摘要 |
The machine comprises at least two pairs of vibrating tamping hammers (40-41), each rigidly associated with a support (38-39) oscillably pivoted to the frame (30) of the machine and subject to the action of a fluidodynamic actuation jack (42-43) comprising a first extendable section, adapted to move the hammer from a substantially vertical working position to a substantially horizontal lowered idle position, and a second section, fed by distribution means with alternating cyclic operation, adapted to subject said first jack section and the related tamping hammer to a corresponding cyclic and alternating vibration. |
