MATERIAL HANDLING EQUIPMENTCan be used for both bulk <strong>and</strong> unit movement of materialsAir pressure is used to convey materials through a system of vertical <strong>and</strong> horizontal tubes<strong>Material</strong> is completely enclosed <strong>and</strong> it is easy to implement turns <strong>and</strong> vertical moves12(a) Dilute-phase pneumatic conveyorMoves a mixture of air <strong>and</strong> solidPush (positive pressure) systems push material from one entry pointto several discharge pointsPull (negative pressure or vacuum) systems move material fromseveral entry points to one discharge pointPush-pull systems are combinations with multiple entry <strong>and</strong>discharge points12(b) Carrier-system pneumatic conveyorCarriers are used to transport items or paperworkExamples: transporting money to/from drive-in stalls at banks <strong>and</strong>documents between floors of a skyscraper13. Vertical conveyorUnit + On-Floor + No AccumulationUsed for low-frequency intermittent vertical transfers a loadto different floors <strong>and</strong>/or mezzanines (cf. vertical chainconveyor can be used for continuous high-frequencyvertical transfers)Differs from a freight elevator in that it is not designed orcertified to carry peopleCan be manually or automatically loaded <strong>and</strong>/or controlled<strong>and</strong> can interface with horizontal conveyorsAlternative to a chute conveyor for vertical “drops” whenload is fragile <strong>and</strong>/or space is limited13(a) Vertical lift conveyor30
