FIELD: mechanical engineering.
SUBSTANCE: drive comprises two front and two back hydraulic bearings mounted on the platform, controlled check valve whose above-valve spaces are in communication with the piston spaces of the hydraulic bearings through pipelines, throttles with check valves, power source, and three-way distributors whose inlet openings are connected with the piston spaces of the hydraulic bearings. The throttle with the check valve is mounted in series to each throttle in the respective main line. First outlet opening of the third three-way distributor is in communication with the under-valve spaces of the controlled check valves of the hydraulic bearings mounted along one of the sides of the platform. The second outlet opening is connected with the under-piston spaces of the hydraulic bearings and control chambers of their controlled check valves.
EFFECT: expanded functional capabilities and enhanced reliability.
