    • An automatic three-speed winch comprising a base plate (1), a bollard (2) mounted for rotation relative to said base plate and carrying teeth (7) on its inner surface, arranged to cooperate through intermediate gears, with at least one driving gear (5, 6) around a central shaft (14) of the winch. An element (21, 22) is provided, which is mounted for rotation between a first and a second position about the central shaft (4) of the winch, which element carries three shafts (12, 14, 20), with a pair of gears (8, 11; 18, 19; 10, 13) being mounted for rotation about each shaft. The transition between the three different speeds takes place fully automatically by just changing the direction of rotation of the driving gear, without requiring any further operation on the winch.
    • 一种自动三速绞盘,包括基板(1),安装成相对于所述基板旋转的支柱(2),并在其内表面上承载齿(7),其布置成通过中间齿轮协作,具有至少一个驱动 围绕绞盘的中心轴(14)的齿轮(5,6)。 提供了一个元件(21,22),其安装成围绕绞盘的中心轴(4)在第一和第二位置之间旋转,该元件承载三个轴(12,14,20),一对 安装用于绕每个轴转动的齿轮(8,11; 18,19; 10,13)。 通过改变驱动齿轮的旋转方向,三个不同速度之间的转换完全自动进行,而不需要对绞盘进行任何进一步的操作。
