摘要:
Railway switches are subjected to a high degree of stress due to the influences of weather and as a result of trains traveling over them. This may result in changes in adjustments and settings made at the time of mounting. In order to permit, in particular in the case of hollow sleepers, simple re-adjustment of a drive rod relative to the cam rods, an attachment element can be connected to an attachment flange by a positive lock, formed by various adjustment keys and a main key, and using locking screws in such a way that fine adjustment by appropriately selecting the arrangement of the adjustment keys is possible. Coarse adjustment is made by an asymmetric arrangement of the bore holes for connecting to a drive rod as well as by selecting one of the two bore holes.
