Semi-trailer shipping support structure

摘要

A sheet supporting rack has (1) a base including a pair of spaced elongated runners detachably secured on flatbed of a trailer; (2) a back support including a strut mounted on each of the runners; and (3) a front restraint including an upright slidably mounted on each of the runners. The sheets are mounted in a generally vertical position with an edge of the sheet supported on the base, and a major surface of the sheets supported by the back support. The uprights of the front restraint are slid and angled with respect to the runners to urge the sheets against the back support and to secure the uprights in position on the runners to prevent movement of the sheets during shipment thereof.
