摘要： A dock leveler includes a vehicle-engaging pivotal lip extending from the front end of a pivotal deck, wherein the lip has one or more unique features that provide a smooth transition for forklifts traveling between the lip and a trailer bed upon which the lip is resting. The smooth transition minimizes jolting and vibration of the forklift and its driver as the forklift wheels pass over the leading edge of the lip. The special features of the lip may include one or more of the following: a curved traffic-bearing surface terminating at a sharp or blunt leading edge, a traffic -bearing surface that includes both flat and curved sections, a multifaceted traffic-bearing surface that approximates a curved surface, a rubber or plastic shock absorbing element, an articulated nose piece at the lip's leading edge, and a main lip plate that is coplanar with the deck's traffic surface (i.e., zero crown angle).
摘要翻译：码头调平器包括从枢转甲板的前端延伸的车辆接合枢转唇缘，其中唇部具有一个或多个独特的特征，其为在唇缘和唇部休息的拖车床之间行进的叉车提供平滑过渡。当叉车通过唇缘的前缘时，平稳过渡可以最大限度地减少叉车及其驾驶员的震动和振动。唇缘的特征可以包括以下中的一个或多个：终止于尖锐或钝的前缘的弯曲的承载表面，包括平坦部分和弯曲部分的交通工具表面，多面面积的承载表面，近似于弯曲表面，橡胶或塑料冲击吸收元件，唇缘前缘处的铰接鼻片，以及与甲板的交通面共面的主唇板（即零冠角）。

摘要： A hydraulic system for operating dock levelers, vehicle restraints, and other types of loading dock equipment includes one or more features that prolong the life of the hydraulic fluid. A hydraulic reservoir with a desiccant filled breather cap or a hermetically sealed pliable reservoir minimizes the hydraulic fluid's exposure to condensation and atmospheric moisture. The system can be used for prolonging the life of both biodegradable and- non-biodegradable hydraulic fluids. In some embodiments, the system includes an acceptably biodegradable fluid having a combination of properties that makes the fluid particularly suitable for loading dock equipment.

摘要： A dock leveler (12) includes a vehicle-engaging pivotal lip (26) extending from the front end (22) of a pivotal deck (16), wherein the lip has one or more unique features that provide a smooth transition for forklifts traveling between the lip and a trailer bed (14) upon which the lip is resting. The smooth transition minimizes jolting and vibration of the forklift and its driver as the forklift wheels pass over the leading edge of the lip. The special features of the lip may include one or more of the following: a curved traffic-bearing surface (42,60,84) terminating at a sharp or blunt leading edge (34 a-g), a traffic-bearing surface (70) that includes both flat (50,72) and curved (74) sections, a multifaceted traffic-bearing surface (62) that approximates a curved surface, a rubber or plastic shock absorbing element, (78,86,114), an articulated nose piece (98) at the lip's leading edge, and a main lip plate (106,116) that is coplanar with the deck's traffic surface (36) (i.e., zero crown angle).
