Abstract

The device serves to release manhole covers from their retaining frames. It has a bearer 1 having two supporting feet 3 and a box-shaped cross section 2. A lifting spindle 12 is mounted on the bearer 1 in such a way as to be axially displaceable. The distance between the lifting spindle 12 and the supporting feet 3 as well as the distance between the supporting feet themselves is variable. A hook 17 is integrally formed on the lifting spindle 12, which is designed as a screw spindle and is accommodated by a nut rotatably mounted on the top side 6 of the bearer 1 and is rotationally locked relative to the bearer 1. <IMAGE>
