FIELD: transportation.
SUBSTANCE: hydraulic control system with hydraulic control system of rotating-coupling device comprises a gear wheel pump with a drive gearbox, a cardan shaft, a hydrocyclone, two dampers, four power hydraulic cylinders, a tank, a safety valve, two slide valves, hoses and pipelines and it is additionally equipped with two power hydraulic cylinders of section relative rotation around the longitudinal horizontal axis of the machine. The cavities of the additional hydraulic cylinders are hydraulically connected to the system pump via a three-position control slide valve.
EFFECT: increasing flotation and profile possibility of the two-section track-laying machine by controlling the relative rotation of the sections about the longitudinal horizontal axis when driving in difficult road conditions.
