ABSTRACT:
The lifting system includes a lifting portion and a hinging portion for lifting a conveyor The lifting portion is fixed to a structure and extends from the structure to mate with the conveyor at a lifting point. The lifting portion moves the conveyor vertically upward and downward at the lifting point with no horizontal movement at the lifting point. The hinging portion is pivotally connected to the conveyor at a conveyor pivot and extends from the conveyor to engage the structure. The hinging portion is further pivotally connected to the structure to allow for controlled movement in an arced path at the conveyor pivot of the conveyor. The controlled movement of the conveyor along the arced path at the conveyor pivot varies the angular position of the conveyor and maintains the position of the conveyor over the transportable container as the lifting portion moves the conveyor vertically at the lifting point.
