Definitions

  • a carrier device for moving containers or other articles comprising a bifurcated vehicle having arms for extending along each side of the article to be raised and lifting means vertically movably mounted on the arms adapted to raise the article so that it can be moved with the vehicle.
  • the arms are supported by wheels and as the lifting means are carried by the arms the height of the device can be kept within or near the height of the raised article.
  • This invention relates to carrier devices and is more particularly directed to a carrier device for moving containers or other articles.
  • Carrier devices for moving heavy articles are well known which straddle the article and then lift it to a raised position so that the article can be moved with the vehicle.
  • a disadvantage with such known devices is that the operating mechanism must necessarily be higher than the article to be lifted and in certain circumstances this can be an embarrassment, especially if the article is to be used in confined spaces such as on board ships or other transport vehicles or in warehouses.
  • a carrier device for moving containers or other articles comprises a bifurcated vehicle having arms for extending along each side of the article to be raised and lifting means carried by the arms adapted to raise the article so that it can be moved with the vehicle.
  • the height of the device can be kept low enough to enable it to work in spaces which are only a little higher than the article itself when in the raised position.
  • the arms of the bifurcated vehicle are supported on wheels so that the load on them is carried directly to the supporting surface.
  • the lifting means includes a pair of lifting devices one of which is mounted on each arm and means for operating the devices in synchronism.
  • the pair of lifting devices are arranged at or towards the outer ends of the arms and a further pair of lifting devices are provided at or towards the inner ends of the arms, means being provided to operate the devices in synchronism.
  • each corner of, for example, a container can be acted upon by an individual lifting device and with articles such as containers, the appropriate lifting provisions can be utilised.
  • a lifting frame is provided between the arms to which the article to be raised is connected and means may be included for causing the lifting frame to be raised to a position in which it is above the lifting devices themselves.
  • the lifting frame has downwardly projecting extensions which are connected to the lifting devices, and the downwardly projection extensions can also act as guides to locate the frame in relation to the arms on the vehicle.
  • each pair of lifting devices may be connected together by transverse lifting members which are raised by the lifting devices and which raise the lifting frame.
  • This arrangement is particularly useful for extra heavy duty loads but is of course slightly higher when carrying the article because of the transverse members above the lifting frame.
  • the flexible member may be in the form of a chain or cable arranged to pass over a wheel carried on the upper end of the vertically moveable member.
  • Means may be included for compensating for the load between the lifting devices if the container or article is unbalanced and when fluid operated rams are used compensating means may be included to ensure that the rams move in unison in spite of the possible disparity in ram pressures.
  • the compensating means may include a coupling to each ram which transmits the amount :of movement thereof to a compensating control valve which controls fluid flow to the rams concerned.
  • Each coupling may include a rack which acts on one side of a pinion, the other side of which is also contacted by a rack coupled to another ram and the pinion being carried by a lever so that out of phase movement of the racks will cause movement of the lever which is connected to the compensating control valve.
  • FIGURE 1 is a side elevation of a carrier device according to the invention
  • FIGURE 2 is an end elevation of the device shown in FIGURE 1,
  • FIGURE 3 is an end elevation of an alternative construction
  • FIGURE 4 is a diagrammatic view of part of the hydraulic control circuit.
  • FIGURE 5 is a pictorial view of an arrangement as shown in FIGURES l and 2 in use.
  • the carrier device is in the form of a trailer vehicle having a lower frame comprising a pair of horizontally displaced heavily constructed arms 1 which are joined at one end by a connecting portion 2 which is of similar heavy construction.
  • the other ends of the arms 1 are spaced but not connected by an transverse member, this construction providing the bifurcated vehicle previously referred to.
  • Each of the arms 1 carries a road wheel 3 towards its outer end and the connecting portion 2 is provided with a support device in the form of a heavily constructed downwardly extending frame 4 so that when the trailer is not in use it will rest in a subtantia'lly horizontal position.
