Apparatuses, systems and methods include support brace(s), one or more of which are configured to support a receiver apparatus relative to a frame and define an opening that is configured to receive and orient a post along a vertical axis. A stator element coupled to one or more of the support brace(s) is rotationally fixed relative to the one or more support brace(s) about the vertical axis. A rotor element is configured to pivot about the vertical axis and includes a base and a package holder. The package holder includes a proximal end, a distal end, and an elongated body therebetween. The proximal end is coupled to base such that the elongated body extends at least partially in a radial direction relative to the vertical axis. The actuator is configured to receive an activation signal and pivot the rotor element relative to the stator element about the vertical axis.
