Load transporting trailer e.g. solid manure spreading machine, for use with agricultural tractor, has calculating box connected with sensor to calculate load carried by structure based on compression ratio measurement of compressible unit

摘要

The trailer has a weighing system (5) comprising a connecting device (6) to connect a floor of a bearing structure (2) and a mechanical anchoring system or an axle. An elastically deformable compressible unit (7) occupies rest and compressed configurations in rest and loading positions of a set of connection units of the weighing system, respectively. An inductive proximity sensor (8) measures a compression ratio of the compressible unit between its configurations. A calculating box is connected with the sensor to calculate a load carried by the structure based on the measurement. The connection units are formed of a rod (63), two support parts (64) and a connecting rod (65). The compressible unit is formed of Belleville washers and compression springs.
