Abstract
Each tamping unit of the tamping machine has a gantry (6) which is inclinable transversely to the track and in which the tool holder (3) is mounted for vertical movement. The amplitude of the downward movement of the tool holder (3) is regulated by a device (16 to 21) controlled by a command level corresponding to the depth of tamping desired. In order to correct the differences (E) between the depth of tamping reached and that desired which are caused by the inlination of the gantry (6), the command level is lowered by a distance substantially equal to the differences by a correction device comprising a mechanical feeler (25) for detecting the inclination of the gantry (6) and a mechanical connection (26, 34) connecting the said feeler to the sensitive member (16) of the regulating device in order to vary the zero thereof. In a variant, this correction device is formed of an electronic circuit which permits the cancelling of the differences (E).
