Description
SHIP LOADING SYSTEM
The present invention relates to a ship loading system that utilizes a retractable roof for covering an upper surface of the boom, the cargo discharge chute, and the cargo hatch through which material is being loaded into the ship's cargo holds, or more particularly, to a ship loading system having a retractable roof for covering an upper surface of the boom, the cargo discharge chute, and the hatch through which material is being loaded into the ship's cargo holds to provide a ship loading system having all-weather loading capability.
BACKGROUND OF THE INVENTION
It is common that ocean-going ships that are used to transport unpackaged or bulk particulate or fluent cargo, such as alfalfa pellets, agricultural products, minerals, salts, potash and other fertilizers, and other types of goods, are generally constructed with at least one large hatch or opening in the deck of the ship that generally permits access to the hold below where such materials are stored. In normal loading operations, during good weather, a conveyorized boom, having a cargo discharge chute, is lowered into the opening and the cargo is dispensed. Such a boom is usually moved slightly during the loading operation to insure that the particulate or fluent material is spread uniformly within the hold of the ship. However, many bulk products, such as agricultural grains and processed materials, such as potash and salt, can be severely damaged if they are exposed to rain or other sources of water and, therefore, loading these types of products onto ships must often be delayed until the weather conditions improve. This is not only a major inconvenience, but it is also very uneconomical (as inclement weather can substantially delay or inhibit the loading of the cargo onto the barge or ship resulting in increased costs) and it can be prohibitive to require a ship to wait for improved weather before loading can proceed.
It would therefore be advantageous to have an improved ship loading system that utilizes a retractable roof for covering an upper surface of the boom, the cargo discharge chute, as well as the hatch opening through which the material will pass while being placed into the ship's cargo hold.
It would be further advantageous to have a ship loading system having a retractable roof for covering an upper surface of the boom and the cargo discharge chute to provide a ship loading system having all-weather loading capability. To this end, the present invention effectively addresses this need.
SUMMARY OF THE INVENTION
The present invention provides an improved ship loading system that utilizes a retractable roof for covering an upper surface of the boom, the cargo discharge chute, as well as the hatch opening through which the material will pass while being placed into the ship's cargo hold, and which has all-weather loading capability.
According to one aspect of an embodiment of the present invention, there is provided a ship loading system for a vessel, comprising a selectively movable boom section constructed and arranged for attachment to a frame section; a cargo discharge chute constructed and arranged for engagement with the boom section, the cargo discharge chute being constructed and arranged for discharging materials received from the boom section into a hold or hatch of the vessel; and a selectively retractable cover extending over the boom section, the hold or hatch of the vessel and the cargo discharge chute.
According to another aspect of an embodiment of the present invention, there is provided a ship loading system for a vessel, comprising a selectively movable boom section constructed and arranged for attachment to a frame section, and having a conveyor belt for carrying material to be loaded into a hold or hatch of the vessel; a cargo discharge chute constructed and arranged for engagement with the boom section, the cargo discharge chute being constructed and arranged for discharging materials received from the boom section into the hold or hatch of the vessel;
positioning means connected to the boom section which are constructed and arranged to position the boom

DETAILED DESCRIPTION OF THE INVENTION
The invention will be described for the purposes of illustration only in connection with certain embodiments; however, it is to be understood that other objects and advantages of the present invention will be made apparent by the following description of the drawings according to the present invention. While a preferred embodiment is disclosed, this is not intended to be limiting. Rather, the general principles set forth herein are considered to be merely illustrative of the scope of the present invention and it is to be further understood that numerous changes may be made without straying from the scope of the present invention.
Referring to Figures 1A and 1B, a first exemplary embodiment of the ship loading system 1 of the present invention is shown. In an exemplary embodiment, the ship loading system 1 relates to a ship loading system having all-weather loading capability, wherein grains, other particulate materials or materials can be loaded in all types of weather conditions without risk of damage to the grains or materials. In particular, a main boom 3 is provided which is constructed and arranged for attachment to a frame section 5. The main boom 3 can be positioned, by means of hoisting cables 7 and hoisting winches 9 (such as a winch luffing system), over the hatch or hold 11 of a vessel or ship to be loaded, and a levelling boom 13 in association and connection with the main boom 3 interacts such that the levelling boom 13 sets the elevation of the main boom pivot for ship loading activities. This allows for the adjustment and positioning of the main boom 3 depending on the height of the vessel to be loaded. Such movement of the main boom 3 and the levelling boom 13 can occur by power supplied electrically, mechanically, hydraulically or through use of a pneumatic system, though other means could also be utilized, as would be appreciated by one skilled in the art.

Figure 3 illustrates the main boom 3 being raised to an upper operating position, and Figure 4
4 illustrates the main boom 3 being lowered to a lower operating position.
Figure 5 illustrates the main boom 3 being raised, once loading activities have concluded, to a non-operating "parked" position.
A cargo discharge chute 15 is provided on the main boom 3, to allow for the transfer of the grains, other particulate materials or materials into the hatch or hold 11 of a vessel or ship to be loaded. It will be understood that the positioning of the cargo discharge chute 15 along the main boom 3 can be selectively varied, but generally will be at an end thereof. Of course, a conveyor belt (not shown) is in association with each of the main boom 3 and levelling boom 13, and runs along upper surfaces thereof to deliver the materials ultimately through the cargo discharge chute 15 and into the hatch or hold 11.
With reference to Figures 2A and 2B, a retractable roof 17 is provided, which can be coupled to the main boom 3 and extended to cover the hatch or hold opening on the vessel, and, when expanded, extends over the main boom 3, the hold or hatch 11 of the vessel and the cargo discharge chute 15. The hold or hatch 11 of the vessel would then be opened, once safely under the retractable roof 17, and the cargo discharge chute 15 aligned so as to initiate loading activities. The retractable roof 17 can also be partially extended, or extended more to one side than another, when clearance issues dictate.
Figure 2A illustrates the retractable roof 17 in a retracted position, and assuming a position alongside sides of the main boom 3. Figure 2B illustrates the retractable roof 17 hingedly expanded and covering the upper surfaces of the main boom 3, the opening for the hold or hatch 11 of the vessel and the cargo discharge chute 15.
In operation, materials from a feed conveyor 19 are loaded by means of a travelling tripper 21 onto the conveyor belt (not shown) for travel along each of the levelling boom 13 and main boom 3, to deliver the materials ultimately through the cargo discharge chute 15 and into the hatch or hold 11.
In a further exemplary embodiment, a radio remote control unit (not shown) can be utilized to allow the operator to control all necessary shiploading functions in all
