1. A material handling system for delivering a plurality of items to or from a plurality of destination areas, wherein the system comprises:
- a plurality of delivery vehicles for delivering the items to the destination areas;
track for guiding the delivery vehicles, wherein the track comprises a substantially vertical portion and a substantially horizontal portion and a gate providing a continuous path from a horizontal to a vertical direction;
where each of the vehicles comprise;
a transfer mechanism operable to transfer an item between the vehicle and one of the destination areas;
a drive element operable to drive the transfer mechanism; and
a gate actuator operable between a first position in which the actuator does not actuate the gate and a second position in which the actuator is operable to actuate the gate, wherein actuating the drive element of the transfer mechanism actuates the gate actuator from the first position to the second position.
