摘要： The temporary rail bridge (20) of the illustrated embodiment includes a bridge number (20) that is coupled to a track rail (16) by screw clamps (24). Each of the screw clamps (24) includes an internal tensioning component such as a spring (58) that allows for fast installation of the rail bridge (20) and maintains continuous pressure engagement in operation. The rail bridge (20) reduces track closure time due to rail damage and associated costs and inconvenience.

摘要： A rail cap for spanning a gap between two longitudinally adjacent rail sections. The rail cap includes a downwardly opening channel member mountable over the top of the rail sections across the gap. A lower clamping member is insertable beneath each rail section and securable to the channel member. A lateral restraint is provided for preventing the channel from moving toward the inside of the track. A longitudinal restraint is provided which interacts with the channel member and the ends of the gap between the rail sections to prevent longitudinal movement of the rail cap. A guide block is provided along an outer leg of the channel member to guide an inner flange of a wheel away from an inner leg of the channel member.
摘要翻译：用于跨越两个纵向相邻轨道部分之间的间隙的轨道盖。导轨盖包括一个向下开口的通道构件，该通道可安装在穿过间隙的导轨段的顶部上。下夹紧构件可插入每个轨道部分下方并可固定到通道构件。提供横向约束以防止通道朝向轨道的内部移动。提供了纵向约束，其与通道构件和轨道部分之间的间隙的端部相互作用以防止轨道盖的纵向移动。引导块沿着通道构件的外腿设置，以将轮的内凸缘引导离开通道构件的内腿。
