The trailer (15) has a loading surface (19), load rollers (18) and a tongue (17) coupled to a tractor (1). A determination device determines dead weight of the trailer, and a loading weight sensor (22) determines weight of load of the trailer. An energy supplying device supplies energy to the weight sensor. A transmission device or transmitter transmits information about the dead weight and/or the weight of the load of the trailer to a receiver. The supplying device has a dynamo or a battery, and the transmission device has a cable connection between the trailer and the tractor. The weight sensor is designed as a piezoelectric pressure sensor, piezoresistive pressure sensor, frequency-analog pressure sensor, capacitive pressure or inductive pressure sensor. An independent claim is also included for a tractor-trailer comprising a tractor and a trailer. |
