Dynamic processing of objects provided in elevated vehicles with evacuation systems and methods for receiving objects

A method of evacuating a trailer of a tractor trailer, said method comprising:

• coupling a coupled end of a collection conveyor to an evacuation conveyor, the evacuation conveyor configured and operable to change elevation in a substantially horizontal orientation;
• rotating a base end of the collection conveyor in a first rotational direction with respect to the coupled end of the collection conveyor such that first surface of the collection conveyor faces a plurality of objects to be removed from the trailer of the tractor trailer;
• contacting the plurality of objects with the first surface of the collection conveyor;
• activating the first surface of the collection conveyor to move the plurality of objects along the collection conveyor toward the evacuation conveyor;
• and
• rotating the base end of the collection conveyor in a second rotational direction with respect to the coupled end of the collection conveyor while the plurality of objects is being received by the collection conveyor, the second rotational direction being opposite the first rotational direction.

A trailer unloading system for unloading a plurality of objects from a trailer of a tractor trailer, said trailer unloading system comprising:

• a collection conveyor including a base end and an opposite coupling end, the coupling end for pivotally coupling to an evacuation conveyor, the collection conveyor including a first surface on which objects are to be transported to the evacuation conveyor;
• an elevation system that permits both the evacuation conveyor to elevate in a substantially horizontal orientation and the coupling end of the collection conveyor to be elevated relative the base end of the collection conveyor such that the first surface of the collection conveyor faces the plurality of objects in the trailer of the tractor trailer;
• and
• an activation system for activating the collection conveyor to move the plurality of objects along the first surface of the collection conveyor toward the evacuation conveyor.
