The Port of Brisbane, Australia is home to approximately thirty Super B Double combinations operating around the clock with two shifts most of the year. Permits obtained from the Queensland Department of Transport allow these trucks a maximum gross weight of two hundred and forty thousand, three hundred pounds. When loaded all axle weights are recorded using onboard scales. At ninety eight feet in length and moving two forty foot or four twenty foot cargo containers at once, they are restricted to just six roads within a one mile radius of the wharf area, servicing a dozen container facilities.

Both trailers feature a self steering mechanism on the rear axle that turns a few degrees when cornering. During reversing an air operated pin locks off the steering rear axle automatically on both trailers. One wharf requires these vehicles to be reversed over one hundred and fifty feet into a loading grid with a tolerance of just six inches each side. Some experienced drivers achieve this in one movement, perfect to less than one inch.
