  • Patent number: 10822213
    Abstract: A spooling device for facilitating spooling of a wire on a drum winch from a feeding point includes a suspension cradle mounted to the mechanical frame. The suspension cradle supports a rotatable wire sheave or receiving the wire extending form the feeding point and for guiding the wire to a specific location on the drum winch. The suspension cradle having the wire sheave is slideably mounted to the frame in accordance with a curved path. The curved path is configured such that the fleet angle of the wire extending from the feed point is at least partially compensated in order to reduce fringing effects of the wire on the wire sheave during sliding movement of the wire sheave along its curved path.
