Tamping head

摘要

A tamping head with a pair of vibratory and reciprocatory tamping tools mounted on a vertically adjustable carrier for immersion in the ballast in the cribs, with the ties positioned between the tools. Each tamping tool is constituted by a lever pivotal in a vertical plane about a transverse pivot, and stops are mounted on the carrier for setting at least three different reciprocating strokes for the tamping tools, with a remote-controlled multi-step drive for setting the stops.
