Built for high productivity and ease of use, Praxair’s ProStar™ “supreme duty” 4-roll double-pinch plate rolls are solidly constructed to extend machine life and minimize maintenance. The PRS4RHD Series machine uses 75 percent fewer moving parts when compared with swing-arm and torsion bar plate roll designs.
Massive end frame weldments on the 4RHD Series provide superior performance, strength and rigidity. Direct linear-guide geometry delivers 100 percent thrust to the rolls, producing a better pre-bend, even to 1.1 × top roll diameter. All 3 and 4 Roll ProStar HD plate rolls are built using an identical advanced technology platform, which includes digimatic controls, antifriction guides, hydrotronic automatic digital roll balancing, plug and play socket-type wiring harness, independently-driven rollers and multiple oscillating, self-aligning tapered roller bearings.
ProStar’s PRS4RHD Series are 4 roll, double pinch, hydraulic plate bending machines. These units have independent hydraulic adjustment and inclination of both lateral bending rolls, hydraulic pinch roll adjustment with adjustable pinch pressure, hydraulic drop end for rapid part removal and independent hydraulic powered rotation of the top roll and pinch roll using high-efficiency hydraulic motors and planetary reduction units.
