ProStar ProductsroStar PRSBP6778NC Press Brake
P ™ ™
BP/NC Series Heavyweight

ProStar’s PRSBP6778NC hydraulic press brake is bigger
and heavier than the PRSBP5060NC, with productivity
features such as additional fi ne 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
machine 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.
