摘要

The cover has a rhomboid-shaped covering (1) connected with a manhole frame, and a rolling device (4) provided with an elongated slide roller at its lower side for lifting the covering. A lifting device (2) is arranged in the shaft frame and has an adjustable spring (3) that exerts a spring force on a tilting lever. The rolling device is arranged in a roller housing and has an edge bearing for insertion of a bearing shaft into a bore hole, where the bearing shaft has a locking screw.
