International Classification:

B60P 1/04

US Classification:

410 77

Abstract:

A support structure for supporting and tilting an oversized cargo to reduce the effective width of the cargo. The structure comprises a frame having a base and a stanchion connected to the base. A rocker arm is pivotally coupled to the stanchion to pivot about a pivot axis. The arm includes a first and second end disposed opposite one another. The arm has a center of gravity disposed between the first end and the pivot axis and that biases the arm to pivot in a first pivotal direction. First and second brackets are positioned near the first and second ends of the arm for receiving the cargo. The cargo has a center of gravity disposed between the pivot axis and the second end that causes the arm to pivot in a second pivotal direction opposite the first pivotal direction.

International Classification:

B61D 45/00

US Classification:

410101

Abstract:

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.
