A bearing rail system for load-bearing transfer devices which includes a pair of split rail sections that are designed and configured to engage and lock together when manipulated in a rail channel. The rail channel can be provided in a support structure which functions as a guide for a load-bearing transfer system. The split rail sections include cooperating pivotal structures which can engage one another and about which the split rail sections can be pivoted so as to expand the overall or effective base of the rail system. By positioning the split rail sections in a rail channel and pivoting them about one another, the overall or effective base can be expanded to secure the rail system in the rail channel.
