Abstract
A basket gate (18) mechanism, typically for use in the cargo holds (12), of bulk carriers (10), includes two opposed gate segments (50, 51) which shut along a central line. Each gate segment (50, 51) is supported at its ends by pairs of different length arms (57, 58, 59, 60), so that when the gate (18) is opened, the segments (50, 51) slope downwardly. The pairs of arms (57, 58, 59, 60) are interconnected by a small and compact direction reversing lever mechanism (61, 62, 63, 64) that ensures coordination of the movement of the segments (50, 51). The arms (57, 58, 59, 60) and the supporting framework (52) are protected by a hog back (53). The gate (18) is opened and closed by an actuating means (65), typically a double acting hydraulic cylinder, located between the gate segments (50, 51) at their midpoints, and directly acting on said said gate segments.
