Definitions

  • the invention relates to a lifting and/or storage arrangement for boats according to the preamble of claim 1.
  • Boats require dry storage to avoid algae growth without the need for antifouling painting. Also in freezing waters boats need to be lifted up. Typically, the boats are lifted from water and placed on a land area at the marina for dry storage, maintenance and repair. When boat is left in water for longer periods build-up of algae and barnacles on the boat hull. Maintenance of the boat hull, e.g. antifouling painting and other surface treatments requires a lot of work and is costly. Antifouling paints may also contain chemicals that have serious toxic effects on marine life. Therefore, many boat owners keep their boats out of the water when not using them.
  • the object of the present invention is to provide an improved lifting and storage arrangement for boats.
  • the object of the invention can be achieved by a boat lifting and storage arrangement according to claim 1.
  • the boat lifting and storage arrangement comprises a frame, a floating cradle configured to receive the boat to be lifted.
  • the cradle is movable along the frame between a retracted position, in which the cradle is on the frame, and an extended position, in which the cradle is configured to float in water.
  • the arrangement further comprises a drive mechanism for moving the cradle between the retracted and extended positions.
  • the boat lifting arrangement according to the invention is easy and simple to use, and no assisting persons, trailer or crane is required to lift and lower the boat.
  • As the lifting arrangement according to the invention is also used as a dry storage, costly and time-consuming transportation of the boat to a separate dry storage location is not necessary.
  • the boat lifting arrangement may also have a relatively simple structure.
  • the cradle has a first end and an opposite second end, the first end being configured to float in the water and the second end being pivotally connected to the frame when the cradle is in the extended position.
  • floating depth of first end of the cradle is adjustable.
  • the second end of the cradle is pivotable around a transverse axis relative to frame in the extended position.
  • the transverse axis is perpendicular to the direction of movement of the cradle along the frame.
  • the cradle is pivotally connected to the drive mechanism to allow the cradle to pivot around the transverse axis relative to the frame when the cradle is in the extended position.
  • the frame comprises at least one rail along which the cradle is movable between the retracted and extended positions.

  • the rails comprise stoppers configured to stop travel of the front wheels along the rails when the cradle is in the extended position.
  • the transverse axis is the same as the axis of rotation of the connecting axle when the cradle is in the extended position.
  • an end part of said at least one rail at the first end of the frame is downwardly curved and/or inclined.
  • FIGS. 1 show a lifting and storage arrangement 1 for boats according to an embodiment of the invention.
  • the lifting and storage arrangement 1 can be floating.

  • the pier module may be part of a pier that comprises a plurality of pier modules connected together.
  • the lifting arrangement 1 may be installed in a boathouse into which boat 4 is driven for storage.
  • the lifting and storage arrangement 1 comprises a frame 2.
  • the frame 2 is typically floating, but alternatively the frame 2 can be non-floating or fixed.
  • the frame 2 has a first end 2.1, from which the boat 4 is lifted out of water and lowered into water, and an opposite second end 2.2.
  • the frame 2 may comprise least one float 3, such as a pontoon or ballast tank.
