Introduced and tested in 2019, Solo-Driver Plus was used on a construction project for the first time in its history. The patent-pending foundation installation method installed 80 caisson foundations to support new steel structures for transmission line rebuild project in Adams and Waushara counties.
Set up and driving takes minutes to accomplish with Solo-Driver Plus with very little ground disturbance, making it faster and more environmentally friendly than traditional installation methods.
After the launch of the initial Solo-Driver design in 2015, a team of engineers focused on evolution of the excavator installed caisson concept. Solo-Driver Plus’s “H” design provided ATC the opportunity to improve drivability and corrosion resistance as well as simplify fabrication, potentially reducing associated costs. A second variation was also developed and initially tested that has the potential to be used on more heavily loaded structures.
ATC submitted a patent application for Solo-Driver Plus in February 2023 and anticipates being awarded a final patent sometime in 2024 or 2025. Solo-Driver and Solo-Driver Plus continue to be great examples of ATC’s spirit of innovation.
