Disclosed is a conduit cart (221, 231, 241) for supporting conduits (230) above at least one rail (200). The conduit cart has a base (301); and at least two right-side protrusions, namely, a right-side sub-rail protrusion (353) extending horizontally from the base; and a right- side super-rail protrusion (351) extending horizontally from the base. The right-side sub-rail protrusion and right-side super-rail protrusion are adapted to straddle a flange of a first rail and the first rail is one among the at least one rail. Further, the base has at least two left¬ side protrusions, namely, a left-side sub-rail protrusion extending in a direction opposite to the right-side sub-rail protrusion from the base; and a left-side super-rail protrusion extending to the right-side super- rail protrusion from the base. The left-side sub-rail protrusion and left-side super-rail protrusion can straddle a substantially horizontal flange of a second rail, and the second rail is among the at least one rail. |
