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。

摘要： adapted to be disposed in a pit is disclosed. A hinge member with a hinge pin receiving area and a hinge pin disposed in the hinge member defines a center of rotation. A deck that is rotatable about the hinge pin includes a curved portion with a constant radius and a center of curvature substantially similar to the center of the hinge pin. The curved portion defines an elevation that remains constant as the deck rotates about the hinge pin.

摘要： A dock leveler for a truck loading dock includes a pivotal deck that is actuated by an inflatable column assembly. The inflatable column assembly includes a pliable tube that when inflated has a generally vertical cylindrical shape that can provide a heavy deck with substantial columnar support. The shape and orientation of the column assembly is such that the lengths of the pliable tube's seams are minimized. A pliable fabric sheet held in tension against the underside of the deck provides a generally flat, broad surface against which the pliable tube can push as the inflatable column assembly pushes the deck upward. A footed pallet underneath the pliable tube can be banded to the deck during shipment. After installation, the pallet can be readily lifted for cleaning the pit floor underneath the pallet.
