Abstract

A switch tamping machine comprises a machine frame, a track lifting and lining unit operated by lifting and lining drives linking the track lifting and lining unit to the machine frame, and at least one ballast tamping unit mounted on the machine frame for displacement transversely to the direction of elongation of the machine frame. The tamping unit comprises a carrier frame, a tamping tool carrier vertically adjustably mounted on the carrier frame for vertical displacement along a vertical guide, and a pair of vibratory tamping tools mounted on the tamping tool carrier for reciprocation in the direction of elongation. An auxiliary lifting device is vertically adjustably mounted on the carrier frame of the transversely displaceable tamping unit for lifting a switch rail transversely spaced from the machine frame, the auxiliary lifting device comprising a vertically adjustable rail engaging tool, and a lifting drive links the auxiliary lifting device to the carrier frame.

A switch tamping machine comprising

(a) a machine frame extending in a direction of elongation and supported on undercarriages for mobility on a track resting on ballast,
(b) a track lifting and lining unit,
(c) lifting and lining drives linking the track lifting and lining unit to the machine frame between the undercarriages,
(d) at least one ballast tamping unit mounted on the machine frame for displacement transversely to the direction of elongation, the tamping unit comprising
(1) a carrier frame,
(2) a tamping tool carrier vertically adjustably mounted on the carrier frame for vertical displacement along vertical guide means, and
(3) a pair of vibratory tamping tools mounted on the tamping tool carrier for reciprocation in the direction of elongation,
(e) an auxiliary lifting device vertically adjustably mounted on the carrier frame of the transversely displaceable tamping unit, for lifting a switch rail transversely spaced from the machine frame, the auxiliary lifting device comprising
