The RT-103 Rail Threader is used by rail gangs to lay or remove continuous welded rail. The heavy-duty construction allows the Threader to grab the rail in any position, roll the rail upright and thread the rail directly onto the tie plates. The RT-103 keeps the rail low to the ground, which significantly helps to control the rail laying or rail removing process. The RT-103 is supplied with a rail safe lock that prevents the Rail Threader from opening once the Rail Threader is locked on the rail. Four rollers are attached to a pair of self-aligning pivot bars that always maintain contact with the underside of the ball of the rail when handling rail.
