ABSTRACT:
The switching device which interconnects a substantially linear primary track with a curved branch track, wherein each such track possesses a travel rail and in a plane above each of the travel rails a guide track, comprises two pivotable or swivelable travel rail sections and a curved pivotable or swivelable guide rail section. The pivotable or swivelable travel rail sections are alternatively movable out of rest positions into travel positions in which such are located in recesses formed by stationary travel rail sections. The movable rail sections are mutually interconnected with one another and with an actuation rod by toggle levers or toggle joint structures and thus commonly actuatable. These toggle levers or toggle joint structures coact with abutments and enable locking the movable rail sections in their travel positions. The switching device affords quiet travel of the vehicles of the overhead cable transport installation and prevents derailing thereof.
