Abstract
An overhead guard assembly for use on an materials handling vehicle provides the operator with protection against falling objects. The assembly includes first and second frame members supported by the vehicle and positioned on either side of the operator, and a plate member placed between and secured to the frame members over the head of the operator. A plurality of openings are formed in the plate member to provide the operator a clear view upwardly through said overhead guard. The openings in said overhead guard are arranged in rows and a plurality of strengthening ribs are placed in the plate member between the rows and extend from one frame member to the other. The strengthening ribs are formed by reverse bending the plate member to provide a rib surface orientated at an angle of approximately 50.degree. with respect to the horizontal to provide minimum visual obstruction to the operator.
