Abstract
Abstract A track crossing for a carriage of a two track suspension railroad arranged in a box girder has, on both sides of a slot provided in the lower flange of the box girder, running surfaces for support wheels, and at the sidewalls of the box girder, current rails and parallel guide surfaces for lateral guide rollers. For bridging and unused track two slewable support members with lateral guide surfaces and, optionally, running surfaces for the support wheels are provided. Current rails are arranged on at least one of the support members. The support members can be swung into depressions of the fixed sidewalls of the box girder of the one or the other track.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
143 words
In a track crossing for a carriage of a two-track suspension railroad arranged in a track girder, in which running surfaces for support wheels are provided on both sides of a slot provided in the track girder, through which a suspension connecting the carriage to a cabin passes, the improvement comprising: (a) the track girder being a box girder, at the sidewalls of which parallel guide surfaces for lateral guide wheels and current rails are arranged, (b) two settable support members having lateral guide surfaces for bridging the unused track pivoted for swinging motion at the mutually opposite sidewalls of the crossing track girders about vertical axes; (c) depressions in the sidewalls of the box girders in the one or the other track into which said support members can be swung; and (d) current rails on at least one of said support members.
Claim 2
Dependent Claim
