Rigging History We only began rigging after we Installed about a hundred shields. We watched many companies from coast to coast move MRI's In and out of our shields. We saw the best and we saw the worst and every one in between. We sat on our hands patiently and waited for them to finish so we could close up our shield test and go home. When on occasion they damaged the floor , then we had to fix it. When they were a no show or delayed or Incompetent then we waited longer. When my workers are not working it cost me money. Thats when I decided it was time to begin rigging the MRI's we were shielding. It wasn't a question of how as we had been shown a hundred times what does and what does not work. So we purchased Insurance and some rigging equipment and that was that. I believe we now rig three magnets for every shield we build. We are not a paper company that subcontracts out your MRI rig.
Standard rigging includes a side entry to a building ,is about 25 feet in length , has one turn, and takes an average of a half day or more.
Top drops with roof hatches are easy to set normally but the longer crane reach is a few dollars more. foul weather can be an issue.
Air skate rigging jobs are required on expensive fragile marble, tile, and quartz floors as point loading is minimal. Air skating is also preferred on long flat runs with multiple turns. To this day our record longest rig was a 600 foot long rig on air skates in a Cincinnati Hospital. Air skates can make loud noises (squeals), require perfectly level floors, a compressor rental and can kick up any dust you didn't know was there.
Polyurethane equipment rollers on lexan sheet is our standard on most every job. Slow and secure on inclines softer than steel or nylon. This is standard for floor protection and it works well on hard surfaces. Carpet is not warranted to not crush under the weight of the magnet gantry. Protecting carpet under two layers of 3/4 ply and steel sheet is extra.
Pits, trenches, basements and crawl spaces under the rig path. We are not responsible if rig path you have chosen does not support the weight of the equipment moving over it. Structural engineering and shoring must be provided before rigging over blind voids.
Impossible MRI Rigging? So you built your new hospital and blocked the only exit to your old MRI. Oh yes it happens more often than you think. It may not be as impossible as you think.
Tight spots. We have been in some very tight spots. Although we prefer to not rub both sides of the MRI going through openings and hallways.
Ramps into the air that hold 20 tons on grass ? Sometimes its the only way. We have built quite a few of them.
Lift up or set down a 60,000 pound MRI through a hole in the floor, inside a building, with out a crane ,safely! We can do that. Our gantry lift was designed to lift up to 80,000 and is short as 9 or high as 13 foot . It can be built or taken down in a day.
Multi story rigs in tall buildings. Maybe I'm a adrenaline junkie. I borrowed a crane held platform (cookie sheet ) on my first multi story rig. It was huge and weighed more than the MRI. The cost of rental was as much as the rig. Then I did a couple tall platforms. Cheaper than the cookie sheet but too much work to build. the shoring was an entire truck load. So I drew up a plan and my sons welded me a fine light weight cookie sheet. The first time I used it was on a 40,000 second story. It was perfect and very safe. The craziest Job I ever took no now else wanted . 150 Michigan ave Down town Chicago. The Cookie sheet worked perfectly as I was rigging out a 36,000 pounder of that 40 story building. How crazy a rig was it? The crane permit and Insurance alone was $100,000.00
