摘要： An anchor spreader having a frame which mounts a head assembly for vertical movement between a raised travel position and a lowered operative position and with the head assembly having spreader members which can be positioned immediately above a tie and inwardly of portions of rail-mounted anchors extending above the tie. The spreader members can be moved apart to shift the rail-mounted anchors along the rail away from the tie to achieve the anchor spreading. Positive clamp structure securely holds the head assembly in position longitudinally of the rail whereby the head assembly can remain in fixed position regardless of the reaction to forces exerted in spreading one or more rail mounted anchors.
摘要翻译：一种具有框架的锚固扩张器，该框架安装用于在升高的行进位置和降低的操作位置之间垂直运动的头部组件，并且所述头部组件具有吊架构件，所述吊架构件可以被定位在紧固件的上方并且向内延伸到轨道安装的锚的部分领带上方吊架构件可以分开移动，从而将轨道安装的锚固件沿着轨道远离绑带以实现锚固扩展。正夹具结构将头部组件牢固地保持在轨道纵向的位置，由此头部组件可以保持在固定位置，而不管对扩展一个或多个轨道安装的锚定件施加的力的反应。
