An apparatus for transporting cargo includes a rotatable support arm and at least one bracing arm that extending in a substantially perpendicular direction from the longitudinal arm. No more than one of the bracing arms contacts and supports a corner of the cargo. At least one of the bracing arms preferably includes an extendable assembly for providing at least partial support of the cargo. The extendable assembly may include, for example, a sleeve and a movable structure located within the sleeve, wherein the movable structure may be extended from the sleeve to contact the cargo.
