ProStar™ Press Brake PRSBO6778NC

BP/NC Series Heavyweight Press Brake

Praxair’s ProStar™ PRSBP6778NC hydraulic press brake is bigger and heavier than the PRSBP5060NC, with productivity features such as additional fine adjustments for extreme production accuracy, 50 percent more horsepower and a 35-gallon oil reservoir.

Due to larger size and more than 60 tons of capacity, this hydraulic press brake comes standard with a hydraulic auto-crowning compensation system that ensures straight bends, even while working at full capacity. Upper beam and auto-crowning compensation devices have separate, scaled pressure regulators.

Six sensor safety curtains, 6.29-inch table width, front material rests and one set of multi-vee tooling are included.
