A hatch cover is used to close off a ship's cargo hatches. NauticExpo offers sliding, multi-folding, piggyback and other types.
ApplicationsThese covers protect hold cargo from inclement weather. They also allow cargo to be stowed on deck, as on container ships.
TechnologiesEach of the many different types of hatch cover functions in its own way. Multi-folding covers fold back to give access to the hatch and are operated by hydraulic cylinders. Sliding hatch covers are common on bulk carriers, opening and closing laterally. A hydraulic mechanism lifts the piggyback hatch cover and places it on top of the hatch cover just fore or aft. Lift-on/lift-off hatch covers require a crane to move them.
How to chooseChoice will depend on ship and cargo type. With the exception of the lift-on/lift-off variety, all hatch covers operate via a hydraulic system requiring regular maintenance.
