Apparatus for continuously monitoring height of upper edge of slide of road or highway with respect to floor plane, has display device including visual upper and lower limits to visualize needle to determine height of upper edge of slide

摘要

The apparatus has a pantograph-type supporting structure (SP) articulated in rotation about an axis perpendicular to a floor plane (PC). A scanning carriage (C) is attached to the supporting structure for circulating the carriage on a lower edge (AI) of a slide (G). A needle is carried by an upright in a plane of the bearing structure, where the needle is positioned in a fixed angular position. A display device includes visual upper and lower limits to visualize the needle to determine height of an upper edge (AS) of the slide at the point of contact of the slide with rollers of the carriage.
