  • C.  Four independent hydraulic adjusting roller to align the two sections with each other

    D.  Large range center distance to match diffrent diameter of workpiecec

    E.  European hydraulic station, Parker oil tube and Schneider elctrical control system

    F.  Ideal for:

        - Wind tower fabrication

        - Pressure vessels

        - Pipe assembly


    Configuration details
    FITZ Growing Line is complete with a group of 5 (five) rotators in two combinations:
    Fit-Up Bed & Growing Line

     

    Fit-up section for fit-up job consist of:

    Rotator A & B: Hydraulically adjusted idle rotator which fixed on ground and has two hydraulic cylinders to adjust center distance of rollers separately. 

    Rotator C: supporting roll which has two “v” shaped idle rollers to allow shells to be transported longitudinally when other rollers are retracted down and Rotator c support pipes.

    Fit-Up Bed & Growing Line

  • Growing section is for ‘growing job’ consist of two rotators.

  • Rotator D: Idler rotator- Rollers distance is adjustable by lead-screw positioning to handle different workpiece diameter and manual travel on rail.

    Rotator E: Power rotator - Rollers distance is adjusted by bolts positioning and motorized travel on rail.


    Scope of Delivery

    A.  1 Power section, 1 Idler roller bed

    B.   2 Fit up roller beds and hydrulic station

    C.  1 Hydraulic support v-roll

    D.  1 Electric control system

        1 Main control panel
