The test consists in bending the bar up to 180° or to bend the same at 90° and then straighten (re-bend) if of at least 20°.The horizontal design makes specimen loading and machine operation easy. The machine is easy to operate. Beside of the main switch the hydraulic pump can be started and stopped by pressing the relevant bottoms. The manual operated valve allows to move the cylinder forward or backward by simple stir the handle in direction the cylinder shall move. The piston speed can be adjusted at the throttle valve.

The mandrels with different diameters are easy to change and the support rollers easy and stepless adjustable in accordance with relevant standard. The piston rod have some guidance to prevent horizontal/vertical buckling.

This unit is suitable for specimen diameters up to 63 mm.
The mandrels and the mandrel-holders are not included in the standard supply and have to be ordered separately.
