Abstract
Hollow rolling element for a handling equipment comprising at least two assembled profiles forming a tubular section opened at its lower part and receiving one or several pony trucks or crane crabs, characterized in that it comprises two sheeting piles located with their concavities confronting each other on both sides of a vertical plane, the lower edges of said sheeting piles being spaced from each other in order to provide a lower elongated opening whereas the upper edges are rigidly fixed on both sides of at least one spacing member.
Claims4
In a hollow track member for a material handling installation comprising at least two elongated members defining a longitudinal slot extending longitudinally thereof and adapted to receive at least one traveller, the improvement according to which said track member comprises two identical channel-shaped sheet piles whose section comprises a central web and first and second sidewalls having the same dimensions extending along the sides of said web symmetrically with respect to a longitudinal plane of symmetry of the web, said sidewalls each carrying a flange substantially parallel to said web, said flanges being bent outwardly away from said plane of symmetry, said sheet piles being positioned with their concave surfaces facing each other, the flanges of said first sidewalls separated from each other to form said slot, and the flanges of said second sidewalls rigidly connected to each other by at least one spacer member located therebetween, said at least one spacer member having the cross-sectional shape of an inverted T, with the surfaces of the standing part of the T in contact with two flanges of the sheet piles and the arms of the cross-bar of the T in contact with the inner surface of two sidewalls of the sheet piles.
In hollow track member for a material handling installation comprising at least two elongated members defining a longitudinal slot extending longitudinally thereof and adapted to receive at least one traveller, the improvement according to which said track member comprises two identical channel-shaped sheet piles whose section comprises a central web and first and second sidewalls having the same dimensions extending along the sides of said web symmetrically with respect to a longitudinal plane of symmetry of the web, said sidewalls each carrying a flange substantially parallel to said web, said flanges being bent outwardly away from said plane of symmetry, said sheet piles being positioned with their concave surfaces facing each other, and the webs of the two sheet piles converging toward the sidewalls thereof remote from the spacer member, the flanges of said second sidewalls being rigidly connected to each other by at least one spacer member located therebetween and the surfaces of the spacer member in contact with the flanges of the two sheet piles converging in the same direction as said webs.
