Abstract

A hatch cover including a multiplicity of relatively narrow cover panels of L-shaped cross-section which are laid over a hatch coaming having a panel storing station at one end thereof, with their longer legs placed side by side horizontally thereon and with their shorter legs depending as skirt portions in hatch closing position. A scooping support carriage is provided for supporting the weight of all cover panels loaded thereon in superposed manner while scooping up one panel after the other progressively during a movement of the carriage so as to bring them from a hatch closing position to a panel storing position during hatch opening operation, and vice versa. The carriage is provided with cam means for actuating push rod members slidably mounted on each cover panel upwardly so as to elevate an adjoining cover panel at a level higher than that of the former panel as a first move for bringing the latter panel into superposed condition over the former panel, in addition to another cam means for holding all of the cover panels loaded thereon in superposed condition one above the other.
