SAFAN H-Brake: for high precision and productivity What is immediately striking about the SAFAN H-Brake is its robust construction. This includes a large space between the side frames and a large daylight opening, enabling the machine to be put to optimum use along its entire working length.

The concept was developed in order to ensure high productivity of faultless, precision work. All machining of the large mechanical components is completed in one session, so that the machined surfaces are perfectly parallel and square. The position of the top beam is measured and controlled with the greatest accuracy. The measurement is made by two linear sensors that are installed on a robust measuring device independent of the side frame. The construction is such that the side frame assembly does not have any influence on the angle being bent.

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 that are needed when using the controls are visible on the screen. The system is so simple that it makes bending child’s play, so to speak. The controls work on a PC running under Microsoft Windows®.
