H-Type-2 Three Axis Vertical Tilt Welding Positioner for 500-2000kg Parts The GBS-02-H500-2, H1000-2 and H2000-2 are three axis vertical tilt positioners for workpieces that are too heavy to turn by crane between welds. Three servo axes work together: a vertical tilt that stands the part on edge, a rotation that presents each side to the torch, and a third axis that corrects the angle of the fixture so the seam stays flat. Payload classes are 500kg, 1000kg and 2000kg,
