Claim of US Patent No. 10,557,762

1. A device for monitoring wear on an overhead line, comprising a force measurement system comprising:two contact bars oriented at a right angle to the overhead line;
two connection bars having first and second end portions which are oriented in parallel relation to the overhead line and pushed upwards to thereby press the two contact bars against the overhead line at a predefined force; and
bar-shaped force transducers respectively arranged at the first and second end portions of the two connection bars for arrangement of strain sensors, each said force transducer having first and second end portions, wherein
the first end portion of two first ones of the force transducers is connected to one of the contact bars,
the first end portion of two second ones of the force transducers is connected to another one of the contact bars,
the second end portion of one of the first ones of the force transducers is connected to the first end portion of one of the connection bars,
the second end portion of another one of the first ones of the force transducers is connected to the first end portion of another one of the connection bars,
the second end portion of one of the second ones of the force transducers is connected to the second end portion of another one of the connection bars,
the second end portion of the other one of the second ones of the force transducers is connected to the second end portion of the one of the connection bars,
the one of the first ones of the force transducers and the other one of the second ones of the force transducers defining a longitudinal axis which extends in a direction of a longitudinal axis defined by the one of the connection bars, and the other one of the first ones of the force transducers and the one of the second ones of the force transducers defining a longitudinal axis which extends in a direction of a longitudinal axis defined by the other one of the connection bars, said longitudinal axes of the force transducers extending in a travel direction of a rail vehicle in contact with the overhead line.
