As technicians moved to other wind energy companies, they began asking why their new companies weren’t using the StudPuller. Suddenly technicians knew pipe wrenches were no longer the tool of choice to remove studs. Siemens Gamesa began testing the tools and very quickly added the StudPuller to their repair manual as the specified way to remove studs. Now the StudPuller was the proven method for removing studs in wind applications. Other leaders in the industry like Vestas, Iberdrola, NextEra and Suzlon began making the StudPuller the official stud removal tool of the wind industry.

TRW didn’t stand still with the original design. As technicians began to provide feedback on how to improve the tools, we added a steel insert into the drive portion of the tool for durability. The steel anvil of the wrench now makes contact with a steel insert. GE reported removing 400 studs on one set of jaws.

Some wind companies began experimenting with reusing studs and with faster stud installation. TRW went old school and redesigned a collet tool that threads onto the studs so no damage is done to the threads. It’s the TRW Threaded StudPuller and it comes in every possible size. We also designed a stud installer that uses “secret sauce” so that the stud never sticks in the tool. Torque the stud down with confidence that the stud will stay torqued and the tool can be removed with no issues.
