SHIELD CAP FOR A SHIELD-TYPE MINE SUPPORT

摘要

The invention relates to a shield cap for a shield-type support for underground mining, with a cap plate 2, with reception devices 4 for the connection of hydraulic cylinder heads to the shield cap and with a supporting structure 3 welded below the cap plate 2 and having a plurality of longitudinal spars. In order to simplify the outlay in manufacturing terms and to increase the bending strength, at least two of the longitudinal spars consist of I-profile struts 10 with an upper profile chord lower profile chord 11 and a middle chord 13 running perpendicularly to the two profile chords, the distance between the upper and the lower profile chord decreasing at least over a part length of the I-profile strut 10.
