Support arrangement for bridge on movable beam - has rotary bearing of concave and convex ball races, connected to bridge and beam

摘要

The arrangement has a rotary bearing, which permits turning about a vertical axis. It supports a bridge on a movable beam. The bearing (4,5) is formed as a ball race connection with a convex and a concave ball race. The lower convex race is connected to the movable beam (1), the upper concave race is connected to a connection device (7) to the bridge (13). The connection device is formed as a transverse strut, the ends of which are carry two transverse side bars (11) with support rollers (11). The bars are held pivoted about a horizontal axis. The bridge supports itself on the rollers via a rail (15) on its underside. The side bars also have side guide rollers (17) for the bridge. USE/ADVANTAGE - Economical support arrangement for bridge, easy repairs/replacements, simple, maintenance-free construction.
