Definitions

  • the shipping industry employs the use of large cargo containers to transport cargo shipped from one location to another. These containers can be easily and conveniently loaded and unloaded, and moved from one transport vehicle or vessel to another for transport across land and/or sea. In this manner, goods traveling to a common destination can be easily moved in large quantities to reduce the amount of time required for loading and unloading the transport vessels.
  • the cargo containers in use today have largely become standardized in dimension and structural, and are such that they can be easily, conveniently and securely stacked vertically in a side by side and end to end relationship to maximize the use of hold and deck space on ships and the like, on which such containers are placed.
  • collapsible cargo containers require an apparatus called a "spreader” to lift the cargo containers from loading platforms to ships, trains, and the like, and from ships, trains, etc. to the loading platforms.
  • These spreaders are large crane structures with interlocking mechanisms to grip or engage the cargo containers for lifting from one location to another, and to prevent them from tilting or dropping during the transfer operation.
  • Spreaders are typically utilized at shipping ports, train stations, etc. where large numbers of containers are handled on a daily basis. Some are designed to lift containers of a specific length, while others are adjustable to accommodate various sized containers.
  • Spreaders are suspended from cranes via a head block or cables, which can be used to lower the spreader onto the roof of a container for engagement of the locking mechanisms.
  • spreaders typically engage four upper corner fittings of the shipping container, locking the spreader to the container so that it can be safely lifted. While such spreaders are ubiquitous in the shipping industry, they are predominantly configured for standard cargo containers and therefore cannot collapse the new type of collapsible cargo container developed by the present inventors. Accordingly, as these new collapsible cargo containers work their way into the shipping industry the need for specialized spreaders will also be needed.
  • the present invention is a variation of a cargo container lifting device known as "spreader" which is used to lift cargo shipping containers used for transporting goods via ship, rail and truck, and method for using same.
  • the spreader described herein differs from all other spreaders in that it is designed to assist in the folding of a unique collapsible container described in a related provisional patent application.
  • the purpose of such a spreader is to help automate the collapsing and unfolding procedure, as well as to simplify the design of the container, thus reducing its cost by integrating motors, actuators, levers, etc. into the spreader instead of into each container.
  • the roof and several other parts of the container are sectioned, and the near-side walls of the container have been removed for clarity.
  • the container is viewed looking up from below ground level to reveal relevant details inside the container, but would in actually be resting on a supporting platform such as the ground, another container, a truck chassis, etc. during the container folding/unfolding procedure.
  • Figure 1 illustrates a perspective view of the spreader of the present invention positioned above a cargo container
  • Figure 2 illustrates a perspective view of the spreader of the present invention engaged with a top of a cargo container
  • Figure 3 illustrates a perspective view of the spreader of the present invention with pivoting arm positioned against cargo container door;
  • Figure 4 illustrates a perspective view of the spreader of the present invention with cargo doors rotated upwards as part of collapsing sequence
  • Figure 5 illustrates a perspective view of the spreader of the present invention with cargo doors rotated against cargo container ceiling as part of collapsing sequence
  • Figure 6 illustrates a perspective view of the spreader of the present invention with the pivoting arms rotated back to a neutral position
  • Figure 7 illustrates a perspective view of the spreader of the present invention with the side walls of the cargo container collapsing as part of collapsing sequence
  • Figure 8 illustrates a perspective view of the spreader of the present invention above a fully collapsed cargo container ceiling
  • Figure 9 illustrates a perspective view of the spreader of the present invention positioned over a collapsed cargo container
  • Figure 10 illustrates a perspective view of a second preferred embodiment of a spreader of the present invention positioned on top of a cargo container
  • Figure 11 illustrates a perspective view of the spreader of Fig. 10 positioned over a collapsed cargo container.
  • Figure 1 shows a first preferred embodiment of a spreader 1 positioned above a new collapsible container 2. Shown below the spreader in Fig. 1 is a collapsible container (shown with a front half omitted to illustrate the interior structure) such as that set forth in U.S. Patent Application Serial No. 11/792,161, the contents of which is fully incorporated herein by reference.
  • the spreader 1 would be lifted by a modified standard fork lift using a head block or a plurality of lifting cables.
  • the spreader 1 may have multiple lifting eyes (not shown) positioned at the corners to resist rotation of the suspended container 2, or may have attachment points for other guidance devices or cables.
  • a forklift can also be used to carry the spreader, suspended by short mechanical links instead of cables. Simplified representations of industry-standard twist locks 5 are shown.
  • the frame 4 is formed from a steel I-beam 19 having cross beams 20 and longitudinal reinforcing members 21.
  • the rigid steel beams and members that cooperate to form the frame 4 should be constructed of a high strength steel having low corrosion properties to operating in coastal climates.
  • the I-beam 19 includes transverse end members 22, which cooperate with the longitudinal reinforcing members 21 to form a rigid structure.
  • Mounted to the transverse end members 22 at each outer surface is a vertical guide flipper 26 that encloses the top of the collapsible container 2 and assists in maintaining a vertical reduction of the container without unwanted tilt or lean.
  • Each vertical guide flipper 26 includes a flared tip gather guide-portion 28 that funnels or guides the outer edge of the container's upper surface into position against the spreader's frame 4.
