Self Aligning Rotators with Siemens Inverter and Electric Controls

Quick Detail

• The self- align/adjusting rotator is suitable for circular pipe/tank/vessel welding;
• The distance between wheels can be adjustable by it self.
• Single motor drive system;
• 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;

1. Introduction

This series pipe welding rotators are self-alignment/self centering type.

Our welding roller beds designed for maximum workpiece loads is 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 pipe welding rotator according to your special requirements.
