Single-axis U-shaped positioners

The U1 series single-axis positioners are welding positioning units with ±360° rotation, designed to place workpieces in an optimal welding position. Load capacity: 250–3000 kg. Eight models are available, featuring two frame sizes—1800×800 mm, 2500×800 mm, and 3000×800 mm—depending on the load capacity. The height of the unit from the axis center to the base is 650 mm (for smaller models) or 950 mm (for larger models).
