System comprises first and second guide sections for guiding the conveyance along the shaft and a head section for receiving the conveyance. Second guide section is located along the shaft in series with the first guide section and is arranged to guide the movement of the conveyance along the shaft by interacting with the conveyance as the conveyance moves along the second guide section. Head section interacts with the first guide section, so that when the head section receives the conveyance, said head section allows the conveyance to move from the second guide section along the first guide section. Guide system comprises an intermediate guide section of constant length for guiding the conveyance along the shaft and an upper variable length guide section extending from the intermediate section to adapt to changes in the distance between the intermediate section and the upper region of the shaft.
