Abstract

To permit attachment of a suspended track without drilling of holes lfor installation and connection to support elements (25), the track has an upper hollow structural section (2), for example in essentially semi-circular shape with depending vertical sections (10), a similar lower hollow structural section (2) joined by a connecting web (3), the sections in the web are unitary, the web being of generally horizontal C-shape in cross section, with a generally vertical back portion (11), mutually converging or approaching forward portions (5) which are bent over themselves to form diverging wing portions (6) leaving a groove-like gap (4) therebetween, the ends (7) of the portions (5) and the diverging wing portions (6). Hanger elements (25) can be longitudinally positioned by clamping the hanger elements against internally positioned clamping bars or plates (27), permitting longitudinal alignment by relative sliding of the clamping bars within the C-shaped chamber. Electrical connection bus ways and the like can be applied at the side opposite the gap by snap clips (22) snapped over the web (3) where it is rounded to form the C-shape.

Dependent claims

Suspended track for monorail suspended trolleys having

an upper hollow structural section (1);
a lower hollow structural sections (2);
and a connecting web (3) connecting said upper and lower sections together, adapted to be supported by hanger elements (25) laterally attachable to said web, and further being adapted to support electrical connection tracks, buses or rails (15),
said connecting web being a unitary element integral with the upper and lower hollow structural section and defining a central portion, and mutually approaching end portions leaving, between the ends (8) thereof, an open space;
and wherein, in accordance with the invention,
the central portion of the generally C-cross-sectionally shaped connecting web forms a back portion (11);
the end portions of said web extend forwardly from the back portion, converging towards each other and leaving, between the ends (8) thereof, a groove-like open gap (4) which defines said space;
and mutually diverging wing portions (6) are provided extending upwardly and downwardly away from said gap (4), said wing portions merging into said upper and lower hollow structural sections (1, 2) and extending to form upper and lower hollow structural portions, respectively, of said sections.
