With traditional material handling methods, it takes days to move multi-ton containers and equipment in or out of the plant for maintenance or replacement. With air casters, staggeringly heavy loads can be moved by one person or a very small team. Net plant downtime is reduced to hours versus days when air casters are used, as more and more power plants are proving. A system engineer stated "Air casters are a safer way to move feedwater heaters. With rollers, the heater could fall off. One tank we moved at another plant weighed 200,000 pounds. I've used air casters three times and, in my experience, none has ever failed. There are hundreds of these feedwater heaters in other plants across our system and they're starting to pick up on this as well. It's been established as the best practice across our company."
"We used the AeroGo air casters to drift the vessel into the mezzanine floor. We had columns, other pieces of equipment and valves in the way. It's like threading through the eye of a needle. The new heat exchanger had to be set back in the exact place we pulled the other one out of. We had a 30-foot long vessel, six feet in diameter, and weighing 60,000 pounds. We needed to get it set within about a quarter inch of where the other one was set. Once we got it in there, the air casters made it easy to move the vessel around—you could bump it just a little bit."
AeroGo air casters ease floor loading issues and precisely position the heaviest loads. "The load is spread out over a huge area— it's virtually the same load as you'd put on the floor by walking across it." Air casters are omni-directional and can easily traverse corners and make u-turns or spin a load around and back it out or in. It is air caster maneuverability that makes placement "accurate to a quarter of an inch" possible.
The air caster methodology for moving casks and containers in nuclear power plants was heralded at the International Conference on Nuclear Engineering in 2004.
