METHOD AND TRACK-BUILDING MACHINE FOR RENEWING SLEEPERS OF A TRACK FORMED FROM RAILS AND THE SLEEPERS

摘要

In a method for renewing sleepers of a track formed of rails and the sleepers, the placement of skids, which support a machine frame of a track-building machine on the sleepers, is preceded by the machine frame being intermediately supported on the sleepers. The two rails are then distanced from one another, while avoiding a breakage separation, in a track section that includes both the region of the skids and the intermediate support. After supporting the machine frame on the skids, the intermediate support is lifted off the sleepers and work is begun.
