We are spending the night at the Florida Department of Transportation weigh station located at mile marker 13, west bound Interstate 4, in Seffner, Florida.
This is one of Florida’s newly renovated stations, with state of the art scales and utilizes laser technology. When a truck pulls in, it is scanned by 9 laser cameras that presents a 3 dimensional image on the controller’s computer screen.
It gives the operator the height, width, length of the tractor and the trailer, as well as distance between axles. Along with the scale, that measures weight of the cab and separate weight of the trailer, it is like a cat scan of the truck.
In talking with the station master, we learned quite a bit about truck weight and violations. For example, some trucks will be randomly selected to be fully inspected, including undercarriage.
As the truck pulls onto the scale, it’s weight is compared to it’s dimensions and axles,
which determines if the truck is in compliance with the law.
This truck is overweight on one axle. However, the driver can move that axle to distribute the weight more evenly, and therefore come into compliance.
This truck has a length violation. To correct that, the driver can move the king-pin to make the length shorter.
Tidbit of Information: Maximum truck length is 51 feet measured from the front of the cab to the center of the rear axle. By moving the kingpin forward, that moves the trailer closer to the cab, and therefore shortens that distance. Maximum height of tractor trailer is 13 feet 6 inches. The Sphinx is 13 feet 5 inches.
We met 2 other rigs from our Alaska trip here, and will all be going together tomorrow to the Tampa RV Show.
