Abstract

En brunnsbetäckning innefattar en betäckningsring (1) och ett med hjälp av en skruv- och mutter-mekanism (15; 22) lyft- och sänkbart lock (2). En skruv (22) är vridbart lagrad och axiellt förankrad i en från lockets undersida nedhängande gjutgodskropp (45) med hjälp av en segmenterad spårryttare (39) och en spårryttarens delar sammanhållande hållar-ring (41).A well cover comprises a cover ring (1) and a lifting and lowering lid (2) which can be lifted and lowered by means of a screw and nut mechanism (15; 22). A screw (22) is rotatably mounted and axially anchored in a casting body (45) hanging from the underside of the cover by means of a segmented groove rider (39) and a retaining ring (41) holding the parts of a groove rider.
