Abstract: A support for a trolley, having a running surface that is formed on the support for the trolley, an upper chord, a lower chord and braces that connect said chords together, wherein the braces are designed to be flat, and each brace has a main surface that faces away from the support longitudinally between the upper chord and the lower chord. Two of the braces form a brace pair in each case and are arranged next to one another as viewed in the direction of the longitudinal axis of the support, preferably on the outside of opposite longitudinal sides of the support. To provide such a support, the flat braces are releasably secured to the upper chord and/or to the lower chord. The invention also relates to an overhead transport device having such a support and a trolley that can be moved along the support on the running surface.
