ABSTRACT:
The present invention relates to a process for the removal of ore from the hold of a bulk carrier vessel. The prior art employes a boom mounted vacuum probe which is lowered into the ore material to effect unloading. This invention adds material handling hoses between the boom mounted vacuum probe and wheeled vehicles with attached aspirated suction nozzles. Further, the wheeled vehicles are powered from a stationary hydraulic pumping unit connected to the existing electric power of the boom mounted vacuum probe. Ore unloading efficiency is improved when the ore level in the hold reaches a depth of approximately two feet or less by providing wheeled vehicles carrying aspirated suction nozzles over the decking of the hold.
