  • Patent number: 4023775
    Abstract: A rope connected to a chain cable by a connector is recovered using a chain cable lifter wheel. The connector is shaped to pass over the wheel, which has a groove for the rope. The wheel has pockets which can receive the connector and also receive chain cable links. Protuberances on the connector and stops in the pockets ensure correct seating of the connector in a pocket so as to ensure correct subsequent engagement of chain links with the pockets of the wheel.