  • the towing end of the trailer is provided with a tow bar 5 and towing pin 6 and plate 7 to co-operate with a fifth wheel plate 8 carried on a tractor vehicle 9 as shown in FIGURE 5.
  • the carrier device being described is for use with contaiuers and the dimensions of the arms 1 are thus arranged so that they can be passed along each side of a container indicated at 10 in FIGURE which is to be raised.
  • Each arm 1 carries two hydraulically operated rams 11, 12, 13, 14 which are mounted in support structures indicated at 15 which are carried adjacent each end of the arm concerned.
  • the support structure 15 at the outer end of the arm 1 is arranged longitudinally of the arm beyond the supporting wheel 3.
  • Each support structure 15 comprises a mounting which carries the rams 11, 12, 13, 14 in a substantially vertical attitude and a channel section guide rail 16 which extends parallel to the ram in the inside of the arm 1.
  • Each ram cylinder 17 is arranged to be rigid with the arm 1 and the movable piston carries a vertically extending rod 18 the upper end of which carries a pulley wheel 19.
  • the wheel 19 is arranged so that it can pivot slightly about a vertical axis and can rotate about a substantially horizontal axis which is substantially parallel with the longitudinally extending direction of the arm 1 on which it is carried, and a heavy duty flexible element such as a roller chain 20 is passed over the pulley, one end 21 being rigidly secured to the ram support 15.
  • the other end of the chain, on the inside of the arm 1 is connected to a lifting frame 22 as set forth in more detail hereinafter.
  • the lifting frame 22 which is carried between the pulley wheels 19 on the side arms 1 is in the form of a cross braced upper frame portion 23, the corners of which carry twist-lock connection arrangements 24 of known for engaging the appropriate twist-lock connections on the upper end of the corners of a container 10.
  • Downwardly projecting extensions are fixed to each corner of the lifting frame 22 and are in the form of channel section legs 25 which co-operate with the channel section guides 16 on the inside of the arms and thus act to locate the frame 22 against longitudinal and transverse movement within the arms 1 themselves.
  • the dimensions of the rams and the downwardly extending legs are arranged so that when the container is raised from the ground and the device is in a mobile form the lifting frame is higher than the extended rams and pulleys and the only additional height to the container is that the thickness of the upper lifting frame itself as shown in FIGURES 1 and 2 and will be clearly seen in FIGURE 5.
  • the container can now be moved as required and can, for example, be loaded onto another vehicle again as shown in FIGURE 5.
  • lifting frame could be provided with angled extensions as shown in broken lines at 27 in FIGURE 1.
  • twist-lock arrangements could again be provided and the shaped lifting frame could thus be used with containers of two different sizes. It would of course be necessary to provide the required clearance for the container between the arms 1, 1 adjacent the connecting portion 2.
  • compensating means are provided to ensure uniform elevation of each ram 11, 12, 13, 14 in spite of disparity in ram pressures and the four hydraulic rams are thus connected by a signalling system as shown in FIGURE 4 so that three of the rams 11, 13, 14 are caused to follow the displacement of the remaining one 12 by employing the established principle of mechanical position feed back in the sense that the master ram 12 can be caused to displace as an open loop device with the remaining three rams 11, 13, 14 acting as position servo mechanisms which move in correspondence with the displacement of the master ram.
  • each servo-control valve 28, 29, 30 is operated by means of a centrally pivoted lever indicated diagrammatically at 32 one end 33 of which is connected to the valve spool (not shown) and the other end of which carries a sprocket 34 arranged between a pair of roller chains indicated diagrammatically at 35 which thus act as racks.
  • the opposite displaced ends of the chains are connected to cables 36 which pass around pulleys 37 carried by the connecting rods of pneumatic cylinders 38 and the other ends of the chains 35 are connected to 5 cwt.
  • the arrangement as set forth is provided between each of the rams on each arm 1 and also between the pairs of rams on the opposite arms thus ensuring that the container is not tipped in any direction when the rams are operated.
