Abstract
A material handling system for continuous reclaiming or unloading of bulk cargo from the 'dead flow' regions of a ship hold. An unloading conveyor is positioned in underlying relation to the hold substantially centrally of the transverse dimension of the hold and moves lengthwise of the hold. The bottom of the hold is provided with gated discharge hoppers in overlying and discharging relation to the unloading conveyor. A suspended reclaim scraper is provided on each of the opposite lateral sides of the longitudinal axis of the ship hold to transfer bulk material laterally from the respective 'dead flow' regions to the centrally located discharge hoppers and thus to the underlying unloading conveyor. Each reclaim scraper is suspended by a cable hoist system from a suspension head carried by a trolley which is traversible lengthwise of the hold along a track positioned in the upper portion of the hold, whereby to traverse the reclaim scraper longitudinally of the hold. The track extends in overlying relation to a plurality of holds through an aperture or apertures extending through the bulkhead or bulkheads separating the plurality of holds. The cable hoist system provides the upward or downward movement of the reclaim scraper. Mechanism is also provided for 'slewing' the suspension head and the reclaim scraper supported thereby through an angle of 90.degree. in a horizontal plane to permit movement of the suspended reclaim scraper through the aperture in the upper portion of a bulkhead from one hold to an adjacent hold.
