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

The design of the tools is aiming for simplicity to have reduced cost and intuitionality for the operator. There are for instance no additional engines used to operate the tools. Instead the use of a standard cordless screw-driver system is foreseen. This can be adopted using a universal fixation system matching with a large variety of tools. Visual signals show if the tensioner is handled within its limits (especially correct bolt protrusion and maximum piston stroke) to increase worker safety. Also the handwagon is not using any motors. For tangential movement on the flange handforce is sufficient. The integrated tool lifting mechanism supports the operator with a system of 2 or more gas-springs to reduce the required handforce for lifting during operation.

Areas of Application

SCHAAF FSTS is the optimal solution, where constant monitoring can prevent damages or injuries. Additional estimated bolt loads during design stage can be proved if correct. Especially for connections with permanent vibrations, weather related and temperature changes or load changes, for example wind turbines, bridge construction, cranes, electric generators and motors.

Qualität

Quality Assurance

All FSTS are checked for 100 % process security. During order handling, they are accompanied by ongoing quality assurance measures and supplied with extensive documentation.
