1. Introduction
This series is self-alignment/self
centering type. Our welding roller beds designed for maximum workpiece loads
from 5T to 60T are used for the rotation and positioning of heavy, rotationally
symmetrical workpieces like tanks, pipes or boilers for further machining or
welding. We also provide tailor-made welding
rotator according to your special requirements.
