Roller positioner RWD 260

 

Necesary choice

The green color indicates an element or the part that have to be installed to the machine in one of the offered variants already during its production and the machine cannot be forward into the operation without it, or order it.

 

Construction surcharge

Yellow coloring means an element or the part which have to be installed into the machine in some of the offered variants already during its production. In principle it is a device extending functionality.

 

Free equipment

The gray coloration indicates an element or the part which is possible to fit the machine at any time later. Assembly is possible by the end user. In principle it is an equipment which expands functionality.

Machine is suitable for working in the industry in the mode 7/24. The sophisticated design of the positioner brings significant advantages and perfect variability for welding and handling of containers and round products. High-quality drives guarantee the unit's excellent dynamic properties under full load and in conjunction with the NEXT unit.

 

 

  • RWD 260 EASY is a self-adjustable roller positioner - working unit with the possibility of adjusting the roller gauge. The concept is a sophisticated device of high design standard, using only first-class components.

  • The steel frame structure supports tilting laterally movable support units with integrated asynchronous drives. The support units are compact in design and their lateral position is fixed by a simple pinning system. If the positioner is operated on a track, the machine can be equipped with an ingenious pneumatic positioner lifting system, which allows the positioner to roll comfortably on the track.

  • The support units can be fitted with rollers with vulcanized rubber surface or CrNi steel surface. The design variation allows the choice of four, eight or twelve rollers. This makes it possible to achieve a minimum specific pressure on the vessel surface and thus eliminate the risk of deformation of the vessel shell. The system of transverse gauge adjustment together with the automatic tilting of the support units guarantees a perfect centric distribution of the pressure forces induced by the weight of the vessel.

  • The positioner is equipped with analog hand controler with the functionality of rotation speed adjustment. Optionally, a motor brake can be installed to prevent the positioners from spinning during eccentric loading.

  • The machine is suitable for MIG/MAG and TIG welding, including pulsed arc welding and plasma beam welding.

      

  


 

Main benefits

√  Two step synchronized motors and gearbox of highest quality provide great dynamics and efficiency of the drive.

 Minimalization of specific pressure on the surface of the cylinder quaranteed by self – adjustable carring units

 Precise eccentric division of pressure powers caused by weigh of the cylinder thanks to adjustable wheelbase of carring units

 Resistant industry design without risks of  demage which could be caused by manipulation with burdens.
