Description
SPECIFICATION
Grappler system for lifting apparatus
This invention relates in general to a lifting apparatus and, in particular, to an apparatus for lifting and transporting a plurality of large containers.
More specifically, but without restriction to the particular use which is shown and described, this invention relates to a lifting apparatus having a grappler system to secure a stack of containers for lifting and transporting. The apparatus of the invention is capable of accommodating a stack of number of containers having a height greater than the height of the crane. The grappler system is adapted to engage the lower two containers in the stack in a manner, such that the bottom container may be released, while maintaining support of the containers above the released one.
In the transportation industry, certain types of containers have been developed, which are sometimes referred to as "intermodal" systems. Such trailers form unitized containers fitted to be interchanged between a truck, in which it forms a trailer therefor, and a ship or railfroad car. The design of such containers has evolved into wellknown standardized forms, such as IASO or Matson containers and the like. Each of these containers employ corner castings at each upper and lower corner to define sixteen apertures, which have been heretofore selectively engaged by such components as hooks or pins and the like for lifting the container.A typical gantry crane engages suitable holes in the corner casting and lifts a container, after it is removed from a train or ship, for example, and transports the container to a storage area, or directly to a truck, or alternatively, from the storage area to a truck and so forth. The conventional designs for such gantry cranes are only capable of lifting a single container at a time and cannot accommodate the lifting and transporting of a plurality of containers in a stack for efficiency of operation.
Because of space limitations, transporting schedules and considerations of economy, it is conventional for several transit containers to be stacked together in a storage area, for example, for a period during exchange between vehicles and/or vessels. As a result of design limitations of conventional cranes, it is only possible to move one container at a time to form such stacks. Moreover, existing cranes can carry only one container over a stack of three or four containers high, because no design in the prior art permits handling of containers above the top of the equipment. In view of the foregoing deficiencies, it is obvious that known cranes can only pick-up the top container of any given stack of limited height and must return to completely remove every item from a stack.
Known lifting equipment also suffer from limitations of operative versatility. For example, no cranes are available which can lift a stack of containers and release one of the containers as desired without interferring with the support of the remaining items. Prior apparatus are also designed so that the top beam or structure limits the height at which a container can be lifted over the stack, and thus, the number of items to be stored on top of each other.
It is, therefore, an object of this invention to provide an apparatus for lifting and transporting one or a plurality of containers in a stack.
Another object of this invention is to provide a lifting apparatus capable of engaging for support adjacent containers in a stack.
A further object of this invention is to provide a lifting apparatus capable of independently releasing the bottom container of a stack of items being lifted.
Still another object of this invention is to provide a lifting apparatus capable of supporting and lifting a stack of containers extending beyond the upper structure of the apparatus
Still further object of this invention is to provide a grappler system for a lifting apparatus capable of being adjusted to accommodate a range of sizes of containers being lifted.
These and other objects are attained in accordance with the present invention wherein there is provided an improved lifting apparatus having a grappler means adapted to lift the bottom pair of a stack of containers, such that optimum efficiency in the lifting and manipulating of stacks of containers is attained. The grappler system of the invention includes a plurality of engagement means to cooperate with selective holes of the corner castings conventionally provided in such large containers.
The engagement means selectively is capable of being inserted into the holes of the upper corners of a lower container and the lower holes of a container immediately above, such that the grappler system will support the stack of containers independently through engagement with two items.
This design permits the lower container to be independently released in a manner that the remaining stack of containers is still carried by the lifting apparatus for attaining increased versatility and manipulation of the stack, such as, for example, in a storage area or other location.
Further objects of the invention together with additional features contributing thereto and advantages accuring therefrom will be apparent from the following description of a preferred embodiment of the invention, which is shown in the accompanying drawings with like reference numerals indicating corresponding parts throughout, wherein::

Figure 7 is an end schematic view of the latching mechanism of Figure 6; and
Figure 8 is a top schematic view of one of the top container retaining assemblies of the lifting apparatus of Figure 1.
Referring now to Figure 1 there is illustrated an apparatus 2 of the invention capable of lifting and transporting one, or a stack of a plurality of large containers, such as used in the well-known "piggyback" applications. For purposes of illustration, apparatus 2 is shown in Figure 1 in operative contact to lift a stack of three containers 4. Generally, containers 4 are the type of large container, which may be placed on wheels and utilized as a trailer or truck, or may be placed on the bed of a railroad car, transported by ship or stored in stacked form in a loading area and the like.
Containers 4 are conventionally provided with corner devices or corner castings 4a, which provide holes to enable a crane and the like to lift and transport the containers from piace to place. Corner castings 4a are typically situated at each of the eight corners of the rectilinear container 4. As a result, the front and rear walls of containers each have four holes 4a situated at each corner, while the container side walls both have four holes at their respective corners.