  • a pusher assembly 7 (shown only on left side for simplicity in drawings) having left and right arms 17 pivotally mounted to the frame 4.
  • the pusher assembly 7 is preferably driven by a hydraulic engine mounted on the spreader 1 (not shown), although other forms of motors or power systems are considered within the skill of the art.
  • a pusher bar 31 mounted between the two arms 17 includes a pair of rigid vertical struts 33 having angled lower edges for engaging the cargo container's door and end walls in a flush manner. As explained below, as the hydraulic engine drives the pusher assembly about the pivot pin 51, the rotation of the arms 17 and the pusher bar 31 cause the ends 37 of the vertical struts 33 to engage and rotate the. end wall and doors of the collapsible cargo container.
  • Figure 2 shows the spreader 1 resting on the upper wall or ceiling 12 of the container 2, with the twist locks 5 engaged at the corner fittings 6.
  • the two pusher assemblies 7 at respective ends of the spreader 1 pivot about pins 51 mounted to the spreader's frame 4.
  • Only the left pusher assembly 7 is shown in the figures, although there would be a corresponding assembly on the right hand side of the spreader 1 that operates in a similar manner for rotating the opposing end wall 39.
  • Figure 3 shows the struts 33 of the pusher assembly 7 after it has rotated into contact with the doors 8 of the container 2. Contact is made via pads 10 on the struts 33, where the pads 10 may make contact with either the door 8 or the adjacent door aperture frame 11 that supports the doors 8, and to which the doors are attached on their outermost edges via hinges.
  • a releasable locking mechanism (not shown) may be employed to secure the struts 33 either to the doors 8 or to the door aperture frame 11, or to both at pads 10.
  • An actuator on the spreader 1 releases a mechanism within the door aperture frame 11 that keeps it locked in the upright position as shown.
  • Figure 4 shows the spreader collapsing the container at the door aperture frame 11 and doors 8 as they are transitioned from their vertical orientation to a position pushed up into the roof 12 by the rotation of the pusher assembly 7, after release of the retention mechanism. Note that only the left hand side of the door and frame, and end wall, are shown to better illustrate the interaction of the spreader 1 with the container 2. A similar pusher assembly 7 on the opposite end of the spreader 1 would serve to act on the end wall 9 of the container 2 in the same manner.
  • Figure 5 shows the doors 8 and end wall 9 pushed fully against the roof 12 of the container 2 by extended rotation of the pusher assembly 7. Up locks 13 on the ceiling of the cargo container hold the doors 8 and front wall 9 in the stowed position. With the end wall 9 and the doors/door frame cleared, the spreader initiates the folding of the side walls 14 of the container 2 from their vertical position to their horizontal position. Once the door 8 and end walls 9 are secure, as shown in Figure 6, the pusher assembly 7 retracts out of the cargo container's interior after the pads 10 have disengaged from doors 8 or frame 11.
  • Figure 7 shows the spreader 1 lowering toward the ground as the container side walls 14 beginning to fold into two separate halves.
  • the cargo contain may incorporate a release such that once the doors and end wall are mounted to the ceiling in the stowed away position, the side walls 14 may be allowed to collapse.
  • the spreader may include separate pusher assemblies like those described previously that initiated the folding operation by acting on the side walls 14 to apply an inwardly directed force. This force helps to buckle the two halves of the side walls 14 and begin the collapsing of the walls from their initial vertical state. Once the side walls begin to fold, the spreader 1 can complete the collapsing process as the ceiling weighted with the additional mass of the door and end wall force the side walls into their respective horizontal positions.
  • Figure 8 shows the spreader above the fully collapsed container.
  • Figure 9 shows the container 2 and spreader 1 as viewed from the other side, after the spreader 1 has unlocked from the container and has been lifted away. From this view, closure clamps 15 can be seen, which keep the container 2 in the collapsed state should it be lifted from above. The closure clamps 15 can be released by extensions of the spreader 1 to automate unfolding process. Unfolding the container is essentially the reverse of the previously described procedure, except that closure clamps 15 and up locks 13 need to be released as necessary by actuators mounted to the sides of the spreader via brackets 16.
  • the spreader may preferably include a self-contained hydraulic system to operate the various mechanisms, so that the only connection which has to be made (besides mechanical) when engaging the new spreader is electrical.
  • An electrical cable (not shown) with a multi-pin electrical connector on the new spreader would connect to the existing spreader, which would need to have an electrical junction box added to receive the connector.
  • the cable provides electrical power to operate the hydraulics on the new spreader, and also relays control signals between the new spreader and the operator in the crane or other lifting equipment who would have an auxiliary control panel.
  • the new spreader is designed to expand and contract to fold containers of 20-foot, 40-foot and 45-foot standard lengths, as well container sizes both greater and smaller.

Abstract

L'invention concerne un appareil et un procédé pour lever et démonter un conteneur de transport démontable, lequel appareil comporte un châssis et des dispositifs de guidage verticaux permettant d'aligner le palonnier avec le conteneur de transport. Des premier et second éléments poussoirs agissent sur les parois d'extrémité du conteneur pour les faire pivoter contre le plafond du conteneur, des systèmes de verrouillage retenant les parois d'extrémité en position repliée. Des parois latérales pliantes sont ensuite déformées par le poids du plafond avec l'aide du palonnier, jusqu'à ce que lesdites parois latérales occupent une position principalement horizontale entre la combinaison plafond/paroi d'extrémité et un plancher du conteneur de transport, formant ainsi une configuration compacte. Le palonnier déplie le conteneur en suivant les étapes susmentionnées dans un ordre inverse.
