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.

A tensioning, system for a traction track of a machinery comprising:
- a hydraulic cylinder applying a tensioning force on at least one wheel on which said track is wound according to a closed chain configuration wherein said hydraulic cylinder is fed with different pressures according to the traction direction:
- in a first traction direction said feeding pressure of said tensioning hydraulic cylinder being a first pressure approximately corresponding to the pressure which is generated by a boosting pump of a closed circuit feeding the traction devices;
- in a second traction direction said feeding pressure of said tensioning hydraulic cylinder being a second pressure approximately corresponding to the pressure of said closed circuit.
