Abstract:
1. A lifting system for supporting a conveyor to a structure and moving the conveyor to vary the angular position of the conveyor and control the flow of product into a transportable container comprising: a conveyor having a receiving end and an exit end for transporting product between a feed conveyor and the transportable container; a lifting portion for securing said conveyor to the structure and engaging said conveyor at at least one lifting point for moving said conveyor vertically at said at least one lifting point while maintaining the horizontal position of said conveyor at said lifting point; a base support for further securing said conveyor to the structure; a hinging portion having at least one hinged arm pivotally engaging said conveyor at a conveyor pivot and extending from said conveyor pivot to pivotally engage said base support; wherein said hinging portion pivotally engages both said conveyor pivot and said base support for allowing movement of said conveyor along an arced path at said conveyor pivot to vary the angular position of said conveyor and maintain the position of said exit end of said conveyor over the transportable container to control the flow of product into the transportable container as said lifting portion moves said conveyor vertically at said lifting point; said lifting portion having at least one first support bar with at least one first sprocket disposed thereon, said at least one first support bar being rotatable for rotating said at least one first sprocket and including a first chain that engages both of said at least one first sprocket and said at least one lifting point for moving said conveyor vertically at said lifting point as said first sprocket rotates; and said lifting portion having at least one first arm having a fixed length and extending from said at least one first support bar to a second support bar said second support bar having at least one second sprocket disposed thereon and in communication with said at least one first sprocket and including at least one second arm having a fixed length and pivotally engaging said second support bar and extending from said second support bar to pivotally engage said at least one lifting point.
