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).
摘要翻译：码头调平器（12）包括从枢转甲板（16）的前端（22）延伸的车辆接合枢转唇部（26），其中唇部具有一个或多个独特特征，其为在叉车唇部和一个拖车床（14），唇缘在其上休息。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（34 ag）的弯曲的承载表面（42,60,84），承载表面（70），其中包括平面（50,72）和弯曲（74）部分，近似弯曲表面的多面交通承载表面（62），橡胶或塑料冲击吸收元件（78,86,114），铰接鼻片（98））和与所述甲板的交通表面（36）共面的主唇板（106,116）（即，零冠角）。

摘要： Dock leveler safety supports are disclosed herein. An example dock leveler disclosed herein includes a deck movable relative to a platform between a raised position and a lowered cross-traffic position when the dock leveler is in a working configuration, where a first lateral edge and a second lateral edge of the deck are proximate the platform when the deck is in the lowered cross-traffic position and the deck residing at least partially in a pit when the front edge of the deck is in the lowered cross-traffic position. A front edge of the deck is above at least one of the lowered cross-traffic position or the raised position and inhibited from descending toward the lowered cross-traffic position when the dock leveler is in a service configuration. A first deck obstruction is movable relative to a deck between a secured position and an unrestrained position, where the first deck obstruction in the secured position configures the dock leveler in the service configuration and the first deck obstruction in the unrestrained position configures the dock leveler in the working configuration. The first deck obstruction extends farther beyond the outer perimeter of the deck when the first deck obstruction is in the secured position than when the first deck obstruction is in the unrestrained position.

摘要： To help hold a trailer bed (16) of a truck (12) steady at a loading dock (14) as the truck is being loaded or unloaded of its cargo, a yieldable vehi cle brace (10, 124, 144, 200, 240, 300) exerts a substantial, but limited, r eactive force upward against the trailer' s rear impact guard to resist the trailer' s downward movement. In some embodiments, the brace holds the trail er bed stationary up to a certain load limit and provides the trailer bed wi th a controlled or. dampened descent when the load exceeds that limit. In so me cases, the reactive upward force exerted by the brace increases with the downward velocity of the trailer bed. The reactive force can be created by o ne or more pressure relief valves (98), Thydraulic fluid passing through a f low restriction (236), a brake (126), a spring (2122), or various combinatio ns thereof. Some embodiments of the brace include provisions for accommodati ng horizontal movement of the rear impact guard.
