[0038] In the following description, like reference characters designate like or corresponding parts throughout the figures.

2018202276 29 Mar 2018

DESCRIPTION OF EMBODIMENTS [0039] Referring now to Figure 6, there is shown an apparatus 1 (hereinafter ‘guide apparatus’) for the positioning of an intermodal container 200 and a container handling apparatus 100 (hereinafter ‘handling apparatus’) for engagement of the container 200 by the handling apparatus 100. Together, the guide apparatus 1 and the handling apparatus 100 form part of a container handling system.

[0040] Referring now to Figures 1 through 5, the guide apparatus 1 comprises an elongate base 2 for supporting the container 200, the base 2 comprising a pair of lengthwise extending sides 2a, and a pair of ends 2b, an upstanding side wall 4 for one side of the base 2, an upstanding end wall 6 for each end 2b of the base 2, so that the walls cooperate to form wall comers, and each wall 4 and 6 extends well above any container 200 positioned on the base.

[0041 ] The upstanding side wall 4 is divided into two spaced apart portions, each portion being located at a comer of the base 2.

[0042] Walls 4 and 6 can be straight (90 degrees) from the base 2 to the top, or the walls can start straight (90 degrees) and then at a point higher than top of container angle outward (up to 45 degrees) away from the container location. Moreover, walls 4 and 6 extend considerably higher than a container 200 so that these can capture the swinging handling apparatus 100.

[0043] Back supports 7 absorb excess shock associated with the increased weights of a tippler as compared with a standard container lifting spreader. Central shock absorbing legs are used to soften the impact loads on the levelling pads. These shock absorbing legs can have mbber/wood/spring type dampeners attached during operation.

[0044] The base 2 comprises means for locating the container 200 relative to the base 2 by positively engaging the container 200 with pins or spiggots 3 sized and shaped for insertion into container ‘twistlock’ points or comer fittings of the type found on intermodal containers.

[0045] Optionally, the guide apparatus 1 comprises more than one set of pins 3, for locating more than one size of container 200 relative to the base 2. For instance, the base 2 may comprise pins for locating 20’ and 40’ ISO (shipping) containers.

[0046] Alternatively, the guide apparatus 1 comprises more than one set of pins 3 for locating containers 200 of the same size in different positions, so that, for instance, the container handling

2018202276 29 Mar 2018 apparatus 100 can be guided using one wall comer (between walls 4 and 6 at one end) in preference to the other.

[0047] The apparatus 1 further comprises an outrigger assembly 10 extending outward from a position at or near each comer of the base 2, for stabilising the apparatus 1.

[0048] Each outrigger assembly 10 comprises an outrigger arm 12, a linear actuator 20 (a hydraulic ram in this case) depending from an outer position of the outrigger arm 12, and a ground engaging foot 30 depending from a free end of the linear actuator 20. The feet 30 are connected to the linear actuator 20 via a ball joint, so as to compensate for uneven surfaces, and to improve load distribution.

[0049] This foot 30 is driven by extension of the actuator 20 toward the ground and into ground engagement, and retractable away from the ground by retraction of the linear actuator 20. In this way, the feet 30 can be employed to level the base 2.

[0050] The base 2 of the guide apparatus comprises a power pack 50 (hydraulic pump and motor) for powering all of the linear actuators 20, and a control system for the power pack 50. In one form this control system comprises means for sensing (such as a mercury tilt switch) whether the base 2 is level both longitudinally and transversely, and means for actuating the linear actuators (control valves, solenoids etc.) as required to level the base 2.

[0051] Without these levelling characteristics, the containers 200 are not level and the handling apparatus 100 can have difficulty interfacing with the container 200.

[0052] Referring now to Figure 6 and 8, it can be seen that the handling apparatus 100 comprises externally directed impact absorbing means for absorbing impacts resulting from collisions with the guide apparatus 1 at least. More particularly, the handling apparatus 100 is fitted with a plurality of heavy duty bumper elements 110 of, for example, an elastomeric material such as rubber. These bumper elements 110 are secured to external surfaces of the handling apparatus 100, including at or near or along edges or comers of external surfaces which are likely to be involved in impacts during normal use of the handling apparatus 100.

[0053] Preferably, these bumpers 110 are secured to the handling apparatus 100 by releasable means such as fasteners or clips, so that the bumper elements 110 can be replaced as required.

2018202276 29 Mar 2018 [0054] The base 2 of the guide apparatus 1 also comprises slots for receiving tines of a forklift, and lifting lugs or handling via a reach stacker; in this way the guide apparatus can be moved and positioned as required.

[0055] In use, a full container 200 is positioned on the pins of the base 2 using a lifting device such as a forklift, reach stacker, crane etc. The handling apparatus 100, which is suspended from a crane, is then carefully positioned between the walls 4 and 6, and guided into a wall comer formed between an end wall and a side wall of apparatus 1, so that bumpers 110 fitted at or near this comer of the handling apparatus 100 bear against this wall comer. The handling apparatus 100 is then lowered, potentially bumping and dragging against the walls as it is lowered, until it comes to rest against the top of the container 200 in a position which is ideal for connection of the handling apparatus 100 with the container 200.

[0056] Pivotal to the success of the above described operation is the positioning of the walls 4 and 6 relative to the container position on the base 2, and particularly the spacing of the walls 4 and 6 from the base 2, as this will determine whether the handling apparatus 100 is correctly positioned for engagement with the container 200. The spacing of the walls 4 and 6 from the base 2 will be selected to substantially match the extent of handling apparatus 100 (tippler) overhang relative to the container 200, and should take into account the additional overhang created by the bumpers 110.

[0057] The container 200 can then be lifted up and swung away from the guide apparatus 1 for emptying.

[0058] In cases where the handling apparatus 100 is a tippler, the container 200 is emptied by way of being upended into a hold of a ship.

[0059] The system and apparatus according to the present invention has been found to yield the following benefits or advantages:

a. Quicker placement of tippler onto containers and improved efficiency of tippler operation;

b. Significant reduction in tippler twist lock malfunctions;

c. Reduction in damage to tippler.

d. Reduction in damage to containers.

2018202276 29 Mar 2018

e. Safer operation, as it eliminates the need for personnel on the ground guiding the tippler onto the container.
