Are the scales sensitive against external force?
No, so far no scale / load cell have been replaced due to external force. If the angel on the bin lift is changed the scale only needs to be recalibrated to work correct again. The scales have at minimum 400% overload capacity. On the FEL there have been some accidents were the driver forgot to tilt down the forks and have been driving in to bridge, with the result that the forks look like ” 2 S “, but still the scales work.
