Hoisting device for transferring containerized cargo

摘要

A hoisting device (201) for transferring containerized cargo (203) is particularly suitable for transferring cargo (203) from and to ships at sea. The hoisting device (201) includes a base frame (205), a mast stabilized by rigging wires, a boom (215), a turntable, and at least one winch (275). The turntable supports at least the boom (215) for rotation with respect to the base frame in a substantially horizontal plane. The base frame (205) of the hoisting device (201) is adapted to he supported from and secured to at least three top corner fittings of a portion of the containerized cargo (203) to be transferred. The hoisting device (201) is preferably constructed such that all parts can he dismantled and transported by helicopters to a casualty or shipwreck. It can thereafter he rigged on board of the stranded ship to effect the unloading of a containerized cargo (203).
