The rotatable clamping devices include vise means for supporting the mold forms and clamping means for holding the mold forms in their assembled condition during rotation thereof through 180.degree. while permitting dismantling of the molds after they are brought into their inverted position. The gantry device is movable over a production and dismantling area and means are provided for stacking the finished concrete ties.
