Abstract: A transfer apparatus includes a guide rails extending parallel with each other, a vehicle configured to be movable along the guide rails, and a contactless driving module mounted to the vehicle. The contactless driving module includes a pair of running rails extending parallel with the guide rails and comprising a plurality of first permanent magnets and a plurality of second permanent magnets arranged in a extending direction, respectively, a driving wheel disposed between the running rails to be spaced apart from the running rails and comprising a plurality of third permanent magnets arranged in a circumferential direction, and a driving unit for rotating the driving wheel. Particularly, at least one of the third permanent magnets is disposed between the first permanent magnets and the second permanent magnets.

Abstract: Proposed are an OHT vehicle and a method of controlling the operation of the same. More particularly, proposed is a technology in which when a hand unit of an OHT vehicle loads a transfer container and unloads the same to a destination load port, an error between a recess of the transfer container and a positioning pin of the load port caused by the tilt of the transfer container is resolved through position correction of the hand unit, thereby enabling the transfer container to be accurately placed on the load port.
