A longitudinally reciprocable roller carrier useful in both a horizontal and a vertical track to support various live and dead loads which comprises a pair of juxtaposed track members of generally H-shaped cross section, a connecting track of generally I-shaped cross section located therebetween, and roller motive means connected to said connecting track and one of said track members facilitating the rollable reciprocation of said track members with respect to each other. The roller motive means comprises a plurality of strategically placed paired rollers located within the substantially enclosed track sections of the first and second track members which permit the carrier to support a continuously moving load in a cantilevered configuration.
