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, with the head assembly having spreader members which can be positioned adjacent a tie and inwardly a pair of rail-mounted anchors. The spreader members can be moved apart to shift the rail-mounted anchors along the rail away from the tie to spread the anchors. A positive clamp mechanism 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 anchors.
