Abstract

An apparatus for reducing a gap between an end of a rail section and an adjacent end of a longitudinally succeeding rail section of a rail fastened to ties by fastening elements by tensioning or longitudinally extending the rail section comprises two longitudinally spaced beams extending transversely to the track rails, a pair of clamping members mounted on each transverse beam for pivoting about parallel vertical axes at respective sides of the rail sections of the rail and having cooperating clamping jaws for engaging the rail sections between the clamping members upon pivoting thereof, the pairs of clamping members being longitudinally spaced from each other, hydraulic drives interconnecting the clamping members at each side of the rail sections of the rail, and a rail centering mechanism affixed to each transverse beam in the range of each pair of clamping members, each rail centering mechanism comprising at least two independently operable hydraulic cylinders carrying rams adapted to be pressed against at least one of said track components of the rail upon operation of the hydraulic cylinders.
