  • Automatic tensioning system of tracks of a paver finisher
    Patent number: 9789918
    Abstract: A tensioning system of traction tracks of a machinery by means of a hydraulic cylinder applying a tensioning force on at least one of the wheels on which the track is wound according to a closed chain configuration in which the hydraulic cylinder is fed with different pressures according to the traction direction, in a first traction direction the feeding pressure of the tensioning hydraulic cylinder being a first pressure approximately corresponding to the pressure which is generated by a pump which is present on a closed circuit feeding the traction devices, in a second traction direction the feeding pressure of the tensioning hydraulic cylinder being a second pressure corresponding to the pressure of the closed circuit up to a predetermined upper limit value.
