FIELD: hydraulics.
SUBSTANCE: invention relates to machine building hydraulics, in particular, to hydraulic drives of mobile machines with multiple actuating mechanisms. The working ports 7 of the hydraulic motor 6 are connected with the drainage port 12 thereof via a normally open distributor 13, the control cavity 14 whereof is connected with the control port 5 of the parking brake 4.
EFFECT: invention is aimed at providing the possibility of heating the hydraulic motors of idle mechanisms when work is performed by other mechanisms.
