FSTS

SCHAAF solution for a Tower Flange Stud Tensioning System Documentation – Efficiency – Quality

The design of the tools is focused on simplicity in order to reduce costs and enable more intuitive operation. For example, no additional motor is used to operate the tools. Instead, a standard cordless screwdriver system is used with a universal fastening system that fits a wide range of tools. Visual signals indicate whether the tensioner is being operated within its limits (in particular correct bolt protrusion and maximum piston stroke) to increase work safety. The handwagon also works without motors. Manual force is sufficient for the tangential movement on the flange. The integrated tool lifting mechanism supports the operator with a system of two or more gas springs to reduce the manual force required for lifting during operation.

ADVANTAGES

  • Optimized Tool design: All parts are designed for min. 100.000 LC. Service interval is 10.000 LC/12 months and preventing collision with obstacles (tower wall, cable tray, ladder, weld seams) for a long life-time and simple handling for the operator
  • Suitable for marine and offshore environment: robust against outer influences up to Ip67
  • Increased lifetime of the bolt connection: TTG increases the possible residual force of a bolt connection and OBLM is used for real time load monitoring
  • Full documentation including bolt elongation, residual force and flange gap evaluation for every bolt connection to achieve maximum security
