Roller positioner RWD 420

Machine is suitable for working in the industry in the mode 7/24. Design of the machine brings many advantages and great variability for working by the welding process and manipulation with cylinders and round cylinders as well.

• RWD 420 NEXT 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 carries the tilting laterally movable support units without 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 NEXT version is positioner with freely moving roller units, i.e. completely without drives which can be suitably combined with the driven versions RWD 420 CLEVER and RWD 420 EASY.

   

Main benefits

√  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.
