Truck mounted extensible conveyor system
First Claim
1. A mobile power driven conveyor for moving packages or other objects to and from various elevated locations, comprising:
- a base element secured to a frame of a vehicle;
an inner boom structure rotatably secured to the base element;
an outer boom structure pivotally secured to the inner boom;
a conveyor belt extending along the inner and outer boom and over a plurality of support members to form an upper conveying flight along top portions of the inner and outer booms and a return flight along lower portions of the inner and outer booms; and
a conveyor belt tensioning mechanism disposed within the inner boom structure wherein when in a conveying mode the inner and outer booms are capable of being aligned with one another to increase the overall length of the conveyor and when in a highway mode are configurable at roughly a 90 degree angle to one another.

Abstract
A truck mounted conveyor system for transporting building materials to a station remote from the truck. The truck with conveyor system comprises a base platform mounted to the truck frame and an inner boom pivotally mounted to the base platform and configured to extend outward of said bed platform over a range of elevations and azimuths. The outer boom pivotally secured to the inner boom with a continuous conveyor belt circumscribing the inner and outer booms. The inner boom including a tensioner mechanism for maintaining a predetermined tension in the conveyor belt wherein the combination of inner boom and outer boom can be configured to minimize the overall length of the conveyor system while in transit in order to comply with applicable state overall vehicle length regulations and also maximize conveyor system length during conveying operations.
