Definitions

  • the invention relates to a floating dock consisting of a lift platform with upright posts at the long sides of the platform, wherein the dock's float bodies are supported on pivotable brace members and disposed externally of the dock and the dock's platform can be raised and lowered in relation to the float bodies.
  • US Patent 3,415,212 describes an assembly with separately adjustable float bodies, but this is a rather large construction in which cylinders force the float bodies to pivot while in the water. This assembly is complicated and not suitable for use as a small, simple drydock.
  • the object of the invention is to obtain a floating dock which is as simple and robust as possible, while at the same time it can be controlled, i.e., raised and lowered, by simple mechanisms and is also as stable as possible in the lateral direction.
  • Figure 1 shows a floating dock in accordance with the invention, seen from one end, and Figure 2 shows the floating dock of the invention as seen from above.
  • the lifting pontoons 1 for the floating dock of the invention are made as tubular, elongated bodies and are disposed along the two long, sides of the floating dock.
  • the work deck of the floating dock is designated by numeral 3.
  • upright columns or posts 2 are provided, preferably two on each side.
  • the lifting pontoons or float bodies 1 are connected to the floating dock by a swivel link which preferably is attached to the upright posts. Between the swivel link and a point higher up on the post, hydraulic cylinders are attached, which are intended to guide the float bodies between the two positions indicated in Figure 1 with solid and broken lines.
  • the hydraulic drive means can be arranged within the post itself, which preferably is formed as a hollow cylinder, or on a raised work platform arranged between two posts. The person using the floating dock can stand on the raised work platform and control the movements of the floating dock, raising or lowering the dock in the water.
  • Stabilizer tanks 4 are provided underneath the work platform, extending transversely of the work deck and giving the work platform or floating dock a buoyancy that approximately equalizes the platform's weight. This permits the float bodies to support the weight of the boat that is placed on the platform.
  • a floating dock of this type can be used in connection with docking of ships and smaller vessels, or for raising and lowering other equipment in a maritime environment.
  • the assembly of the invention has the following advantages:
  • the platform can be raised and lowered rapidly at the desired rate of speed, for example, as quickly as 20 seconds.
  • No interior maintenance is required, since all pipes and pontoons are hermetically welded and sealed and may optionally be filled with polyurethane foam or the like. in that case, buoyancy will not be lost if the pipes or pontoons become punctured owing to a collision or corrosion damage.
  • the pontoons are positioned externally of the platform, unusually good stability is obtained, especially during raising and lowering of the platform, d)
  • the dock does not require a piping system for filling/ emptying the tanks during operation. e) The dock can raise itself, thus permitting exterior cleaning and maintenance to be performed easily.
  • the platform can be moved into shallow water, where it can then be raised up above the ground and "stand" on the float bodies, thereby providing access to the underside of the platform for maintenance.
  • the movement of the float bodies can be undertaken independently on the two sides of the platform, permitting one to compensate for imbalance caused by the object placed on the platform. Independent adjustment of the float bodies also allows one to counteract heavy seas running against one side of the platform.
  • the platform is especially intended for use in connection with pleasure craft and smaller fishing boats.
  • a small floating dock is provided which can be operated rapidly, which is highly stable and which may easily be transported to the desired site for use.
  • the platform can also be used for transporting objects over shorter distances at sea.

Abstract

Un dock flottant comporte une plate-forme d'élévation (3) avec des montants verticaux (2) sur les grands côtés de la plate-forme (3), ainsi qu'une série de flotteurs (1). Les flotteurs (1) sont soutenus par des éléments de support pivotants à l'extérieur du dock. La plate-forme (3) du dock peut être élevée et abaissée par rapport aux flotteurs (1) par l'actionnement de cylindres hydrauliques (5) ou éléments similaires, qui sont situés entre les montants verticaux (2) de la plate-forme (3) et les éléments de support des flotteurs (1) des deux côtés de la plate-forme (3).
