3100×30 mm - 4 hydraulic cylinders

CRONOSSTECH SHSB 4R 30-400

STANDARD EQUIPMENT
* The bottom, top, and side rolls move linearly up and down via hydraulic cylinders connected to the frame
* Protected against overload
* Top and side rolls are driven by hydromotor and planetary gearbox (3-roll motor drive)
* The positions of the rolls can be easily read via three digital displays
* Thanks to a hydraulically opening head and an automatically lifting shaft, bent workpieces can be easily removed
