Rail Bull | Welding & Cutting Track Carriage

Rail Bull

RAIL BULL is a track carriage designed for plate bevelling or establishing groove and fillet welds with or without oscillation using MIG/MAG welding torches. The machine can work in PA (flat), PB (horizontal vertical), PC (horizontal), PD, PE (overhead), PF (vertical up) and PG (vertical down) welding positions.


Continuous welding
Horizontal speed 0–120 cm/min
Vertical speed 0–110 cm/min
Linear oscillation
Min convex radius 5000 mm
Min concave radius 5000 mm

Key features

Rail Bull | Welding & Cutting Track Carriage
The Rail Bull is a track welding tractor designed to produce butt and fillet welds with or without oscillation. The tractor can work in PA (flat), PB (horizontal vertical), PC (horizontal), PD (overhead horizontal-vertical), PE (overhead), PF (vertical-up) and PG (vertical-down) welding positions. Rail Bull moves along either rigid or semi-flexible track on both ferromagnetic and non-ferromagnetic materials thanks to rack and pinion drive and tracks fixed to flat or curved surfaces by means of various magnetic or vacuum units. The minimum curvature radius required for semi-flexible track is 5 m (16 ft).
