Abstract: A heavy load conveyor system (10) according to the present invention includes substantially horizontal support member (14) having a working surface (12), a plurality of substantially vertical legs (18 and 20), a base (22 and 24) and a plurality of links (26 and 28) pivotally connected at one end to the legs and at the other end to the base. A removable link brace includes a fixed member (38) and a removable member (40) having a lever member (42) and a link engaging member (46). A carriage (50) is supported by wheels (58) on tracks (54 and 56) which are substantially parallel to the plane of motion of the links and includes a plurality of rollers (60) which are substantially parallel to the tracks.

Abstract: A method and apparatus for attaching mounting plates (12 and 14) to a workpiece such as a strut (16) is disclosed. First and second conveyors (34 and 36) carry the mounting plates with the workpiece positioned above them past first and second rollers (40 and 42) respectively. The rollers have ribs which form circumferential grooves aligned to allow passage of rows of prongs (18) while the ribs extend sufficiently close to the conveyors to make contact with the workpiece and to force rows of holes 24 in the workpiece down over the prongs.
