being lifted or toppled, then lifting protection is
required. This is required in the case of lightweight containers and tall, outdoor silos.
3.1.3

Overload protection

The overload protection protects load cells from a load that is too great.
There is overload protection against excessive loads in the measuring direction and overload
protection against excessive transverse forces.
Transverse forces are caused by, for example, wind, filling processes, acceleration, or
conveyor belt friction. If these forces exceed certain values, the load cells must be protected
from them.
3.1.4

Use of the grounding cable

The grounding cable is used to protect the load cells from undesired currents. The causes of
such currents are, for example:
● Equalizing currents with missing or faulty equipotential bonding conductors
● A lightning strike nearby
● Welding work
● Static charge
