 VFD speed control Welding Rotator for Cylinder / Pipe with Double rotary Drive 80 Ton

1. Quick Details

• Steplessly controllable rotary drives by means of A.C. or D.C. motor (on request) drive via self-locking worm gear reducers;
• Schneider or Panasonic inverter to realize VFD speed control and synchronous rotation of rollers;
• Roller distance is self-aligned and roller surrounding angle among 45°～110°;

2. Introduction

This series welding rotators are self-alignment/self centering type with PU wheel.

Our welding roller beds 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 pipe welding rotator according to your special requirements.
