摘要 |
The manhole closing device comprises a frame (4) and a cover (6) articulated to the frame around a first axis (X-X) by means of a hinge (14). There is a locking means (16) which holds the cover open in a first position and an unlocked second position where the cover can be pivoted around the axis. The hinge is designed so that the cover while resting on the frame can pivot around a second horizontal axis (Y-Y). |
