Title: Foldable boom assembly
Abstract:
A vehicle and foldable boom assembly includes an inner boom that extends outwardly from a side of the vehicle and an outer boom that extends outwardly from the inner boom to a working position. A hinge, having a pivot axis that is disposed generally vertically, interconnects the inner and outer booms and allows the outer boom to swing rearwardly to avoid structural damage upon impact with a foreign object; and the pivot axis is inclined in a direction that resiliently urges the outer boom forwardly to the working position so that the outer boom is automatically reset to the working position subsequent to impact with a foreign object.
