A conveyor with a frame (8) supports a carrier device (32, 34) for load, the conveyor being supported by motor-driven wheels to effect a travelling movement along a predetermined track (14, 16) and/or the carrier device being movably supported in relation to the frame of the conveyor. Sensors are arranged to contactlessly detect the position of the conveyor on the track of travel (14, 16) in relation to a predetermined reference position and/or the position of the carrier device (32, 34) in relation to a reference position on the conveyor frame (8) and to deliver a corresponding train of pulses, each pulse corresponding to a certain distance of movement, for determining the position of the conveyor and/or carrier device by counting pulses.
