摘要： The lift boom is of a generally T-shaped configuration, the stem of the T-boom being provided with a hook to which any suitable load may be attached. The head of the T-boom is seated within a front loader tractor''s bucket in the floor/rear wall corner. An upper cable is attached at one end adjacent the hook end of the boom''s stem, and is passed over the bucket''s top edge and attached at the other end to the bucket. A lower cable is attached at one end to the boom''s stem intermediate the ends thereof, and is passed beneath the bucket''s floor and also attached at the other end to the bucket. The lower cable is provided with a turnbuckle assembly. The turnbuckle assembly is adjustable when the boom is seated in the bucket to provide a suitable tension on both the upper and the lower cables, thereby maintaining the T-boom in the initial assembled relation with the bucket no matter what the spatial orientation of the bucket (and, hence, the boom) as set by the tractor, and no matter what the load being carried by the boom.

摘要翻译： 提升起重臂具有大致T形的构造，T型起重臂的杆杆设置有可以附接任何合适的载荷的钩。 T型臂的头部位于前装载拖拉机的铲斗中的地板/后墙角落中。 上部电缆在与吊杆杆的钩端相邻的一端处附接，并且通过铲斗的顶部边缘并且在另一端附接到铲斗。 下端缆线一端连接到悬臂杆的中心部分，并在铲斗底部通过，另一端连接在铲斗上。 下部电缆设有螺丝扣组件。 当吊杆位于铲斗中时，螺丝扣组件是可调节的，以在上部和下部电缆两者上提供合适的张力，从而将T型起重臂保持在与铲斗的初始组装关系中，而不管铲斗的空间取向如何 （以及因此是起重臂），而不管起重臂承载的载荷如何。
