BALLASTSTOPPARE VID JERNVEGAR

摘要

A tamper has tamping tools intended for tamping the open track and the switch gear. Each tool is mounted on an oscillating and pivoting lever (6) and has a fixed pick (20) and a pick (21) displaceable by pivoting in a plane transverse to the track around a shaft (23) which is rigidly connected to the lever (6) and by means of a cylinder (26). The tappets (22) of these picks are offset and partially cover one another in the close-together position and the picks are arched towards the outside so as to leave sufficient space between them for the flow of the ballast above the tappets. The switch gear is tamped in close-together position of the tappets over a reduced length (R) and the open track is tamped in spaced position over a greater length, the stroke of the cylinder (26) limiting and defining these two positions.
