At a naval station in Connecticut, Barnhart was hired to remove a 20,000-pound hyperbaric chamber, which would be refurbished and eventually replaced. The crew used toe jacks to raise the chamber, then slid skates underneath.
Using those skates and a steerable dolly, they moved the chamber to the door, which faced a narrow alleyway.
There was limited space in the alley, so the 150-ton hydraulic crane was carefully maneuvered into place. The chamber was successfully lifted using the crane.
The chamber was loaded onto an over-the-road trailer provided by the manufacturer for transport. The process will be repeated in reverse for the reinstallation of the chamber.
