Definitions

  • the present invention relates to a device for lifting a load, such as an intermodal container.
  • the invention is especially directed to a device for lifting container loads and other bulky loads to and from a supply ship that transport goods between a port and an offshore drilling or production facility.
  • the invention is also suitable for lifting loads between boats or between a boat and a port facility. It is common to load the goods into intermodal containers (i.e. standard sized containers), hoist the containers with the use of a crane on board the ship, and secure the containers on the deck of the ship. When the ship reaches the offshore facility the containers are hoisted, again by using a crane, on board the offshore facility. Empty containers and containers carrying waste material are in turn hoisted on board the supply ship for transport to the shore.
  • intermodal containers i.e. standard sized containers
  • the lifting unit would be much too bulky for pre-installation on the container before the container is shipped.
  • WO 2006/078170 shows a coupling frame which is connected to the load by slings.
  • the coupling frame can connect automatically to hooking head attached to a crane wire.
  • the coupling frame can rest on top of the load when not used for lifting.
  • a major drawback of the device according to WO 2006/078170 is that the coupling frame is fixed to the load only by slack wires or chains. Consequently, it is possible for the coupling frame to shift its position and it may also fall off the load and end up hanging down the side of the load, which will most certainly occur frequently with the movement at sea. This makes it difficult for the crane operator to mate the hooking head with the coupling frame. If the coupling frame falls off the top of the load, a person will have to put it back, and thereby put him- or herself at personal risk.
  • the coupling frame is made an integral part of the load. This removes the above disadvantages, but will require a very durable connection to the load.
  • GB 2408251 describes a device, which in some embodiments are similar to the device of WO 2006/078170.
  • the coupling frame is placed on top of the load but has parts that extend over the side edges of the load. This makes the frame very bulky and heavy. Despite this attempt to secure the frame on top of the load, it may shift at rough sea and due to being fairly large and heavy, it may also damage other containers on the ship.
  • the coupling frame is attached to the load through a telescopic guide tube.
  • a telescopic guide tube is highly susceptible to damage if the load should swing to a great extent during the lifting. This type of movement of the load will occur frequently when lifting is performed at sea.
  • the lower telescopic part of the guide tube will have to be fixed fairly well to the load, which means that it will take a considerable time to retrofit existing containers with this device.
  • a specific challenge of automatic lifting systems is that the lifting unit often must be oriented in a specific orientation to be able to mate with the
  • the present invention has as its primary objective to provide a device for load lifting, which is safe to use, removes the necessity for persons to be present on deck for connecting and disconnecting the load and the crane wire, and which can be easily retrofitted on existing containers.
  • the invention provides a convenient means for connecting a lifting unit to a load without requiring manual assistance close to the load.
  • the sling may comprise several branches. For long and narrow loads, two branches may be sufficient, but for wider loads, three or four branches may be needed for stability.
  • the guide comprises a multiple of elongate members extending generally upwards and outwards from the load to form a general funnel-shape. This allows the branches of the sling to fall between the elongate members and thereby not interfere with the load connector or the lifting unit. It also reduces the wind load as compared to a continuous funnel.
  • the elongate members are attached to a central member, said central member in turn being attached to the load. This allows for a more convenient attachment of the guide to the load as a single unit.
  • the central member is attached to the load by a multiple of straps, said straps being attached at one end to spaced apart locations on the load, and said straps extending tightly from said locations to said central member.
  • the guiding device may be disconnectedly attached to the load via a coupling member that is fixedly attached to the load, such as a bayonet-type coupling or similar. This also gives the possibility of removing the guiding device when not needed, and also makes the process of removal and refitting easier.
  • the elongate members are flexibly attached to said central member so that they can flex without breaking if impacted by an object, such as another load.
  • the central member has a raised portion that acts to prevent portions of said sling settling on said central member thereby any sling chain or wire will slide off the raised portion and not hinder proper contact between the load connector and the seat of the load connector.
  • the central member has a seat for receiving said load connector and that said load connector has a corresponding feature adapted to mate with the seat on said central member.
  • the sling is equipped with elastic members attached to each branch for pulling the sling branches away from the load connector in order to prevent pile-up of sling material within the guiding device. Thereby it is ensured that sling chain or wire will not interfere with the load connector or lifting unit.
  • the load connector has a loop and a footplate, the load connector being adapted to receive a top link of a sling, so that the loop extends through the top link and the top link rests on said footplate.
