A careful study on users’ needs, a quality oriented planning and execution have determined a product whose features and uses are:

• more compact main structure, thanks to the new design
  
• wide rotating speed regulation with Vmax/Vmin=30
  
• electronic board for a precise control of the motor speed in a.c., complete of tachometer dynamo, that keeps constant the rotation speed , even if eccentric loads cause a change in the torque factor
  
• PR100 2self-ventilated motor, granting constant rotation also at low speed
  millimetric metric ruler, parallel to the guides, allowing the reading of the position**
  
• self-holding structure in electro welded and machined steel
  
• fast and precise wheel positioning by a left and right screw. This solution allows both wheels moving simultaneously always maintaining the tank axis on the same vertical symmetry plan**
  
• all electric components are grouped in a box mounted on the base, where the main switch, the synchronizing plug for manipulators and portal, the connector for the operating board with a 5 meter cable (or a cable of any other length, at customer’s request), low tension control are located The positioners model PR and PRB are available in fixed floor version and in movable on track, with or without motor.
  
• The positioners model PR and PRB are available in fixed floor version and in movable on track, with or without motor.
