| 摘要 |
A method of loading and unloading a vessel with heavy objects whereby an object is vertically lifted, for instance from a vehicle drivable on a quay, by means of a crab, gantry or the like which together with said object is moved horizontally along girders from the lifting position to a position above the hold of the vessel. Said girders are arranged on the quay, extending in a cantilever manner out beyond the edge of the quay substantially up to the adjacent edge of the hold. From said cantilever girders the crab together with the object is moved over to and along horizontal extensions of said girders. These extensions, which are entirely supported by the vessel, bridge the hold. When the crab with the object has reached a suitable position on said extension and above the hold, the object is lowered into the hold. Also described is an equipment intended for carrying out said method into effect. |
