Abstract
An anchor spreader apparatus and method for moving rail anchors, the anchor spreader apparatus has a mounting member, a rail clamp assembly and an anchor-engaging assembly. With the rail clamp assembly properly clamped to the rail, the anchor spreader apparatus is maintained in a proper and controlled position relative to the anchor as the anchor-engaging assembly is rotatably moved relative to the rail clamp assembly. The anchor spreader apparatus may be paired with a spike-pulling apparatus, whereby the anchor spreader apparatus and the spike-pulling apparatus simultaneously move the rail anchor and pull respective spikes.
