Patent number: 8979083Abstract: A welding unit for welding two rails of a track is equipped with clamping jaws intended for lying against a rail web. The clamping jaws each have a sliding surface, which is at a distance from a contact surface in the transverse direction of the rail and is arcuately curved with respect to a cross section extending such that it is normal to a neutral axis of the rails. The jaw mount, intended for fixing the clamping jaw, has a sliding surface, which is curved in a way corresponding to the sliding surface of the clamping jaw, and so the clamping jaw is movable along the sliding surfaces in relation to the jaw mount.Type: GrantFiled: November 13, 2009Date of Patent: March 17, 2015Assignee: Franz Plasser Bahnbaumaschinen-Industriegesellschaft mbHInventors: Josef Theurer, Bernhard Lichtberger, Heinz Mühlleitner

Patent number: 8240253Abstract: The compression of ballast for a rail track takes place after two-stage cleaning by a cleaning machine. For this purpose, cleaned ballast is dispensed and a first ballast layer is thereby formed. The rail track which is laid on the first ballast layer has lateral oscillations imparted to it by a front stabilization unit, and the first ballast layer is thereby compressed. The formation of a second ballast layer takes place by a second chute, which second ballast layer is subsequently compressed by a rear stabilization unit.Type: GrantFiled: October 17, 2008Date of Patent: August 14, 2012Assignee: Franz Plasser Bahnbaumaschinen-Industriegesellschaft mbHInventors: Josef Theurer, Herbert Wörgötter

Patent number: 8186070Abstract: For the controlled lowering of a track, a longitudinal inclination of the track is determined at a rear tracing point of a measuring system and stored. For a length reaching back at least 10 meters, a current vertical profile is formed, and a rear compensation straight line is calculated which is superimposed upon the vertical profile and renders a target track position. The rear tracing point is guided by calculation along the rear compensation straight line, so that a compensation value for the position of the measuring chord ensues at a middle tracing point positioned between the rear tracing point and a front tracing point.Type: GrantFiled: October 8, 2009Date of Patent: May 29, 2012Assignee: Franz Plasser Bahnbaumaschinen-Industriegesellschaft M.B.H.Inventors: Josef Theurer, Bernhard Lichtberger
