Abstract

The travelling clamping beam (3) is for use on a long prestressed concrete casting bed (1) to position the moulds (2). The beam aligns transversely over and travels along the bed and has two sliding combs (5, 6). The combs are disposed about a fixed centering unit (7) are power-driven and connected by racks (8, 9) so as to maintain a symmetrical mobile relationship. The beam may be suspended (11) by the sliding combs and from a travelling elevator-gantry-crane (10-16). The comb drive may comprise beam-mounted hydraulic jacks (7) and the teeth (17) of the combs may be 'L' shaped. The clamping plates may be mounted on lateral teeth and have large extension relative to those of the arms of the primary teeth. Wedges or jacks may be used to chock the moulds after clamping.
