FIELD: transport.
SUBSTANCE: invention relates to handling equipment, particularly, to turning mechanisms with hydraulic drives. Proposed mechanism comprises revolving column with gear, rack arranged inside hydraulic cylinders equipped with dampers fitted in their pistons. Hydraulic cylinder covers are provided with channels communicated with control valve of basic machine hydraulic system and with chambers of extra damper. Turning mechanism is furnished with extra air cylinders including pistons fitted on rods composed of rack engaged with revolving column gear.
EFFECT: power recovery accumulated in pistons in outage of hydraulic cylinders at finite positions.
