  • Patent number: 10287746
    Abstract: A wide format dredge apparatus provides a floating vessel or hull with one or more anchor lines, anchors or spuds that enable an operator to hold the hull in a selected locale. Port and starboard booms extend in generally opposite directions from the hull. An elongated ladder is pivotally attached to the hull. The ladder is configured to swing between port and starboard positions. Port and starboard swing devices are rigged to the booms. When the ladder swings to the port position, the starboard swing device is lengthened and the port swing device is shortened. When the ladder swings to the starboard position, the port swing device is lengthened and the starboard swing device is shortened. Each swing cable spans from a boom at a position spaced away from the hull to the outer end portion of the ladder. A lifting device is provided for raising and lowering the ladder. A float or tank travels along the ladder. The float or tank at least partially supports the ladder.

  • Patent number: 10287748
    Abstract: A dredge and spud apparatus provides a dredge or hull or floating tank. The hull supports one or more spuds. An interface mounts each spud to the hull. The interface includes a frame attached to the hull and a carriage supported by the frame for movement between a forward position and a rear position. The hull can support one or more dredge components. The hull can be a barge. The carriage can be moved from the forward position to the rear position (or from the rear position to the forward position) in order to change position of the hull or floating tank relative to the spuds when the spuds are anchored to the water bed, sea bed, lake bed, river bed, etc. The interface includes inner and outer links, at least one link being powered to move between forward and rear positions.
