Reducer inserts are mounted into the basic clamping tools in order to apply different pipe dimensions. The optional basic frame is equipped with precise linear guidings for an exact and easy movement of the basic clamping tools. For an easy on-site fabrication of segmented bends it is possible to swivel the basic clamping tools from 7.5° up to 15° on each side. The solid high performance hydraulic system is hung up in fast changeable devices and can be used with all sizes. Optional supplementary hydraulic systems increase a comfortable application and can also be used universally with all models.
