Rotary positioner THZ

vertical2-axisfor robots

Overview
THZ is a 2-axis robotic positioner (1 horizontal + 1 vertical axis) designed for synchronized robot and workpiece movement in complex welding operations. Available in multiple sizes to handle workpieces from 1,000 kg up to 40,000 kg.

Key properties

• Infinite rotational capability on the rotary axis
• High-precision positioning for multi-axis welding

Application
Designed for welding cells where synchronous movement between robot and positioner is required, enabling coordinated motion paths for complex geometries and multi-pass welding processes.
