Every equipment type in Hatch Covers & Cargo Access links to full manufacturer and model data, specifications and service notes.

Folding Hatch Cover
A folding hatch cover splits into hinged panels that fold upward in pairs and stack clear of the opening, trading the wide-open access of a rolling or lift-away cover for a mechanism that needs no separate stowage space on deck.
426 models
Side-Rolling Hatch Cover
Side-rolling covers move cargo hold panels sideways on wheeled bogies riding rails along the coaming, opening the hold in one motion without cranes, unlike pontoon covers that must be lifted clear individually.
359 models
Pontoon Hatch Cover
Pontoon covers are individual lift-off panels craned into place rather than rolled or folded, the simplest and most repairable hatch cover type but the slowest to open without shore or ship's cranes.
316 models
Piggyback Hatch Cover
A piggyback hatch cover stacks two panels at one end of the hatch instead of folding or rolling them clear, trading some hold length for a mechanism with far fewer moving parts to jam or flood.
36 models
Sliding Hatch Cover
Sliding hatch covers move horizontally on wheels along the hatch coaming, either stacking to one side or riding piggyback over an adjacent panel, and are the standard choice on container ships where deck space beside the hatch is needed for lashed containers rather than parked cover panels.
20 models
RoRo Ramp
A RoRo ramp carries wheeled cargo on and off the ship under its own power, unlike a hatch cover that seals a hold from above. It doubles as a closing appliance against flooding when stowed, which puts it under a stricter watch than ordinary cargo access equipment.
19 models
Ramp (Stern/Side)
A RoRo ramp is a structural bridge, not a hatch — it has to carry rolling cargo at full axle load while sealing the same opening watertight when stowed, and the two jobs pull the design in opposite directions.

Knowledge

What a Hatch Covers & Cargo Access engineer checks first.

A side-rolling hatch cover is made up of individual steel panels that ride on wheels along a rail track fitted to the top of the hatch coaming, opening by travelling sideways to stack clear of the opening at one or both sides. That differs from a folding cover, whose panels hinge upward and telescope on top of each other, and from a piggyback cover, whose panels stack lengthwise on rails running fore and aft. The side-rolling arrangement suits hatches that are wide relative to their length, where there is no…