Lifting apparatus 2 is in the form of a gantry crane having a two elongated horizontal lower beams 6, four upper beams 8 and four vertical corner beams 10 to create an inter-connected, opencentered frame work of the structure. The crane is mounted or supported by a typical wheel assembly
12 suitably affixed by brackets and the like to the lower beam 6 to permit the lifting apparatus 2 to be moved in a conventional manner by suitable power means (not shown). Thus, viewing Figure 1, it can be seen that the apparatus 2 can be maneuvered over a stack of containers 4 for lifting and transporting to another location as needed. Two of the upper beams 8 being laterally disposed in par
allel relationship to each other in a horizontal
plane, function as tracks upon which a movable
bridge 20 is carried for selective movement.The
platform 20 comprises a rectangular, open-centered structure defined by four inter-connecting
beams 22, such that the structure defines an open
ing 22a having a sufficient size to enable containers 4 to pass therethrough without interference with the bridge. This design of the apparatus 2
permits the lifting of a portion of the stack of containers 4 to a vertical position, above both the
beams 8 and the bridge 20.
The movable bridge 20 is provided with a pair of wheel assemblies 24 on each side in contact with the lateral upper beams 8 to permit movement of the bridge by a conventional technique (not
shown) in direction Z shown in Figure 1. As seen
in Figure 3, the bridge 20 may be oriented above the center one of three stacks of containers 4, or
above the end stacks, and the like. A pair of drum assemblies 26 are mounted on bridge 20 and include a respective pair of drums 26a mounted at each end of a power driven shaft 28 rotatably supported on brackets 28a about an axis extending substantially parailel to the direction of movement of the bridge relative to lateral beams 8.The drum assemblies each are coupled to a power drive to achieve lifting and lowering of a load supported by elongated elements in a manner well-known in the -art. Each of the four drums 26a support a downwardly extending cable or chain 30, which is directed about respective intermediate pulley
members 32 rotatably mounted on the longitudi
nally disposed upper beams 8, as best shown in
Figures 1 and 2. The lower ends of cables 30 are
adapted to be secured to the grappler system 40 of the invention and lift or lower the containers 4 in a vertical direction as shown by arrow Y in Figure 1.
Referring now to Figures 1 through 7, the grappler system 40 of the invention is best illustrated.
As shown in Figures 1 and 4, grappler system 40 includes two pairs of square tubular beams 42 and 44 which are welded together, one on top of the other, and each pair is adapted to be disposed on a side of the container 4 along the longitudinal dimension thereof. Telescoping inner tubular members 46 and 48 are respectively disposed within beams 42 and 44 in an opposite orientation to each other, such that the longitudinal extent of the grappler system 40 can be modified to adjust to containers having a longer longitudinal dimension. To
achieve such extension, a hydraulic cylinder 50 is
mounted within upper extendible member 48. One
end of hydraulic cylinder 50 is mounted in fixed re
lation to the lower beam 42 by a suitable bracket
52. The extensible end 54 of the cylinder 50 is affixed by a suitable connector to inner member 48.
This coupling permits the inner element 48 to
move telescopically outwardly from within upper
beam 44 to lengthen the longitudinal extend of the
grappler system.
The hydraulic cylinder 50 is coupled to a suitable source of hydraulic pressure (not shown). The extensible movement of upper inner member 48 is coordinated with the lower inner member 46 by a
pulley system, which causes the lower inner mem
ber 46 to extend outward from lower beam 42 at the same rate as the upper beam 48. The pulley
system consists of four fixed pulley elements 56,
57, 58 and 59 suitable affixed to the frame. Pulleys
56, 57, 58 and 59 support cables 60 and 60a which
are affixed to inner member 46 and 48, whereby
upon extension of the hydraulic device 50, both
end portions of inner beams 46 will extend out
wardly in opposited directions to increase the
length of the grappler system. Withdrawal of the
cylinder 50 will likewise reduce the length from its
extended configuration as desired.
As best shown in Figure 4, a pair of brackets 62
are welded to the upper surface of both upper
beams 44 adjacent their ends. Each bracket 62 is
provided with a hole through which a respective
hook connection 64, attached to the end of the four
cables 30, is inserted to suspend the grappler sys
tem 40 from the bridge 20. The extensible end of inner telescopic member 48 is secured to a bracket 70 having an upper horizontally disposed section 72 and an integrally downwardly dependent body 74, having a lower edge situated beneath the lower beam 42. The body 74 of the bracket 70 is formed as a rectangular, tubular structure having a pair of vertical plates 76, an upper plate 78, and open bottom, the structure being welded together as best shown in Figures 1, 2 and 4.The inner portion of plate 78 and a lower angled section 79 form the horizontal surfaces of upper section 72 and are attached to member 48 by bolt assemblies 79'. Similarly, a bracket 80 is secured to the extensible end of the lower inner member 46 and includes an inwardly disposed portion 82 suitable bolted thereto as illustrated in Figures 4 and 5.
