In an overhead hoist transfer having a moving carriage with a hand portion, which holds a load, elevatably suspended therefrom; and a means for teaching an appointed stop position on a placement base, on which said load is placed, to said moving carriage, LEDs 7a and 7b are installed at the hand portion 6, and a position detecting portion 12 consisting of a lens 12a and PSD 12b is installed at the placement base 53 side, in order to automatically and accurately enable a teaching of position correcting data in a short time without use of any manpower. Further, a teaching portion is installed, which detects a deviation between the present stop position and the above appointed stop position on the basis of the relative position of the hand portion 6 with respect to the placement base, which is obtained by the position detecting portion 12, and carries out a teaching to the moving carriage by, for example, radio, whereby it is not necessary for an operator to carry out a teaching by actually moving the hand portion, wherein it is possible to accurately carry out a teaching of position correcting data in a short time.
