Definitions

• the invention relates to a machine for processing a ballast bed or of a formation for a track formed by rails and sleepers, with one Machine frames that can be moved continuously thanks to rail bogies on the track and a track lifting device arranged between two rail bogies, those for lifting the track by drives adjustable in height with the machine frame is connected, and a - around a cross machine direction Axis rotatable - rolling element for supporting the sleepers of the track.
• Such a machine is already known from US-A-1,899,874, in connection with a ballast cleaning the track continuously with the help of the track lifting device is lifted off the ballast bed.
• the track lifting device sets are made up of a large number of arranged one behind the other in the machine longitudinal direction Rolling elements put together by positioning them below the track for support serve the thresholds.
• a machine for ballast cleaning is also known from CH-A-291134, the track lifting device consisting of two spaced apart in the cross-machine direction, skid-like sliding bodies is formed, which is below the track for support are positioned.
• Another machine is already known from US-A-4,479,439 and is used for Replacing a track ballast bed with simultaneous application of a formation protection layer.
• the continuously movable machine frame is at the end supported on rail bogies and with other transport vehicles to one System coupled, one of the trolleys for the purpose of increasing the span can be raised between the support points of the machine frame.
• the track is raised to below the thresholds to create enough space for the bed processing units, that from a clearing chain to expose the formation as well as height-adjustable grading devices for leveling and compacting what has been dropped on the formation There is sand and gravel.
• the track lifting device has for guidance or mounting of the track grate can be swiveled laterally at the desired height on, which is swung in like pliers from both sides under the rail head and remain in constant engagement with the rails. If necessary occurring changes in the rail cross section, such as when driving over a rail joint, however, the positive one Contact of these so-called roller tongs with the rail head disturbed are and thus the continuous support of the track is not guaranteed stay.
• From US-A-3,179,062 is another machine for processing a track bed known, essentially from a below the track grate in the longitudinal direction there is a wedge-shaped, device having a frame.
• This device is supported by height-adjustable, connected to the frame driven crawler tracks on the gravel or formation surface, which leveled by broaching tools located at the front end of the device becomes.
