Folding Hatch Cover

MacGregor ist der weltweit größte Hersteller von Lukendeckeln (Hatch Covers) mit geschätzt 50-60% Marktanteil. Folding Hatch Covers sind der Standard auf modernen Bulk-Carriern — die Panels falten sich hydraulisch übereinander und geben die gesamte Lukenöffnung frei. Wasserundurchlässigkeit ist SOLAS-kritisch: undichte Lukendeckel sind eine der Hauptursachen für Bulker-Verluste (z.B. MV Derbyshire, 1980). MacGregor/Cargotec bietet auch Side-Rolling und Pontoon-Typen.
