WTF Series – the Wind Turbine Foundation Series

The Tentec Aero WTF series is designed for foundation bolts of wind turbines both metric and imperial up to 75,000 PSI and 150,000 PSI class.

  • One Pull Stretch: 25 mm (1") stroke length. The piston returns on spring force.
  • Larger penetration through nut: because the concrete height varies a bit more, the construction is that additional penetration is possible. Minimum remains 1 x diameter
  • Pierce too short: if the long stroke is precisely a disadvantage, a standard stroke can also be supplied and stretched in 2 or more steps.
  • Rotatable hose connection: The WTB series is equipped as standard with a rotatable hose connection so that the hose always drains optimally. This is very safe when working at 1,350 bar.
  • Nut run-down mechanism: a simple gear system allows the nut to be easily run down after preloading using a gearbox + hand wrench on the outside of the tensioner. This ensures consistency of the result in residual bolt load, i.e. after the oil pressure returns to zero.
  • Safety and reliability: The series has existed for more than 15 years and has been extensively tested in practice. All parts have a (safety) function.
