  • Patent number: 12151908
    Abstract: A storage and reclaim system for bulk material includes a bulk material holding space having a bottom portion provided with a discharge port. The bottom portion includes an inclined support plate for supporting the bulk material and for assisting gravity induced feeding of the bulk material towards the discharge port. The support plate is supported by a support structure in a free-floating manner. One or more vibrators are connected to the support plate and configured to transfer vibrational energy to the support plate to induce a vibrational movement of the support plate. The discharge port includes one or more inclined discharge port plates. One or more vibrators are connected to each discharge port plate.

  • Patent number: 10315732
    Abstract: The present invention relates to a vessel (200, 300, 400, 600) comprising: a cargo transloading system, comprising: a crane (210, 310, 410, 610) supporting a cargo handling device (318, 418), and a counterweight arrangement (450, 550). The cargo handling device (318, 418) being rotatable about a vertical axis of rotation arranged with a first fixed offset in a first side direction with regard to a first vertical plane coinciding with a longitudinal center axis (CA) of the vessel (200, 300, 400, 600). The counterweight arrangement (450, 550) comprising a weight (452, 552, 652) which is movable such that the mass center (554) of the weight (452, 552, 652) is laterally displaceable between a first end position (556, 656) in which the mass center (554) is arranged in the vicinity of the first vertical plane and a second end position (558, 658) in which the mass center (554) is arranged with a second offset in a second side direction opposite to the first side direction with regard to the first vertical plane.

  • Patent number: 6536363
    Abstract: Device for ships having at least one ship's ramp (2) which at an inner end (3) is pivotally connected with the ship and in a loading position at an outer end (5) is supported by an offboard surface (18) for cargo to be transported between a deck (7) of the ship and said offboard surface by means of the ship's ramp. The ship's ramp varies in angular relationship relative to the offboard surface due to movements in the water surface of the sea. The device (1) includes a platform (21), which is pivotally suspended in a base unit (27) by means of pivot means (28). The platform (21) has top support means (22) provided to receive and support the outer end (5) of the ship's ramp (2). The base unit (27) has bottom support means (43) provided to rest on said offboard surface (18).
