1. Introduction

 

This series is lead-screw adjustable type. Our welding roller beds designed for maximum workpiece loads from 2T to 40T 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.
