FIELD: electrical engineering. SUBSTANCE: in correspondence with proposed way reeling and unreeling of cable are controlled with the aid of driving and steering controlling aids of vehicle. Gear has one unreeling valve which is connected in series with hydraulic motor and is used to regulate backpressure of working fluid flowing through hydraulic motor during unreeling of cable from drum and one reeling valve which is employed to adjust amount of pressure fluid flowing into hydraulic motor during reeling of cable. EFFECT: avoidance of change of tension of cable and its change with acceleration and braking of vehicle, keeping tension of cable same. 11 cl, 2 dwg
