1. Introduction

 

This series is bolt adjustable type. It also can take self-alignment/self-centering rack. Our welding roller beds is designed for maximum workpiece loads from 2T to 250T 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.
