Patent number: 6619405Abstract: A ballast cleaning machine comprises a first machine frame and a second, trailing machine frame linked thereto. Ends of the machine frames are supported on the track by undercarriages for movement of the machine in an operating direction. A vertically and laterally adjustable endless excavating chain as well as a track lifting device is mounted on each machine frame. An upper layer of the ballast bed is excavated by the first excavating chain, the track is lowered to the remaining ballast bed layer, and the remaining ballast bed layer is immediately thereafter excavated by the second excavating chain. The excavated ballast is cleaned in a common screening installation, and the cleaned ballast is distributed at a trailing end of the second machine frame to the ballast bed.Type: GrantFiled: March 15, 2002Date of Patent: September 16, 2003Assignee: Franz Plasser Bahnbaumaschinen-Industriegesellschaft mbHInventors: Josef Theurer, Herbert Wörgötter

Patent number: 6047531Abstract: An apparatus for cutting vegetation under railway tressels and roadways that includes a vehicle chassis having a turntable body mounted thereon. A primary control station is mounted on the turntable body along with a main boom with a vegetation cutting head attached and a second elevating boom with a secondary control station suspended therefrom. Operators man each of the control stations, and the main boom and elevating boom are hydraulically controlled from either of the control stations as the operators cut vegetation from about railway tressels or roadway overpasses while communicating via a two-way intercom system between the control stations. When cutting below the line of sight of the operator in the primary control station, the cutting head is controlled by the secondary control station operator or is lowered by the elevating boom to a level giving a clear view of the vegetation being cut.Type: GrantFiled: January 8, 1999Date of Patent: April 11, 2000Inventor: William Bryan, III
