Abstract

An electrohydraulic actuator for level crossing barriers, with a working cylinder whose piston is movable by the pressure liquid that can be taken from a reserve vessel through a hydraulic distributor block with a channel system of a pump driven by a reversible electric motor, making a piston rod straight rotate the shaft of the lifting barrier through an oscillating arm fixed on them, characterized in that the electric motor, the pump, the reservoir and the hydraulic distributor block form a compact unit, only high-pressure lines, in particular electrically insulating, being provided between said unit and the working cylinder.
