Vertical positioner THZL

rotary2-axisfor robots

Overview
THZL is a series of 2-axis robotic positioners engineered for high-precision welding and automation. Each unit provides one horizontal and one vertical axis and features a sliding tailstock to adapt to different workpiece lengths. The series supports a wide capacity range and multiple drive configurations for integration with industrial robot cells.

Key properties

• 2-axis configuration: 1 horizontal + 1 vertical
• Sliding tailstock for adjustable workpiece support
• Multiple size options: capacity range 1,000–40,000 kg
• Single or double drive configurations (SD / DD)
• Options for solid (SSH) or hollow (HSH) shaft
• Designed for integration with major robot brands
