Abstract : The patent relates to a helicopter cargo lifting system wherein a cable and ball are guided into a socket on the end of a boom in a lowered, rest position. The boom is adapted to be raised to a vertical, cargo carrying position. Upon landing of the cargo, a spring and air check mechanism, cause the boom to be lowered rapidly to an intermediate position and then slowly to the rest position. The socket is automatically positioned to facilitate cable and ball withdrawal during the slow lowering movement of the boom.
