<p>A carrier for a hauling system of the kind comprising a reciprocating pulling rope (25) which runs along the transport line, and a plurality of carriers (10) adapted to be removably attached to the rope at any desired position and to be released from the rope at a predetermined point in order to relieve the load. The carrier comprises a housing (11, 12, 13, 14) which houses a lock which is adapted to be wedged against the rope and to bring along the load with the rope as this moves in one direction and to slip on the rope without moving the load as the rope moves in the opposite direction. The lock comprises a wedge member (20) which is wedge shaped in itself and is restricted movable in the housing and which is adapted to rest against the rope under at least some friction also in rest position, during the return stroke of the rope. The wedge member (20) has a length of from at least two and up to preferably five or more times the diameter of the rope (25). The wedge member (20) may comprise two mutually spaced wedge elements (18, 19) which are joined to each other by means of an intervening web (26) and between which there is formed a sidewardly open channel (23) for the pulling rope (25).</p> |
