A method of reducing the effective width of cargo, such as a concrete double-tee. The method comprises positioning the arm in a first position in which the arm is substantially horizontal, the arm being pivotally biased toward the first position, lowering the double-tee onto the arm such that the first leg of the double-tee is received by the first bracket and the second leg of the double-tee is received by the second bracket, and pivoting the arm and double-tee to a second position in which the second end of the arm contacts the base to support the arm, the arm being biased toward the second position when the arm supports the double-tee. The concrete double-tee includes a deck, a first leg and a second leg. The support structure includes a base, a stanchion extending upwardly from the base, an arm pivotally connected to the stanchion and extending between a first and second end. The arm includes a first bracket disposed near the first end and a second bracket disposed near the second end.
