FITA Growing Line

The FITA Series Shell Growing Line is used for three or more pipes/ shells assembly and welding jobs. The Growing Line facilitates the efficient production of large diameter tubular workpieces, typically used in wind tower fabrication. These expandable mounting rollers can be grown to fit the size of the workpiece and aid in precise alignment.

    Growing Line - FITA Series - Supply to Europe, USA and other countries

    OLIVTE specializes in the production of an innovative growth line system for the rapid alignment, leveling, assembly and indexing of large pipes, tanks and vessels. Weights up to 100 tons. The Growline reduces assembly time by 65%, minimizes crane operations, and maximizes operator safety compared to conventional methods.

    Stable Speedy Shells Joining and Growing Process

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