摘要： A method and apparatus for removing bottom material from beneath the surface of a body of water includes a floatable base upon which a tower is mounted for extending vertically upwardly therefrom. A rigid, elongate member having a bucket is connected to the tower and shiftable relative thereto by means of a power-driven motor mounted adjacent the tower. The motor is operable for selectively shifting the elongate member in a substantially vertical direction to effect raising and lowering of the bucket. A carriage is connected by cables to the motor and is operable for substantially vertical shifting along guides provided on the tower. The elongate member is connected to the carriage and suspended therefrom and is also pivotally connected to the carriage to permit pivotal movement of the elongate member about a horizontal axis extending generally perpendicularly to the longitudinal axis of the elongate member. A second carriage is provided on an opposite side of the tower and is operable for substantially vertical shifting along second guides provided on the other side. A counterweight is connected to the second carriage and suspended therefrom to aid in the raising of a bucket load of bottom material.
