Passage opening and closing device for roadway boundary, has frame construction including portal-like individual components that are stabilized with longitudinal reinforcements, and movable unit formed as chassis construction

摘要

The device (1) has a movable unit (2), and a stationary unit (3) accommodating the movable unit in a retaining chamber that includes a frame construction that is covered using a covering. The movable unit is guided within the frame construction in a driving direction using a guiding unit that is anchored in a base. The frame construction has consecutively arranged portal-like individual components that are stabilized with longitudinal reinforcements. The movable unit is formed as a chassis construction that is locked at the base in a closed condition using a plugging post (5).
