Transformer Replacement at a GM Assembly Plant

Siller Helicopters, Inc. > Siller In Action > Transformer Replacement at a GM Assembly Plant

Project date: December 20, 2022

Prior to the Christmas holiday ’22, Siller was called upon by Nooter St. Louis – a national, multi-craft commercial contractor, to help replace five, 8-ton transformers at the General Motors assembly plant in Wentzville, MO, along one its truck assembly lines. The Skycrane S-64E was used due to its capabilities to support the weight of the transformers, but also for its anti-rotation apparatus, to help control the positioning of the units in and out of a small opening atop one of the plant buildings.

According to Jon Byrd, the lead electrician on the project, Siller was used because of the tight timeframe involved, in order to retrieve and place five units before impending weather hit the region. Siller had conducted the required transformer swap out in just two of the scheduled four days for the project. Siller was also used due to the threading-the-needle aspect of the roof, to get the transformers in / out of the assembly line, through a ultra-tight opening. The Siller safety record / processes also aligned to the requirements by both Nooter and GM.

“I have been in the construction industry for over 28 years. In that time I have done several critical picks – helicopter and crane picks, complicated jobs with tight timeframes and schedules. Siller’s project execution is near the top of that list, and Siller’s safety protocol aligns well with Nooter’s culture. As far as helicopter pilots, the best I’ve ever worked with. We will definitely be contracting with Siller again.”
