breaking performances. Customers are therefore full of praise, especially about the much shorter cycle times, more advantageous use of energy and substantially lower costs for maintenance in comparison with traditional hydraulic press brakes. Based on this extensive practical experience, SAFAN has effectively adapted the technology and construction to the segment involving weights up to 200 tons and work lengths up to 4 metres. In addition, a strong point of the construction is the level foundation.

Servo-electronic bending with an E for even bending Without crowning you obtain the most accurate and constant bending angle along the full working length of the machine. The unique, patented roller drive system in the upper beam ensures a uniform and even distribution of forces. A balanced combination of powerful electro-motors, fixed and movable rollers and specially developed belts facilitate capacities of up to 200T. The flexible belts, which are only 3 mm thick and 100 mm wide, are reinforced with steel wires and coated with hard polyurethane. This advanced technology has been extensively tested in the demanding elevator industry. So reliable is the technology that SAFAN are able to offer a 5 year warranty on the mechanical drive system, when combined with an annual service contract. The special construction of the SAFAN E-Brake also contributes to the even absorption of large forces.

Roller drive with 4 servo motors

The O-frame acts as a single unit and deformation is kept to an absolute minimum. It is more stable, stronger and produces less deformation than a conventional C-frame.

Since the introduction in 1995, the SAFAN E-controls have been the international standard for ease of operation. The Safan touch screen concept is therefore the most functional and intuitive ManMachine interface in the sheet-metal working industry.

Turn-key delivery of automated bending solutions In 1988, SAFAN had already installed the first robotic press brake in Europe. Safan is now an experienced specialist in the field of automated bending cells including the standard SAFAN R-Brake. The SAFAN integral solutions for your production process go much further than stand-alone solutions.
