ROADWAY LIMITING ELEMENT AND METHOD FOR OPENING A ROADWAY LIMITING ELEMENT AND USE OF A FLUIDICS DEVICE FOR OPENING A ROADWAY LIMITING ELEMENT

摘要

The invention relates to a roadway boundary element (100) which comprises a stationary element (10) and a telescopic element (20). The telescopic element (20) can be moved relative to the stationary element (10). The telescopic element (20) can in particular be displaced into a guardrail element (40). The telescopic element (20) and the stationary element (10) are connected or connectable by means of a locking device (30). The locking device (30) is connected to a fluid technology device (50) by means of a force transmission element (80), in particular a traction mechanism drive (80). The locking device (30) and the telescopic element (20) can be moved by the fluid technology device (50). The fluid technology device (50) comprises a pressure accumulator (51).
