Piranha's mechanical linkage system provides full tonnage at any point across the ram and bed, allowing maximum flexibility for multi-operation set-ups. Operators may place full-tonnage tools anywhere on the bed. Other press brake designs require the operator to place any full-tonnage tool only in the center of the bed, resulting in added handling and lower productivity. Attempting multi-operation set-ups on other designs can result in machine damage. Other designs require more total machine tonnage for off-center applications.
Piranha's Generation II Control System, combined with the single cylinder hydraulic system, provides full control reliability in a simple, efficient design. In the event of a violation of a safety device, the dual CPU module provides two paths for signals to stop ram movement. This, with the single hydraulic valve system, provides the utmost in simplicity, maintainability, and safety.
Piranha's exclusive Preloaded Ram System (PRS) uses a dynamic system of opposing ram cylinders to preload the ram prior to movement. This system lifts the ram into the drive system, eliminating the influence of ram weight on the bending process. Furthermore, this system removes the effects of clearances and wear within the drive system throughout the life of the press brake.
Piranha utilizes a bed tilt system as opposed to ram tilt to allow for fade-out bends and to adjust for tool wear. This system allows the ram to be fully gibbed and stabilized for parallel movement. Ram tilt sytems on other designs allow for more play in the gibs and put unneeded stress on the drive system. Unlike ram tilt systems on other press brake designs, Piranha's bed tilt system easily returns to the "zero" position.
