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： 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： To permit below-dock level end-loading operations and to limit accidental freefalling of a dock leveler's deck, a dock leveler includes a unique support mechanism that employs one or more safety legs with an integral or operatively connected lip deflector. The support mechanism can be selectively moved to a deck-supporting position for freefall protection or moved to a lip-deflecting position for below dock level end-loading operations. In the deck-supporting position, the safety leg prevents the deck from falling an unsafe distance. In the lip-deflecting position, the lip deflector guides the descending motion of the dock leveler's lip extension plate so that the lip, while hanging pendant, can bypass and descend below a set of lip keepers.
摘要翻译：为了允许码头下端的装卸作业，并限制码头平整机甲板的意外自由下落，码头调平器包括一个独特的支撑机构，其采用一个或多个安全腿与整体的或可操作地连接的唇部偏转器。支撑机构可以选择性地移动到用于自由落体保护的甲板支撑位置或者移动到唇部偏转位置以用于低于码头水平的最终装载操作。在甲板支撑位置，安全腿防止甲板落下不安全的距离。在唇部偏转位置，唇部偏转器引导平台矫正器的唇缘延伸板的下降运动，使得唇缘在悬挂吊坠时可以绕过并下降到一组嘴唇保持器之下。
