Abstract
A cover for an elongated and relatively narrow tank or channel is formed from a series of panels arranged in parallel, edge-to-edge fashion, each panel spanning across the channel and resting on rims of the channel. Each panel is formed of a large plurality of side-by-side, preferably edge-connected deck slats having lengths extending in the longitudinal direction of the channel. At junctions between adjacent panels, structural transverse members have deck slat receiving channels for engaging with and supporting ends of the deck slats. In preferred embodiments the transverse structural members are generally L-shaped, with the L-shaped structural member of one channel nesting into the L-shaped structural channel of an adjacent panel, providing for removal of alternate panels by lifting. Deck slats include special handle slats for inclusion near the two transverse ends of the removable panels to enable lifting of the panels for access to the tank or channel. All of the connections between planks, structural members and other components preferably are made without welds, and sealing gaskets are provided for establishing a substantially gas tight seal.
