Abstract

A hoisting apparatus mounted on the deck of a ship for picking floating objects from the sea having an articulated lifting arm which extends over the side of the ship and gripping device suspended from the end of the arm for grasping objects in the water. The arm is actuated by an hydraulic cylinder connected to a source of high pressure liquid which may be dumped into the cylinder instantaneously in response to the closing of the gripping device around the object. The liquid is pressurized by a compressed gas. The apparatus produces a high hoisting speed and lifts the object very quickly from the water.
