  • Patent number: 5507381
    Abstract: The invention provides a method for unloading a space filled with bulk material using at least one grab supported by a chassis, wherein the chassis is displaced in lengthwise direction of the space and wherein the grab is emptied above a cross conveyor, characterized in that the cross conveyor is moved reciprocally each time relative to the chassis between a receiving position situated beneath the grab and a retracted position, while in the retracted position of the cross conveyor the grab is lowered into the space and raised therefrom filled with material and opened above the cross conveyor in the receiving position of the cross conveyor. Long bites of material are thus systematically removed each time from a hold in transverse direction of the hold.
