1. Craning the Detectors: Practical or Just Possible?

2. The Two Hole Scenario
We need a crane that can lift at least 150 tons of full detector up from the bottom of a 300 foot deep shaft
Deep South Crane and Rigging of Louisiana builds and rents such cranes

3. Recommended Crane:
The VersaCrane CC9600 is a 750-ton Crawler Crane with the footprint of a Manitowoc M2250 or 4600.  It has a variable tail swing and a load-moment of 75,600 kip-feet.

5. 750-ton capacity Crawler Crane with up to 400 feet of Main Boom
750-ton capacity Crawler Crane with up to 400 feet of Main Boom.  Configuration VI test lift of 750 tons at 35 foot radius

6. Why a 750 ton crane?
This may be the smallest capacity crane that can handle the ~5000 feet of cable necessary to do a 300 foot lift.
Their web site makes a telling comment (see next slide)

7. From website:
“Deep South Crane & Rigging began as a pure equipment rental company called Deep South Rentals. After renting mostly rough terrain cranes to the Petro-Chemical industry for about 10 years, we purchased our first 300-ton class conventional crane, Demag TC1200. Within a few years, we had built a fleet of rigging type cranes of which our largest was a 440-ton Demag TC2000. At the time, it seemed impossible to find a larger crane that would be able to meet our working needs. So we embarked on an endeavor to design and build our own larger crane. This endeavor gave birth to the Versa Crane line, which now has 3 models:  CC9600,  TC24000  and  TC36000.”

8. Other rental products:
“In addition to Deep South's Versa Crane line, we also have a highly mobile fleet of truck cranes and cherry pickers.  Our conventional cranes range from 140 to 2500 tons.  Our hydraulic cranes range from 6 to 500 tons.  We also have 70 lines of self-propelled hydraulic modular steering platforms.  View a selected few of our many choices below.”

I’m not sure about its lift height capacity)

11. Rough costs:
These numbers are based on a quick telephone call with Mitch Landry of Deep South
Crane Costs:
500K$/week to bring it, set it up and use it for a week
I don’t know what happens to the cost when crane is moved on-site from one shaft to the other.
Transporter Costs:
20K$ to bring it to site and take it away
$250/hr usage

12. Conclusion
Cranes and transporters do exist which can make the two-hole scenario possible
We have to do a detailed schedule of detector moves to come up with costs that we can compare side by side between the two-hole and tunnel scenarios
