Hinged carriage deck for vertical reciprocating conveyor
A vertical reciprocating conveyor that can be transported in a storage condition and assembled at a work facility in an operating condition. The vertical reciprocating conveyor includes a carriage assembly that is movable along a pair of spaced vertical rails of a support frame. The carriage assembly includes a pair of spaced uprights and a carriage deck designed to support material moved along the pair of spaced vertical rails of the support frame. The carriage deck is movable between an operating condition and a storage condition, where the carriage deck is perpendicular to the pair of spaced uprights in the operating condition and parallel to the pair of spaced uprights in the storage condition. The movement of the carriage deck allows the overall size of the vertical reciprocating conveyor to be reduced for shipping.
1. A vertical reciprocating conveyor comprising:
a frame including a pair of spaced vertical rails;
a carriage assembly movable along the pair of spaced vertical rails; and
a drive mechanism operable to move the carriage along the pair of spaced vertical rails between a plurality of vertical positions,
wherein the carriage assembly comprises:
a pair of spaced uprights;
a pair of pivot brackets each mounted to a lower end of one of the pair of spaced uprights, each of the pivot brackets including a pair of spaced arms that extend perpendicular to the pair of spaced uprights; and
a carriage deck including a pair of spaced side beams and a platform mounted between the pair of side beams, wherein the pair of side beams define an entire width of the carriage deck and each extend between an outer end and an inner end, wherein of the side beams is pivotably mounted between the pair of spaced arms of one of the pair of pivot brackets at a mounting location spaced from the inner end of the side beam, wherein the side beams are pivotable between the pair of spaced arms of the pivot brackets and are movable between an operating condition and a storage condition, wherein the carriage deck is perpendicular to the pair of spaced uprights in the operating condition and parallel to the pair of spaced uprights in the storage condition.
2. The vertical reciprocating conveyor of claim 1 wherein each of the pivot brackets includes a pivot pin and a locking pin, wherein the pivot pin provides a pivoting connection between one of the side beams and the pivot bracket and the locking pin is positionable at a location between the pivot pin and the inner end of the side beam to secure the side beams to the pivot bracket when the carriage deck is in the operating condition.
3. A carriage assembly for use with a vertical reciprocating conveyor including a frame having a pair of space vertical rails and a drive mechanism operable to move the carriage assembly along the pair of vertical rails, comprising:
a pair of spaced uprights;
a pair of pivot brackets each mounted to a lower end of one of the pair of spaced uprights, each of the pivot brackets including a pair of spaced arms that extend perpendicular to the pair of spaced uprights; and
a carriage deck including a pair of spaced side beams and a platform mounted between the pair of side beams, wherein the pair of side beams define an entire width of the carriage deck and each extend between an outer end and an inner end, wherein of the side beams is pivotably mounted between the pair of spaced arms of one of the pair of pivot brackets at a mounting location spaced from the inner end of the side beam, wherein the side beams are pivotable between the pair of spaced arms of the pivot brackets and are movable between an operating condition and a storage condition, wherein the carriage deck is perpendicular to the pair of spaced uprights in the operating condition and parallel to the pair of spaced uprights in the storage condition.
4. The carriage assembly of claim 3 wherein each of the pivot brackets includes a pivot pin and a locking pin, wherein the pivot pin provides a pivoting connection between one of the side beams and the pivot bracket and the locking pin is positionable at a location between the pivot pin and the inner end of the side beam to secure the side beams to the pivot bracket when the carriage deck is in the operating condition.
5. The carriage assembly of claim 4 wherein the pivot pin extends through the one of the pair of pivot brackets and one of the pair of side beams at a location spaced from the inner end.