  • the cables 39 pulleys 40 and connections 41 are shown in FIGURE 1 but the remainder of the compensating mechanism is enclosed within the casing on each arm 1 indicated at 50 into which pass the various pressure fluid lines indicated at 51 the connection to the tractor vehicle being at 52.
  • FIGURE 4 the main pressure fluid supply line is indicated at 42 and the main relief line at 43. It will be seen that the servo valves 28, 29, 30 and the main control valve 31 can switch pressure fluid from the line 42 to the appropriate side of the piston 44 of each of the rams by the lines 45, 46 connecting the other side appropriately to relieve line 43.
  • the line 45 provides the pressure fluid when the ram is used to raise the load, and controlled locking valves 47 which are in the form of pilot operated check valves are provided in each of these lines so that the rams can be locked in their raised positions.
  • These locking valves 47 are connected by pilot lines 76 to a solenoid operated valve 48 so that the lock valves allow free movement of the rams when raising and also when lowering provided the pilot lines 76 are energised by the valve 48.
  • the electrical connection is however in parallel with the electrical circuit for the control valve 31, and when the energising signal is removed when neither the raise not lower position is selected the lock valves 47 are shut thus sustaining the positions of the rams irrespective of load.
  • the broken lines 49 indicate drain lines from the valves 47.
  • pressure fluid lines 53, 54 which carry hydraulic fluid to and from the twist-lock mechanism are provided on the lifting frame which is also operated by an electrically controlled valve 55 of known kind. If desired an indicator lamp system can be included which indicates when all the twist-lock mechanisms are engaged in known fashion, and a pivoted link 56 is provided between the arm 1 and the lifting frame 22 to carry the lines 53, 54 up to the frame under control as shown in FIGURE 1.
  • a castering wheel 57 can be arranged on each arm 1 on a hydraulically actuated retractable support 58, the operating fluid being supplied through pipe lines 59, 60 indicated on FIGURE 4, the control again being through a solenoid operated valve 61. These casters can therefore be lowered When the carrier device is not in use and it is desired to move it bodily sideways.
  • a pneumatic and spring brake 62 is provided on each of the wheels 3 the power of operation again being provided by the tractor vehicle 9.
  • FIGURE 3 In an alternative arrangement shown in FIGURE 3 the same reference numerals are used to indicate similar parts but this particular device is intended for use with heavier containers and is therefore more strongly constructed.
  • the ram supports 65 are higher in this construction and the arm piston rods 66 project directly from the upper end of the supports 65.
  • Each of the piston rods 66 is fastened to a transversely extending cross member 67, two such cross members being provided one for each oppositely opposed pair of rams and these cross members 67 themselves are connected lengthways so that an upper frame, indicated generally at 68 is formed.
  • Each of the cross members 67 carries a pair of pulley wheels indicated at 69 around which are again wrapped lifting chains 70.
  • One end 71, of each lifting chain is securely fastened to the appropriate ram support 65 and the other end of each chain is secured at 72 to a lifting frame 73.
  • each corner of the lifting frame 73 is thus connected to a chain 70 and the frame 73 is again provided with the usual twistlock connections to again engage a container, in this case indicated in broken lines at 74.
  • This kind of construction is suitable for containers up to 40 tons and if required a further stiffening cross member 75 can be included which extends transversely across the device at the towing end to further stiffen the supports 65.
  • guides can again be provided at the sides to prevent the container moving longitudinally or transversely when it has been raised.
  • the device can of course also be used with other articles besides containers, appropriate means for connecting the articles to be lifted to the frame being provided. Again, in certain circumstances the frame itself may not be required, the chains 70 carrying attachments to connect them directly to the article to be raised.
  • the carrier device is provided as a trailer for use with a tractor vehicle but it may be convenient to incorporate it in a prime mover, the driving position and steerable wheels being provided at the closed end of the bifurcated chassis.
