The new range of MECOME roller positioners (models PR, PRB, PRX, PRT) covers a wide number of uses, such as the moving of tanks, tubes and cylinder section bodies of small, medium and large dimensions. They are usually used to support painting, assembling, cutting, circumference and longitude welding operations, and they work together with automatic plants like booms, portals etc. The PR model represents the perfect solution for the manipulation of small and large diameter tanks, since a left-right screw obtains the roll distance regulation.
Instead, the PRB model perfectly suits the manipulation of various section cylindrical bodies, since it allows automatic diameter alignment and balanced weight distribution. The weight distribution is differently obtained by the PR model if a tank of large diameter and little thickness is moved.
Technical features of PR and PRB models
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 • self-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
**only for the PR model
The positioners model PR and PRB are available in the fixed floor version and in the movable on track, with or without motor.
