Trailer loads for the Strates Top Spin:
1. center (base, towers and arms)
2. auxillary (doghouse, feet, outriggers, platforms, 3 counterweights and water tanks)
3. tub load (trailer doubles as part of the loading platform)
4. scenery (28' van trailer)
5. Power plant (32' custom built)
6. computer container (10', rides on back of an extended semi tractor)
A special tractor is used for the center load since it is so heavy. That tractor carries three of the counterweights and the two round Top Spin signs.
I think the special tractor, power plant and a crane were purchased from Government surplus. I know before the crane was painted it had a plaque saying "Department of the Navy".
