Barnhart was hired to remove a 50-year old transformer from a site in New Hampshire and replace it with an onsite spare transformer. The team first had to remove concrete ballistic walls and columns to gain access to the transformers. They used pull-up gantries to lift the mammoth transformer, which weighed approximately 850,000 lbs.
Once lifted, Barnhart used their 16' slide system to jack and slide the old transformer to a staging area for onsite demolition. Barnhart crews slid the 425-ton piece over 125' to its staging area.
The spare transformer, which weighed 560,000 lbs. was readied for transport using the 16" slide.
It was transported 200 yards from onsite staging to its final location. The job was completed safely and efficiently
