Definitions

• the present invention relates to a movable load carrier, e. g. for loads like containers and container platformscomp ⁇ rising a generally U-shaped frame the parallel arms respec ⁇ tively of which are provided with wheels with a shaft across said arm, the frame being able to pivot about said shaft in a vertical plane, means associated with said frame for flexible connection with the lifting device of a vehicle, e. g.
• a fork truck and a first and a second set of connecting means for connecting said load carrier with said load, the load carrier being intended to be moved by said vehicle with its open frame portion facing said load and enclosing said load on three sides with a clearance between said frame and the sides of said load, said first set of connecting means being at first connected with a front end portion of said load, whereupon said second set of connecting means is connected with the rear end portion of said load.
• each of said connecting means consists of a sliding bolt supported slidably in the direction of the container side on the frame for contacting one end of said sliding bolt with an arbitrary flat supporting surface on said container, a chain secured on the opposite end of said sliding bolt, and a locking means secured on the opposite end of said chain for lockable engagement with a recess in the lower corner portion of said container, the length of the chain being adapted for the sliding bolt to tension said chain when lifted and, thus, urged against said contai ⁇ ner by said chain.
• Said locking means may consist of a bayonet catch.
• the object of the present invention is, thus, to provide a movable load carrier that is especially suited for quay structures and other loading areas where the available ve ⁇ hicles have low lifting capacity and no downward thrust.
• the movable load carrier mentioned above is characterized in that said second set of connecting means have their upper end extending from a tur ⁇ ret structure generally located above said wheels, a member, e.g. a hook, being provided at the lower end of said connect ⁇ ing means and intended for engagement with said load, and that said frame arms have a length substantially smaller than the total length of the load.
• Figures 1 and 2 show a side elevation and a plan view respec ⁇ tively of a first embodiment of the load carrier according to the invention.
• Figures 3 and 4 show a side elevation and a plan view respec ⁇ tively of a second embodiment of the load carrier according to the invention.
• Figures 5, 6, 7, and 8 illustrate how the load carrier according to the invention is connected with a container.
• Figures 9 and 10 illustrate in a side elevation and a plan view respectively a load carrier according to Figures 1 and 2 with a mounted container of one length and a container of another length.
• Figures 11, 12, and 13 show more detaled portions XI, XII, and XIII of Figure 2.
• Figure 14 shows the load carrier according to the invention being moved by a fork truck to enclose a container. . -PAIP
• the load carrier according to the present inven ⁇ tion is especially described below in connection with a container load, it will be understood that the load carrier is gually suited for container platforms as well as for transporting bundled timber, long beam and tube structures as well as other heavy structures that are difficult to mo ⁇ ve because of their weight and dimensions, e.g. on a quay structure where said load has been unloaded from a ship and where there are no lifting tools, e.g. fork trucks able to service more than e.g. 20% of the load capacities necessary to move the load.
• the mode of operation of the load carrier requires a shortes possible length of structure as the main weight of the load, i.e. 80 -90%, is to be transfered to the supporting wheels 2 of the load carrier.
• the load carrier comprises a main frame 1,generally U-shaped. Said wheels 2 are provided at the open end portion of said frame at each arm. Above the wheels 2 a turret 9 is mounted and is via an adjustable mounting support 11 connected with connecting means 10 in the shape of a chain or a wire having an engaging hook 23 provided at its lower end.
• a leading pulley 18 is provided for the chain on top of said turret as well as a hydraulic jack for tension- ing said chain, resulting in a lifting movement of the con ⁇ tainer when the lifting force is transfered to the top of the load carrier turret.
• cross beam 5 Between the parallel boundaries of frame 1 a cross beam 5 has been located, the ends of which are slidably connected with said parallel boundaries by slide bearings 6.
• guide sockets 8 are mounted on which elongated supporting pins 7 are secured and intend ⁇ ed for engagement with corresponding securing recesses in the lower front portion of the container.
• Guide sockets 8 cause the supporting pins to be inserted into said recesses at a correct level.
• the ends of said supporting pins may comprise an upright portion 25, e.g. a bead or a portion of said pin extended upward. Said bead may possibly be of a replaceable kind.
• said supporting pin may be replaceable.
• said sup ⁇ porting pin When said sup ⁇ porting pin is inserted in the oval securing recess in the container it will not abut directly angainst the rims of said securing recess. This will not be the case before the instant when supporting pin 7 is lifted when the front port ⁇ ion of the load carrier is lifted.
• the upright portion will, thus, be located behind and on the upper side of securing recess and. prevent the supporting pin from slipping out when the container has no full contact with the ground.
