Zusammenfassung: | A tamping machine comprises: a rolling chassis (1) equipped with standard drawgear, (7, 8) at each end; tamping tools (12) mounted overhung in working configuration for reasons of economy and simplicity; and mechanisms for lifting (31) and withdrawal (18, 19, 22, 23, 27) of its tools (12) on its rolling chassis in order to retract them in configuration of travel to the work site. The withdrawal of a bracket (16) on which there is suspended a gantry (14) supporting the tamping tools causes the upward swinging of this gantry by the action of a connecting rod (31) connecting the bottom of the gantry to an arm (29) fastened below the rolling chassis. |
