Pulled into an I-90 rest stop west of Albany NY and saw what appeared to be a large water tank on a flatbed, parked next to … an airplane wing?
Nah, this can’t be.
Turns out that the “tank” (in the distance of the picture) was part of the mast for a wind turbine, with three airfoil blades on separate trailers scattered around the edges of the truck parking area.
This being a Marching Band trip (returning from the NYSFBC Dome contest in Syracuse: 4th place), I deployed two bandies as measuring instruments. They put on their drill face, stepped 8-to-5 along the blade, and reported it as 120 feet, which agreed well with my uncalibrated 125-foot pace.
Seen end-on, a blade doesn’t present much to see. The plastic-foam endcap is a nice touch, though.
The hub and generator nacelle (and, most likely, many more tower sections) were missing from the collection, which leads me to think they’re marshalling all the pieces before delivery to a wind farm site. It’s also possible these came from a decommissioned installation, as they seemed somewhat weathered.
A semitruck driver said they’d been parked in the lot since late last week.
The placard on the back of the trailer reads, in both English and French (due to a Quebec license plate):
CAUTION THIS TRAILER OFFSETS
A bit of Google-fu (try searching for offsetting steering semitrailer -carbon) indicates that the trailer has self-steering wheels, which makes sense given that it’s a single unit rather than a double-bottom semitrailer rig.
The tower section had a bogie wheel assembly strapped to one end (labeled “TOP” on the canvas cover) and a semitrailer tongue strapped to the other: no need for a trailer between the two, as a cylindrical turbine tower is certainly stronger than anything you’d find on the road.
