Abstract
A trailer rack assembly stores and transports vertically-oriented panels that are fragile to impacts directed upon their major planar surfaces. The trailer rack assembly includes a bottom frame for supporting the panel in a vertical position, a top frame for containing the panel while being supported on the bottom frame, and a plurality of struts interconnecting the bottom and top frames. The struts are capable of absorbing and distributing lateral forces imposed upon the top frame, the bottom frame and/or the supported panel. One or more attachment projections extend from the rearward portions of the top frame, the bottom frame and/or an interconnecting strut. The attachment projection(s) are attachable to a rear tandem assembly having wheels mounted on one or more axles, the rear tandem assembly, and to a movable front assembly, which supporting the attached trailer rack assembly above the ground surface. Imparting a longitudinal force to one or both of the front and rear assemblies correspondingly urges the trailer rack assembly in the longitudinal direction.
