ABSTRACT There is described a track lifting and aligning clamping device for a railroad track. The clamping device is mounted transversely beneath a longitudinally extending main frame of a track working machine and includes a transversely extending track aligning sub-frame which carries rail engaging wheels to support the sub-frame on the rails of a track. Railhead contacting members are provided on either end of the sub-frame to contact the inside of each rail head and one of the contacting members is biased outwardly of the sub-frame to accommodate changes in rail head spacing. Mounted on vertically extended guide rods at the ends of the sub-frames are rail lifting hook guide members which are arranged for vertical sliding movement on guide-rods on the sub-frame and carry, within the guide member a guide-rail which extend transversely of the track and on which a rail hook is slidingly mounted for movement transversely of the track. Hydraulic piston and cylinder means are connected between the top of the rail hooks and the sub-frame and act to slide the rail hooks in and out towards the outsides of the rails, transversely of the track. Track aligning jacks are connected between the sub-frame and the main frame to move the sub-frame from side to side to cause the rail head contacting members to push against the rail heads to move the track to the left or right to align it and track lifting jacks are connected between the main frame and the guide members and act to lift the guide members with their hooks so that the hooks engage beneath the outsides of the heads of the rails or beneath the rails to lift the track to a desired height.
