Welding and Cutting Tractor PROMOTECH RAIL TUG

Featuring a rack and pinion drive system with electronic speed control, the Rail Tug creates weld bead geometry which is exact to your specifications, reducing costly over welding and decreasing filler metal usage.
It can be used with semi-flexible tracks for plate and tank work with a minimum radius of 5 m (16 ft) or adapted to bent ring rail for pipe and tube applications. Hi-Flex tracks are suitable for variety of circumferential and irregular surface applications down to minimum radius of 750 mm (30”). Standard ring tracks are available for tube diameters from 200 mm (8”) up to 3000 mm (10 ft), whereas custom rolled tracks can be used for tube diameters between 3 m (10 ft) and 10 m (32 ft). Using a vacuum system allows the tracks to be clamped to non-ferrous surfaces (stainless steel, aluminum etc.). The Rail Tug economically meets a broad array of welding and cutting applications on flat or curved plate, tube and pipe.
