Abstract
A rail pulling system for efficiently drawing the ends of two rails together. The rail pulling system includes an elongate frame, a control unit, a first sliding unit and a second sliding unit, a pair of first actuators attached to the first sliding unit, a pair of second actuators attached to the second sliding unit, a plurality of third actuators attached to the frame, a pair of first engaging cams rotatably attached to the first sliding unit, and a pair of second engaging cams rotatably attached to the second sliding unit. The cams are rotated to engage a first rail and a second rail respectively by actuating the first actuators and the second actuators thereby causing an engaging portion of the cams to engage pillow blocks on the third actuators. The third actuators then draw the first sliding unit and the second sliding unit together thereby drawing the rails together.
