Ground surface access assembly
A ground surface access assembly including a cover member 12. The cover member includes a reinforcement arrangement 16 and one or more seating surfaces 18 which contact a support frame. The reinforcing arrangement may be provided as ribs and may be forked to form two fingers. The fingers may be curved 106 and may have seating surfaces 46 located at the end. Ribs may be provided along two separate axis and may include multiple forked sections. The ribs may vary in depth and width along their length so as to form thicker and thinner portions. The arrangements of the reinforcing ribs may serve to increase the strength of the cover.
