  • Patent number: 4059846
    Abstract: A device for suspending a raft from a transport such as a helicopter so that the raft can be lowered and raised into and out of the water without subjecting persons attending or occupying the raft to an electric shock from a static charge that may be carried by the transport. The device comprises a metal plate attachable to the transport having straps provided with snap fasteners releasably attachable to the raft. A ground wire connected to the plate is sufficiently longer than the straps so as to contact the water and ground the transport before the straps contact the raft.
