    Abstract: A hatch cover arrangement comprising cover sections directly hinged together in series and adapted to be pivoted from an active horizontal position above a hatch coaming bounding a hatch opening to an inactive, upwardly swung, vertical position at least partially outside the opening. A cover lifting device is arranged in opposite relation on each exposed longitudinal side of the cover and comprises two lifting cylinders each hinged at one end to a respective one of two adjacent cover sections and at the opposite end to a common hinge arm construction itself separately hinged to these sections. A wheel of the device is mounted for the support of the hinge arm construction between the latter and the longitudinal side of the cover at the junction between the adjacent cover sections. Pivoting of the cover sections to and from the inactive and active positions is accompanied by the rotation of the wheels of the two devices along longitudinal guides towards and away from one end of the hatch coaming. The main portion of each cover lifting device is arranged laterally outside the guide of the wheel thereof and the locations at which the lifting cylinders are hinged to their hinge arm construction are below the level of the guide.

    Abstract translation: 一种舱口盖装置，其包括直接铰接在一起的盖部分，并且适于从舱盖开口的舱口盖上方的活动水平位置枢转，至少部分地位于开口外部的无向上，向上摆动的垂直位置。 盖提升装置在盖的每个暴露的纵向侧面上以相对的关系布置，并且包括两个提升缸，每个提升缸的一端铰接到两个相邻的盖部分中的相应的一个，并且在相对的一端与共同的铰链臂结构本身分开铰接 到这些部分。 安装该装置的车轮以在相邻的盖部分之间的连接处在铰链臂结构的支撑件与盖的纵向侧之间被支撑。 将盖部分从非活动位置和活动位置枢转伴随着两个装置的轮子沿着纵向引导件朝向和远离舱口围板的一端的旋转。 每个盖提升装置的主要部分布置在其轮的引导件的横向外侧，并且提升缸铰接到其铰链臂构造的位置低于引导件的水平面。
