Abstract
Apparatus for supporting, transporting and rotating mold forms for producing concrete reinforced ties wherein a gantry includes a pair of rotatable clamping devices on opposite ends thereof whereby the mold forms may be held in a position to be filled with concrete, moved to a mold dismantling position while being rotated through an angle of 180.degree. with the concrete ties being subsequently removed from the mold forms. 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.
