摘要： A dock leveler (14), for bridging the gap between a loading dock platform (10) and a vehicle (12) at the dock, includes an adjustably overlapping lip (18) and ramp (16) that provide a traffic surface of variable length to accommodate situations where there is only a limited amount of space for the lip to rest on the rear of the vehicle. The lip pivots and translates from a stored, pendant orientation to an operative orientation with a range of extended positions. In the stored position, one edge of the lip protrudes above the deck to inhibit material handling equipment from accidentally driving over the edge of the deck when a vehicle is not parked adjacent the dock leveler.

摘要： A wheel restraint for restraining a vehicle at a loading dock includes various features such as, a wheel chock supported by a spring loaded articulated arm with a spring that can be selectively tightened or released, a sensor that detects whether the chock is solidly against a base plate or floor, a bi-directional pivotal joint between the articulated arm and the wheel chock to ensure that the chock can sit squarely on a mating base plate, a wheel chock that meshes with a hydraulically actuated base plate, pivotal or otherwise movable backstops that prevent a wheel chock from sliding out of position, and a base plate cleaning system. The cleaning system might include a vehicle-actuated brush, fluid spray nozzles, electric heater and removable cover plates.

摘要： A closed loop reciprocating fluid circuit apparatus (150) for mechanically powered and electromechanically powered dock levelers (100), which may be mounted at a forward edge of a dock leveler to selectively engage the dock leveler during pivotal downward movement of a deck, is provided. The apparatus may include a header (158) extending from a fluid chamber (152) (e.g., a hydraulic cylinder), where the header may selectively engage the deck, within the range of dock leveler heights, including below dock level and above dock level operating positions. The hydraulic cylinder may be vertically oriented and coupled to a fluid accumulation chamber (156), such that vertical movement of the header in response to the deck's downward movement causes fluid displacement into the accumulation chamber. That displacement may be in a horizontally oriented fluid chamber having a piston that reacts to the fluid transfer. Alternatively, that displacement may be into a resilient fluid chamber such as a bladder (504) housed within a suitable container, or a fluid chamber (404) such as a fluid reservoir with a breather (410), for air volume compensation. The hydraulic cylinder and header may be urged to the extended position, for example by extension springs (308) acting on a piston within the fluid accumulation chamber, or by a pull chain or latch (420) coupled to the cylinder and the upward movement of the deck. A flow control valve (304), e.g., a velocity fuse or solenoid valve, is connected between the cylinder and the fluid accumulation chamber to respond to free fall of the deck. Resetting to normal operation after free fall detection may occur after load removal from the deck and by movement of the cylinder to the opposite direction or by electrical control input to the control valve.
摘要翻译：提供一种用于机械动力和机电动力平台矫直机（100）的闭环往复式流体回路装置（150），其可以安装在码头矫直机的前边缘以在甲板的枢转向下运动期间选择性地接合码头矫直机。该装置可以包括从流体室（152）（例如液压缸）延伸的集管（158），其中集管可以选择性地接合甲板，在船坞平整机高度的范围内，包括在船坞下方的水平和船坞以下经营职位液压缸可以垂直定向并联接到流体积聚室（156），使得集管的响应于甲板的向下移动的垂直运动导致流体移动到积聚室中。该位移可以在具有与流体转移反应的活塞的水平取向的流体室中。或者，该位移可以进入弹性流体室，例如容纳在合适的容器内的气囊（504）或具有用于空气体积补偿的具有通气器（410）的流体容器的流体室（404）。液压缸和集管可以被推动到延伸位置，例如通过作用在流体积聚室内的活塞上的拉伸弹簧（308）或通过联接到气缸的拉链或闩锁（420）和向上运动甲板。流量控制阀（例如速度保险丝或电磁阀）连接在气缸和液体积聚室之间以响应甲板的自由落体。自动跌落检测后重置为正常操作可能会在从甲板卸载后，并通过汽缸向相反方向移动或通过控制阀的电气控制输入而发生。
