ABSTRACT:
A lift line tension limiter is provided which includes a lift line and a tainer which is adapted to contain the lift line. The container has a lift end and a payload end, the payload end having an aperture for the passage of the lift line therethrough. A device is spring mounted to the container for pinching the lift line at the container aperture, and after the container aperture the lift line is in frictional engagement with the pinching device so that a force on the lift line will decrease the pinching action on the lift line. With this arrangement a predetermined loading of the lift line will spring bias the pinching device to relieve the pinching force and allow a portion of the lift line to be payed out of the container until the loading has been lessened below the predetermined amount.
