Abstract

The stage comprises a plurality of side-by-side, screw-operated shearlegs tables (1), each such table having its own operating mechanism (3) connected to a screw (2) and the movement of the tables being synchronized by employing electro- hydraulic step motors as the operating mechanisms. The screw (2) acts on the linkage members (5, 6, 7, 8) via transmission members (9, 10, 11, 12) and may be automatically arrested on the stopping of movement of the tables by means of a brake (4) provided on its shaft. <IMAGE>
