Trapper is equally suitable for stationary and in-motion, train-specific and wagon-specific weighing. Optimal accuracy is achieved when the train is weighed wagon by wagon while stationary. The scale system is also suitable for in-motion weighing of liquid cargo wagons thanks to its compensation for displacement of the centre of mass.

The Trapper train scale system also includes features that improve safety, such as an overload alarm and loading error alarms that can be triggered by loading errors related to individual bogies or load positioning. When the set alarm limits are exceeded, an error alarm is launched in accordance with the customer’s needs, e.g. with a sound signal or a text message.
