SAFAN E-Brake B, within everyone’s reach The second generation of SAFAN E-Brake adds important new advan tages to an already proven worldwide E-Brake technology. The machines of up to 100T are built according to a modular concept, ensuring an advance in the efficiency of machine technology. SAFAN has used this new modular concept to introduce a very competitively priced basic version on to the market, the SAFAN E-Brake B, bringing the unique E-Brake technology within everyone’s reach. The SAFAN E-Brake B is available in 4 models: 35T-1250, 50T-2050, 80T-2550
and
100T-3100.

Servo-electronic bending with an E for even bending Without crowning you obtain the most accurate and constant bending angle along the full range 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 300T.

Innovation with an E for efficiency The greatest innovation of the SAFAN E-Brake is the way in which the machines are built. Thanks to the new modular concept, the four machines in the Basic range can be produced more efficiently and delivered faster.

Ease of use with an E for ergonomic The SAFAN Touch Screen control system is the most efficient and simple Man-Machine Interface of its time. Only those buttons are visible on the screen that are needed when using the controls. The controls work on a PC running under Microsoft Windows®. Instructions are sent from the SAFAN TS
