ABSTRACT:
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.