• the pre ⁇ sent load carrier is suited for several container sizes.
• the broken lines show said load carrier used for a container size e.g. 10'
• the full lines show the load carrier used for a container size 20' or 23'.
• a front pair 14 and a rear pair 13 of locking blocks respectively are provided, and on each of the slide bearings 6 a pivotally mounted locking hook 12 is provided intended for engagement with said locking blocks, as shown in the drawings.
• a frame rod 4 is firmly attached to the center point of the cross beam 5 which, thus, forms a pull rod for the load carrier.
• said frame rod 4 may be slidably connected with the frame 1 by guides 25 and 26 secured to the frame.
• guide 25 is provided on a cross piece I' of the U-shaped frame.
• connection link 3 form a direct extension of a pipe inside frame rod 4.
• Said two telescopic members may be locked to ⁇ gether by a locking bolt 17.
• locking bolt 17 only serves to lock connecting link 3.
• a supporting foot 15 is provided which can advantageously be used when said load carrier with an attached load, e.g. in the shape of a con ⁇ tainer, is disengaged from the lifting unit, as shown in Figure 8.
• a fork truck 20 is used for mani ⁇ pulating the load carrier, said truck having forks 22 pro ⁇ vided in a conventional manner on its lifting member.
• a fixing device 4 ( Figure 13) forms the connection between the lifting tool and said connecting link 3. Said fixing device is selectively adaptable to the dimensions of the lifting tool and may be secured to said tool in a simple manner.
• the load carrier will have an initial position as shown in Figure 1 or 8, the front portion of the load carrier being supported by foot 15.
• the fork truck is connected and the longitudinal dimension of the load carrier is adjusted for one of the desired container sizes as regards the posi ⁇ tion of cross bar 5 and the length of frame rod 4.
• the supporting foot 15 is locked in its upper position.
• the load carrier is then maneuvered inward along the sides of con ⁇ tainer 21 with guide sockets 8 along the ground, as appears from Figure 5.
• cross bar 5 of the load carrier abuts the container wall the lifting function of the fork truck &- REA
• OMPI is activated and the container is lifted by supporting pins 7 engaged with its front end.
• the container is placed in a tilted position, as shown in Figure 6, whereupon the en ⁇ gaging hook 23 of chain 10 is inserted in the lower rear securing recess of the container. It is ensured that the chain length is correctly adapted by the aid of the adjust ⁇ able mounting support 11 or 18 and 19 respectively, see Fi ⁇ gure 7, and the load carrier is now lowered into a transport position by force of gravity. The main portion of the total load is, thus, transfered to the supporting wheels 2 of the load carrier. To remove the load the described sequence is reversed. If the embodiment with an adjustable mounting sup ⁇ port, shown in Figures 3 and 4, is chosen, i.e.
• the correct length of the chain should be secured e.g. adjustably by a catching hook on the piston rod.
• a supply from the oil feed to the lifting cylinder of the truck it will then be possible to feed pressure oil in parallel to said two jacks 19 via a stop valve and a hydraulic connection (not shown) , and possibly in parallel with the lifting cylinders of the truck as well.
• the truck now seeks to lift the load carrier, the same oil pres ⁇ sure is transfered to the cylinders of the hydraulic jacks 19 on the load carrier.
• the stop valve for the two load carrier cy ⁇ linders is closed, and the load carrier is lowered to a de ⁇ sired moving position.
• the stop valve is opened and the load is lowered.
• the load carrier is reversed with its catching hooks still connected with the container and the hydraulics of the truck in a lowering position, until the hydraulic cylinders 19 have reached their extended end positions.
• the load carrier is excellent for use in loading/unloading areas having a low capacity and it may also be modified for heavier loads.
• the load carrier may be produced as an equipment to be assembled on location by bolting the parts together.
• the solution comprising a hydraulic jack in connection with chain 10 is especially suited for small fork trucks and large loads.
• the connecting link 3 i cooperation with the extendable frame rod 4 is especially intended to ensure an
• connection link is extendable it is locked as mentioned in an extended and a contracted position resp. by locking bolts 17.
• the connection between fixing device 24 and connecting link 3 may be achieved by a ball head bearing known per se. ic As indicated in claim 14, said ball head bearing is prefer ⁇ ably situated beneath the forks of the fork truck, so that said forks are not hampered by them when the connection link of the load carrier is lifted, and neither in transport condition as illustrated in Figure 8.
• the present load carrier is not limited to utilization in connection with a fork truck.
• Other vehicles comprising a loading tool, e.g. a tractor, a transfer truck or the like may be used as well. 5
