  • Apparatus and method for replacing cable or wire in a hoisting system
    Patent number: 10351396
    Abstract: A method for replacing a length of a wire/cable in a hoisting system. The wire/cable extends from a storage drum to a winch. The method includes removing at least one lock which prevents a deadline anchor arranged between the storage drum and the winch from rotating, reeling onto the storage drum a first length of the wire/cable with a simultaneous coordinated operation of the deadline anchor and the storage drum, the simultaneous coordinated operation being controlled so that the wire/cable is in a continuous tension between the deadline anchor and the storage drum, securing the wire/cable to an attachment point, cutting a section of the wire/cable between the attachment point and the winch and removing the cut section of the wire/cable, reattaching the wire/cable remaining to the winch, reeling out a second length of the wire/cable from the storage drum, and securing the wire/cable to the deadline anchor.
