Abstract (en)
[origin: EP0298049A1] Ridging device for earthing up the ballast of a railway, wherein the vibro-compression implements (2, 2a) are linked to an implement carrier frame which is connected to a platform (3) by means of vibration-dampings. Platform (3) is provided at the upper side with a member (26) engaging an adjustable jib of a motor crane and at the lower side with a supporting member (4) lying on the rail. Platform (3) supports an oleodynamic motor which rotates by a belt pulley an eccentric flywheel shaft freely rotating on frame (1). The opposed pairs of hammer implements of the known type are driven by oleodynamic cylinders. Motor and oleodynamic cylinders are operatively connected to the oleodynamic power source of the motor crane. The ridging device can be used as a normal implement with articulated arm, such as a bucket or the like.
