Abstract
A continuous-conveyance bulk-cargo ship unloader in which a boom is provided with an elephant trunk that can swing from one end of the boom. The trunk has a hollow cylindrical shaft which accommodates an upright conveyor. At the bottom of the elephant trunk, is a free-sweeping cargo-intake unit that is provided with a cargo pickup, a lower section of the conveyor, and a conveyor loader for transferring cargo from the pickup to the conveyor section. Squeeze rollers are mounted in horizontal frames and positioned at varied heights along the upright conveyor, and these frames have an uppermost frame attached to the shaft. The remaining ones of the frames are suspended from a frame above at three or more points. A lowermost frame is releasably fastened to the cargo-intake unit and pivots along with the cargo-intake unit about a vertical axis at the bottom of the shaft. The trunk is arranged inclined to swing in both directions.
