Definitions

  • the invention relates to a shipping container comprising: - a plurality of walls that form, in use, at least a floor wall, and a plurality of side walls of the shipping container, and - a frame for mechanically fixing at least one of the side walls and the floor wall thereto.
  • the invention also relates to a lashing eye.
  • the invention further relates to an assembly for assembling a shipping container.
  • the invention also provides use of a lashing eye of a shipping container.
  • the invention further provides a method of assembling a lashing eye to a frame for a shipping container.
  • Shipping containers are often used for transport of goods over sea or land. Cargo ships can be loaded with many shipping containers. In a harbour, these shipping containers can be transferred to e.g. trucks, inland navigation vessels, and/or naval vessels. During such transfer, a hoisting crane may be used for lifting the shipping containers from the ship and depositing the shipping containers on land, on a truck, or on another ship.
  • shipping containers may be stacked on top of each other.
  • a shipping container may therefore experience a substantial load from other shipping containers that are present on top of said shipping container.
  • significant stresses may be experienced by the shipping container.
  • known shipping containers are usually made of corrugated steel. Steel walls of the known shipping containers are strong enough to be able to withstand these loads.
  • known steel shipping containers also have disadvantages.
  • One of these is that such shipping containers are relatively heavy. Shipping containers may be filled with goods which may form a significant part of the total weight of a filled shipping container.
  • a known steel shipping container itself usually forms a significant part of said total weight as well.
  • a relatively large weight of the shipping container introduces various possible problems. It may for example increase fuel costs during transport of the shipping container over sea, land, or rail, or may limit an amount of shipping containers placed on a ship.
  • a shipping container may be handled several times from the moment of loading goods into the shipping container until the moment of unloading said goods at the final destination of the shipping container.
  • the shipping container might be tilted.
  • other lateral forces might build up during acceleration or de-acceleration. Therefore, the goods usually need to be fixed against shifting and tumbling. In this way, a probability for damage to the goods may be reduced.
  • a probability of a shift of a central point of gravity of the shipping container caused by moving goods inside the shipping container may be reduced.
  • Such a shift may cause unsafe situations during shipping container handling like hoisting and other transport movements of the shipping container. Therefore, shipping containers usually comprise lashing eyes to which e.g. a rope can be connected. By means of said rope, a load can be tightened inside the shipping container. The fixing of the goods inside the shipping container by means of lashing eyes has therefore become a standard practice in the shipping container transport industry.
  • such lashing eyes may be welded to a wall of the shipping container. Then, the lashing eyes may be connected to a corrugate steel side wall, in particular to an inner side of an outwardly projecting corrugation, so that the lashing eyes do not limit a space for moving pallets and boxes into and out of the shipping container.
  • a side wall comprising a fiber-reinforced material usually lacks such corrugations. Then, fixing lashing eyes inside the shipping container without compromising said space for moving pallets and boxes into and out of the shipping container, may become problematic.
  • the invention provides a shipping container, preferably a composite shipping container, comprising a plurality of walls that form, in use, at least a floor wall and a plurality of side walls of the shipping container, and comprising a frame for mechanically fixing at least one of the walls thereto, wherein the at least one of the walls comprises a fiber-reinforced composite wall material, in particular a fiber-reinforced plastic wall material, wherein the shipping container is provided with a lashing eye that is fastened to the frame of the shipping container, and wherein the at least one of the walls is provided with a cavity for receiving therein at least part of the lashing eye.
  • a shipping container preferably a composite shipping container, comprising a plurality of walls that form, in use, at least a floor wall and a plurality of side walls of the shipping container, and comprising a frame for mechanically fixing at least one of the walls thereto, wherein the at least one of the walls comprises a fiber-reinforced composite wall material, in particular a fiber-rein
  • the at least one of the walls preferably comprises a laminate structure comprising two, preferably outer, laminate layers, wherein at least one, preferably both, of said laminate layers are, at least partly, formed by a fiber-reinforced composite wall material.
  • the laminate structure further comprises a core layer arranged in between, and in mechanical load transferring contact with, the laminate layers, said core layer in use supporting the laminate layers.
  • a strength of the at least one of the walls comprising the fibre-reinforced composite wall material may benefit from a relative large wall thickness.
  • a distance between the laminate layers is maximised. Maximisation of said distance may be limited by standardised dimensions of the shipping container, e.g. according to ISO norms.
  • an inner surface of the at least one of the walls may be flat instead of corrugated. Such may be desirable for having a relatively strong wall.
  • a lashing eye can be combined with the at least one side wall comprising the laminate structure.
  • the cavity may enable placing the lashing eye outside a space for moving pallets and boxes into and out of the shipping container.
  • a space inside the shipping container for moving pallets and boxes into and out of the shipping container may at least partly be prevented.
  • the at least one of the walls bounds an inner space of the shipping container, wherein the lashing eye and the cavity are dimensioned so that the at least part of the lashing eye can be received in the cavity without having the lashing eye project out of the cavity into the inner space of the shipping container.
  • the at least one of the walls has an inner surface that faces an inner space of the shipping container and extends substantially in a wall plane, the wall plane bounding the inner space of the shipping container and extending over the cavity.
  • the lashing eye and the cavity are dimensioned so that the at least part of the lashing eye can be received in the cavity without having the lashing eye project through the wall plane into the inner space of the shipping container.
  • the plurality of walls further form, in use, a top wall of the shipping container, wherein the at least one of the side walls extends from the lower side rib in the side wall direction towards the top wall.
  • the lashing eye is fastened movably to the frame of the shipping container. Moving the lashing eye may enable removing the lashing eye out of, or into, an inner space of the shipping container. As a result, when moved out of the inner space, loading goods into or out of the shipping container may be unhindered by the lashing eye. When the lashing eye is moved into the inner space, the lashing eye may be used for connecting a rope thereto for tightening goods loaded in the inner space of the shipping container. In an embodiment, the lashing eye is movable from a retracted position to an extracted position and vice versa.
  • the at least part of the lashing eye is received in the cavity so that the lashing eye lacks projection into the inner space of the shipping container.
  • the lashing eye and the cavity are dimensioned so that the at least part of the lashing eye, when in the retracted position, is received in the cavity without having the lashing eye project through the wall plane into the inner space of the shipping container.
