A transport apparatus (2) for conveying a product is disclosed. The transport apparatus (2) comprises a movable conveying element (8) which is intended to convey the product and has a pattern (52) which extends over a predetermined pattern length (66) in the direction of movement (16) of the conveying element (8) and has a multiplicity of travel increments (56, 58); a stationary, peripherally arranged running rail (6) which defines a running path (14) for the conveying element (8) and has a multiplicity of position sensors (20) on the running path (14), the distances (18) between which are shorter than the pattern length (66); and a measuring device (12) which is designed to determine an instantaneous position of the conveying element (8) on the running path (14), wherein, when the pattern enters and/or exits the measuring region (48) of a position sensor (20), the measuring device (12) determines the instantaneous position with respect to a reference position of the conveying element (8) on the running path (14), said reference position being derived from the position of the corresponding position sensor (20), monitors at least one of the position sensors (20), in the measuring region (48) of which the conveying element (8) is located, and increments or decrements the instantaneous position if a travel increment (56, 58) passes a position sensor (20) being monitored.
