Growing Line - FITZ Series

Stable Speedy Shells Joining and Growing Process

FITZ series shell Growing Line is used for three or more pipes/ shells assembly and welding job. FITZ Growing Line is equipped with two fit-up roller beds, which have four independent hydraulic height adjustment rollers, to ensure the assembly and welding job speedy with a high performance.

Wind Tower Production LineFeatures

- Wind tower fabrication

- Pressure vessels

- Pipe assembly

Configuration detailsFITZ Growing Lineis complete with a group of 5 (five) rotators in two combinations:

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.

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.

Growing line working follow

lStep One:Lay dwon the two shells on Rotator A & Rotator B, Rotator D & Rotator E by crane.

lStep Two:

Join the two shells by moving Roator E on rails;

Fit-up and align seam by adjusting rollers center distance hydraulic, then spot welding;

Full circular welding

lStep Three:

Jack-up the front end of finished two shells by operating Rotator C (V-roller);

Move the finished two shells to backside by operating Rotator E;

lStep Four:

Lay down the third shell on Rotator A, B by crane;

Repeat the same work from Step one to Step three till all shells are finished.
