摘要： A dock leveler includes a pivotally extendable lip coupled to a pivotal deck by way of a front hinge, wherein the structure in the area of the front hinge optimizes the torsional flexibility of the deck; provides a well supported, durable crown (apex angle between an extended lip and the deck); and reduces the part count of the dock leveler. The front hinge includes a deck-hinge member that extends approximately the full width of the deck and is preferably formed from a single sheet of material. A particularly narrow front header or flange disposed along the front edge of the deck reinforces the relatively thin deck plate so that the plate's rigidity more closely matches that of the thicker lip, yet the flange is sufficiently small to allow the deck to twist so that the deck can place the tip of the lip squarely upon a sideways inclined truck bed.

摘要翻译： 码头调平器包括通过前铰链联接到枢转甲板的可枢转延伸的唇缘，其中前铰链区域中的结构优化了甲板的扭转柔性; 提供良好的支撑，耐用的冠（延伸的嘴唇和甲板之间的顶角）; 并减少了底座矫直机的零件数量。 前铰链包括甲板铰链构件，其大致延伸到甲板的整个宽度，并且优选地由单张材料形成。 沿着甲板的前边缘设置的特别窄的前集管或凸缘加强了相对薄的甲板板，使得板的刚度更接近于较厚的唇缘的刚度，但是凸缘足够小以允许甲板扭转， 甲板可以将嘴唇的正面正方形放置在侧倾斜的卡车床上。
