Watch how the system works as part of the manufacturing process for wind tower monopiles.

The video demonstrates a 300 ton growing line with 40-60 ton fit up system.

  • Proven to optimise production by over 60%.
  • High quality and consistent welding results decreases rework projects.
  • Increases safety – the vessel/workpieces are in full control from start to finish of the fabrication process.

Innovative growing line systems and automated can joining systems.

Key Plant growing line and automated can joining systems enable individual motorised adjustment of each axis under load, the work piece sections can be manipulated left, right, up, down (X, Y, Z axis) to join the cans together.

We manufacture linear precision systems with ball screw operation for smooth precision control and hydraulic options for thin wall material.

Key Plant growing line and ACJS systems reduce time & cost, increase customer productivity and gives a consistence to the fitting up and joining of cans.

Wind tower manufacturers

Primarily used in wind tower production, Key Plant Fit Up and Growing Line Systems are an innovative, cost-effective solution for increasing your welding and fabrication throughput for large diameter, cylindrical vessels.

Their innovative linear precision function ensures smooth, accurate, fast-aligning, levelling, and fitting up of the cans. They adapt to accommodate varying sizes of the vessel, minimising handling and maximising operator safety.
