Definitions

  • the attach- [58] Field of Search 104/93-95, ment of the tracks to the rail is such that a certain 104/ 106-109, 111, 118, 120, 89, 110, 119, clearance is respectively obtained between the up- 121; /141, 144, 148, 150, l52-155, 145, wardly facing surfaces of the upper lip and the means 146, 147 used to attach the tracks to the rail.
  • Tracks are known in which the carrier rail comprises two supporting sections upon each of which there is attached a rolling track independent of the rail and extended laterally in the form of a substantially vertical, upper lip.
  • these tracks in the form they have taken thus far, do not overcome the aforesaid drawbacks.
  • An object of the present invention is to provide an improvement in the tracks of overhead railways systems, of the kind hereinbefore described, which at least substantially overcomes the said drawbacks.
  • the invention consists in an overhead railway having a rail comprising two supporting sections each having attached thereto an elongate track, wherein the tracks have located along the longitudinally extending edges thereof elongate lips which extend substantially perpendicular to the long axes of the tracks and wherein attachment means are provided for attaching said tracks to said sections in a manner to provide a clearance between one edge surface of re spective lips and an opposing surface of respective ones of said attachment means.
  • each of the rolling tracks in its position of use, is extended laterally by a substantially vertical bottom lip, said lip is integral with the rolling track and constitutes a folded portion thereof, said bottom folded portion being in contact with the edge of the corresponding supporting portion of the rail.
  • the supporting rail and the rolling tracks are constituted respectively by sequentially arranged rail and track elements
  • the joints between the rolling track elements are, preferentially, staggered in relation to those between the rail elements.
  • FIG. 1 is a transverse sectional view of the overhead railway
  • FIG. 2 is a longitudinal section taken on the line ll-II of FIG. 1.
  • the overhead railway comprises a supporting rail 1 formed by two substantially vertical sections Ia each of which, at its bottom end, has a horizontal inwardly extending portion lb, the two sections being connected to one another by a box section member lc.
  • An independent rolling track 2 preferably of drawn alloy steel with a high elastic limit, is attached to each of the portions 112, which constitutes a supporting section for the track with the illustrated embodiment.
  • track in cross section, has a generally S-shaped form, that of its part in contact with the section portion lb being extended, at one of its ends, in the form of a fold 2a which is intended to contact the end of the portion 1b, and is extended at its other end in the form of a fold 2b, which is intended to be applied against the corresponding section portion la.
  • the attachment of the track 2 to the supporting rail 1 is effected, at spaced locations, by keys 3 which contain a milled groove in which there fits with a certain degree of clearance the fold 2b of a track, the keys being attached to the sections 1b by bolts 4 so that the folds 2b of the tracks are maintained in contact with said sections.
  • the supporting rail 1 and the rolling tracks 2 respectively comprise sequentially arranged rail elements and section elements; the joints between the track elements 2 are staggered in relation to those between the rail elements.
  • An overhead railway structure for suspended load carrying devices having a rail comprising two supporting sections each having attached thereto an elongate track, wherein the tracks have located along the longitudinally extending edges thereof elongate lips which extend substantially perpendicular to the longitudinal axes of the tracks and wherein attachment means are provided for attaching said tracks to said sections in a manner to provide a clearance between one edge surface of respective lips and an opposing surface of respective ones of said attachment means.
  • each of said tracks has two lips formed such that, in cross-section, said track has a generally S-shaped configuration.
  • each of said tracks has two lips formed such that, in cross-section, said trackhas a generally S-shaped configuration.
  • sections and the tracks comprise respectively section elements and track elements arranged one after the other in superposed relationship; and wherein the joints between track elements are staggered in relation to those between respective section elements.
