The compact, mobile type of construction enables precise and repeatable bending both stationary and directly at site or at the place of mounting, respectively. A strong motor and a precision gear cater for powerful drive. By means of position detection directly on the bending axis we achieve optimum bending accuracy. The bending angle is easily and quickly set via set/actual value display. For transport purposes, the compact unit can be neatly and safely stored in solid transport cases. At the mounting place, the tripod and the principle “stationary tube and rotating tool” enable bending with lowest possible space requirements. For thin-walled tubes slide shoes are used for wrinkle-free bending in order to produce arcs, for example from tubes made of stainless steel and copper, with smallest possible deformations. With the profile bending adaptor PB 20, flat steel bars, square steel and round bars can be bent without problems.