A downwardly depending hollow body 84 having an open bottom extends downward to a bottom edge in approximate alignment with the bottom of bracket 70. Side latching mechanisms 90, situated in the lower portions of brackets 70 and 80, extend inwardly to confront both sides of a container 4 positoned therebetween. As shown in Figure 5, a latching assembly 90 includes a cylindrical casing 92 having a known hydraulic cylinder therein, which is coupled to an appropriate source of hydraulic fluid (not shown). The extensible end of the hydraulic cylinder 90 is directed inwardly and carries a pin 94 having a shaped end. Pin 94 is adapted to be inserted into the holes in the bottom corner casting of a container 4 to latch the grappler system 40 to the sidewall of a container at four locations.As illustrated in Figure 1, latching mechanism 90 is inserted to lift the bottom corner casing of a container stacked over a lower one.
As best shown in Figure 1 and 5, brackets 70 and 80 support a pair of identical cross beams 100 respectively adapted to span the two ends of a container 4. The cross beams 100 comprise a plurality of elongaged plates welded together to form a generally U-shaped configuration having an upper horizontal plate 102 and a pair of downwardly disposed walls 104 welded thereto as best shown in
Figure 6. A pair of spaced cross plates 108 are welded at each end of cross beams 100 between walls 104. Four front latching mechanism 110 extend downward in securement between each pair of plates for latching the top corner castings at the front and rear of the container which is beneath the container to which the latching mechanisms 90 are secured.
As best shown in Figures 5, 6 and 7, the latching mechanisms 110 each comprise a square tubular body 112 having an upper portion extending upward between plates 108. The body 112 is secured to the cross beams 100 by an elongated shaft assembly 114 which is disposed in a vertical elongated slot 116 formed in opposed walls of body
112. A suitable hydraulic cylinder assembly 120 extends through the bottom portion of the body 112 and includes a tubular housing a casing 122 extending through the bottom portion of the body
112. The casing is secured thereto by plates 124 suitably affixed to both the body of casing 122 and the housing 112. A hydraulic cylinder 126 having an extensible end 128 is mounted in casing 122 and is in fluid communication with a source of hydraulic fluid (not shown).The extensible end 122 of each cylinder supports a pin 130 which is adapted to be inserted into the holes of the upper front and back corner castings. As can be seen in Figures 6 and 7 the weight of the latching mechanism 110 causes the body 112 to drop to its lowest position because of slot 116. At such a position the respective pins 130 may be oriented with the holes in the top corner castings of both the front and the back of the bottom container 4.In addition, upon withdrawal of the pins 130 from the top corner castings to release a bottom container independently of the container thereabove as will be described, the entire grappler system 40 can be lowered onto a support surface, in absence of the lower independently released container, without damage to the front latching mechanism, since the slot 116 permits the body 112 thereof to withdraw into beams 100 without damage thereto.
Four corner posts 140 are secured to the respective ends of the cross beam members 100 and are formed as a pair of right angle sections that extend upward to a position just above a third container in a stack. The upright posts 140 act as guides to enable the corners of the containers above the grappler to be supported during lifting. At the upper ends of the corner posts 140, a pair of hydraulic cylinders 150 and 152 are operatively positioned.
The cylinders have extensible ends 156 and 158 which can apply a gentle centering force against the upper container in operation (as shown in spaced relation in Figure 8), such that correct orientation of the containers is achieved during lifting.
In operation of the lifting apparatus of the invention, the system may be moved and manipulated over a stack of containers, which can be three or more in each stack. As shown in Figure 3, the bridge 20 may be moved to a position over one of a plurality of stacks over which the gantry crane has been positioned, or where one or a stack is to be moved. The bridge 20 is then operated to lift a stack thereunder or to lower or lift a stack into a position under the bridge. When the bridge is situated over a stack to be lifted, the grappler system 40 is lowered under the action of the power means (not shown) operating the pulley cable system 30.
A known hole sensing device (not shown) may be employed, such that the lowering of the grappler system 40 to the correct position in alignment with a hole may automatically be determined. These devices are capable of sensing the present of each of the holes within the bottom side corner castings and the upper front and back corner castings of the two lower containers to align each of the pin members of respective latching assemblies 90 and 110 with the holes for a latching operation. The latched containers thereby may be lifted upward in a manner that the upper portion of the stack of containers 4 may extend above both the upper beams 8 of the crane and the upper portions of the bridge 20, because of its open center configuration permitting the passage of the containers therethrough.
In addition, the bottom container of the stack may be independently released by unlatching of the front and back latching assemblies 110 without disturbing support of the remaining container secured to the grappler 40 by latching mechanism 90. The lifting apparatus 2 herein described is capable of not only lifting a stack of items in the manner described, but is also capable of lifting one item at a time when appropriate.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, many modifications may be made to adapted a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, it is intended that invention not be limited to the particular embodiment disclosed as the best mode contemplated for carrying out this invention, but that the invention will include all embodiments falling with the scope of the ap
