Squirters® have now been installed in over 100 Wind Turbine Generators in Central and North America. Owners, operators and erectors have discovered that Squirters® are an inexpensive quality assurance system to guarantee bolt tension.
One notable project will be visible to the world during the 2010 Winter Olympics. Grouse Mountain is a beautiful ski resort in North Vancouver, British Columbia. Last summer they installed a Leitwind LTW77 1.5 MW wind turbine on top of the mountain. This unique turbine, which will generate up to 25% of the resort’s electricity needs, has a view pod under the nacelle providing visitors a front row seat to see the turbine in operation.

The LT-77 tower is 65 meters tall, comprised of three sections. Engineers, concerned about using torque-based installation methods, specified Squirter® DTIs in the tower flange bolts to guarantee that the assembly crew hit the minimum pretensions without exceeding proof load. During assembly, the M36 bolts were “snugged”, bringing the flange surfaces into firm contact. The Squirters® then guaranteed that the target pre-tension was achieved +/-10% as certified by Germanischer Lloyd.
