摘要： A dipper handle includes a dipper tube, a dipper engagement member, and an intermediate member between the dipper tube and the dipper engagement member. The dipper tube has a substantially cylindrical outer surface and a contoured inner surface. The contoured inner surface results in multiple wall thicknesses for the dipper tube, including a first thickness proximate a first end and a second, larger thickness, proximate a second end. The second end is configured for coupling to the intermediate member.

摘要： A boom uses formed plates instead of a round pipes for the chords of the boom. Each formed plate provides a flat surface for attaching lacings so that complex coping cuts required for round pipe chords can be eliminated. The boom also displaces lacing attachment points so that overlapping welds in previous boom assemblies are also eliminated. The open back of the formed plate and non-overlapping lacing attachment points eliminate hidden welds and obscured mounting surfaces that make inspections and repairs of current boom assemblies difficult or impossible.

摘要翻译： 吊杆使用成形板而不是用于吊杆和弦的圆形管。 每个形成的板提供一个平坦的表面用于附着漆，以便可以消除圆管和弦所需的复杂的对应切割。 起重臂还可以取代系带连接点，从而也消除了以前起重臂组件中的重叠焊缝。 形成的板和非重叠的鞋带附接点的开放背部消除了隐藏的焊缝和遮蔽的安装表面，使得当前悬臂组件的检查和修理变得困难或不可能。
