Bridge plate (mechanism)

渡板（Bridge Plate）是一种机械、可移动形式的轮椅坡道，设置于一些低地板轻轨铁路车辆供轮椅上下之用。渡板由车辆伸出至站台，同时站台高度必须升至接近车厢地板水平，令轮椅不需要通过过于陡峭的斜坡抵达车门（美国残疾人法案规定坡度不得超过每12英寸（30.48厘米）长度上升1英寸（2.54厘米））。 一些低地板巴士亦采用渡板（在此情况下延伸至路缘）以供轮椅上下，但是许多低地板巴士使用斜板，斜板通常是地板的一部分，但可以借助门口铰链翻出并放置在路缘或路面上；在此情况下斜板可以替代渡板作为轮椅坡道，同时避免过于陡峭的坡度。 渡板可以由车辆操作员或其他工作人员手动放置，亦可是带动力的可伸缩坡道形式。 北美首先配备可伸缩渡板的铁路车辆是俄勒冈州波特兰的西门子SD660轻轨列车， 首列出厂于1996年。早些时候，1987年开业的萨克拉门托轻轨系统，在每个站台设有一段加高部分，配合固定在站台的手动渡板，覆盖高站台和列车地板之间的空隙。

A bridge plate, or bridgeplate, is a mechanical, movable form of wheelchair ramp that is used on some low-floor light rail vehicles (LRVs) to provide for wheelchair access. The bridge plate extends from the vehicle to the platform, which must be raised to close to the level of the floor of the vehicle so that the wheelchair need not travel over an excessively steep ramp (in the United States, the Americans with Disabilities Act specifies that the slope must be no more than 1 inch of rise for every 12 inches of length). Some low-floor buses also use bridge plates (in this case, extending to the curb) to provide for wheelchair access, but many low-floor buses instead use a ramp that normally serves as part of the floor but can be flipped out through the door (using a hinge at the door) onto

The bridge plate extends from the vehicle to the platform, which must be raised to close to the level of the floor of the vehicle so that the wheelchair need not travel over an excessively steep ramp (in the United States, the Americans with Disabilities Act specifies that the slope must be no more than 1 inch of rise for every 12 inches of length). Some low-floor buses also use bridge plates (in this case, extending to the curb) to provide for wheelchair access, but many low-floor buses instead use a ramp that normally serves as part of the floor but can be flipped out through the door (using a hinge at the door) onto the curb or street; in this case the ramp is long enough that it can serve as a true wheelchair ramp rather than a bridge without being excessively steep. Bridge plates can be manually deployed (by the vehicle operator or other crew person) or powered, rectractable ramps. The first passenger rail cars in North America to be equipped with retractable bridge plates were TriMet's (Portland, Oregon) Siemens SD660 LRVs, the first of which were completed in 1996. Earlier, in 1987, the newly opened Sacramento RT Light Rail system used non-powered, station-platform-mounted bridge plates to bridge the gap between a high-platform section at each station and the floor of an LRV.
