    • A loader bucket orientation indicating system is provided for a bucket pivotal at an end of a loader boom. The system includes a support member having a base fixed to a side of an arm of the boom and a shaft projecting from the base. A pivot plate includes a central hub rotatably mounted on the shaft and an arm projecting outwardly from the central hub. An outer end of the arm forming a visible bucket position indicator. A linkage couples the bucket to the pivot plate so that the pivot plate rotates clockwise and counter-clockwise as the bucket rotates clockwise and counter-clockwise, respectively, with respect to the boom. A rotary device has a base fixed with respect to the boom arm, and has a rotary member coupled to the base by a non-rigid coupling. The rotary member has a visible mark thereon. The position of the bucket position indicator relative to the mark provides an indication of bucket orientation.A weight attached to the rotary member maintains it in a substantially fixed orientation relative to a horizontal plane.
    • 提供了一种用于在装载机起重臂的端部枢转的铲斗的装载机铲斗定向指示系统。 该系统包括支撑构件,该支撑构件具有固定到悬臂的臂的一侧的基座和从基座突出的轴。 枢转板包括可旋转地安装在轴上的中心毂和从中心毂向外突出的臂。 臂的外端形成可见的铲斗位置指示器。 连杆将铲斗连接到枢转板,使得当铲斗相对于起重臂分别顺时针和逆时针旋转时,枢轴板顺时针和逆时针旋转。 旋转装置具有相对于悬臂臂固定的基座,并且具有通过非刚性联接件联接到基座的旋转构件。 旋转构件上具有可见标记。 铲斗位置指示器相对于标记的位置提供铲斗定向的指示。 附接到旋转构件的重物将其相对于水平面保持在基本上固定的取向。
