Rescue lift
摘要:
A rescue lift is provided wherein a frame supporting a rescue net is pivotally attached to a work boat by means of a rotating drive shaft positioned on the boat. A float is provided on the end of the frame opposite the drive shaft to enable the bottom of the net to be submerged in the sea at all times. The frame is free to rotate about its pivotal attachment as the ship rolls and pitches, thereby providing a safe means to rescue an incapacitated person in rough sea conditions. The drive shaft rotates the rescue lift between a pick-up position in the sea and a discharge position extending upwardly above the work boat. The rescue lift can be positioned in a stowed position in order to fully utilize the deck space of the ship.
