Rail Tug|Welding and Cutting Tractor
The Rail Tug is a digitally controlled tractor designed for the mechanization of welding and thermal cutting
processes. 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.

The Rail Tug can be used with semi-flexible track 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. Standard ring rails 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 track 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.

Primary features and benefits
