FIELD: construction.
SUBSTANCE: vibration roller is connected to a caterpillar tractor. The roller's hydraulic system is connected to the hydraulic system of the caterpillar tractor. In the pump station of the caterpillar tractor there is an axial-plunger hydraulic pump. On the rear bridge of the caterpillar tractor there is a hydraulic cabinet installed to control a vibration roller, in which a hydraulic distributor is installed, as well as a safety hydraulic valve to discharge excessive pressure developed in the hydraulic system of the vibration roller to the hydraulic system of the caterpillar tractor.
EFFECT: higher reliability in operation.
