DETAILED DESCRIPTION

(8) Referring to FIGS. 1-5, shown therein are various depictions of a transport container 100 constructed accordance with an exemplary embodiment of the present invention. The transport container 100 is designed to carry various components of an air-cooled heat exchanger, which may include a fan hub 200, fan vanes 202 and assorted parts 204. As is well understood in the art, the fan vanes 202 are configured for attachment to the fan hub 200, which is connected to a drive shaft for rotation by a motor or engine. The fan hub 200 and fan vanes 200 may be constructed from lightweight metal or composite materials.

(9) The transport container 100 generally includes a body 102 and a lid 104. The body 102 has a front 106, back 108, right side 110, left side 112 and floor 114. The lid 104 is sized and configured to rest securely on the top surfaces of the body 102. Unless otherwise indicated, the various parts of the transport container 100 can be constructed from a durable plastic that is resistant to moisture. Suitable materials of construction include high density polyethylene and reinforced acrylonitrile butadiene styrene (ABS) plastics that can be molded, extruded or otherwise formed into the component parts of the transport container 100.

(10) The body 102 includes a plurality of feet 116 that are configured to support the body 102 on a surface or on another transport container 100. The body 102 also includes a plurality of tabs 118 that extend above the upper surface of the front 106, back 108, right side 110 and left side 112. The tabs 118 are configured to be received within corresponding lower recesses 120 on the underside of the lid 104. The engagement between the tabs 118 and the lower recesses 120 help align and secure the lid 104 to the body 102. The lid 104 optionally includes a plurality of upper recesses 122 on the top of the lid 104 that are sized and positioned to receive the feet 116 of a transport container 100 when two transport containers 100 are vertically stacked.

(11) The feet 116 and floor 114 are configured to define fork channels 124 within the body 102. The fork channels 124 are sized and configured to facilitate lifting the transport container 100 with a standard forklift. As noted in FIG. 1, the transport container 100 includes fork channels 124 that are accessible from the front 106, back 108, right side 110 and left side 112. The lid 104 can include strap channels 126 that extend internally through the lid 104. The strap channels 126 permit the use of straps (not shown) for securing the lid 104 to the body 102. The straps can be routed through the strap channels 126, around the body 102 and through the fork channels 124.

(12) In the embodiment depicted in FIG. 1, the body 102 further includes a central divider 128 that extends between the front 106 and back 108. The central divider creates two internal compartments 130 that are sized to contain the fan vanes 200 (as illustrated in FIGS. 2-4). The central divider 128 includes a vertically oriented hub post 132 that has an outer diameter that is substantially the same as the outer diameter of the fan drive shaft so that the hub post 132 can be inserted into the fan hub 200. In this way, the fan hub 200 can be placed onto the hub post 132 to support the fan hub 200 within the transport container 100. Although not depicted in FIGS. 2-4, it will be appreciated that additional internal packing can be used to bolster and support the fan hub 200, fan vanes 202 and other parts 204 within the transport container 100.

(13) Turning to FIG. 5, shown therein is a perspective view of the transport container 100 with an optional parts container 134. The parts container 134 is sized to hold various accessories and parts used to assembly the air-cooled heat exchanger. In exemplary embodiments, the parts container 134 includes a plurality of abutments 136 that are sized and configured to be received within the upper recesses 122 of the lid 104. In this way, the parts container 134 can be securely positioned on top of the lid 104.

(14) Turning to FIGS. 6 and 7, shown therein are various depictions of multiple transport containers 100 stacked for storage or shipment. In FIG. 6, three transport containers 100 are vertically stacked. The substantially rigid transport containers 100 are designed to support the weight of multiple fully-loaded transport containers 100. FIG. 7 depicts an exemplary manner in which twenty-seven (27) transport containers 100 have been stacked and loaded into a large commercial trailer for shipment. Although the transport container 100 has been described and illustrated in connection with transport services, it will be appreciated that the transport container 100 can also be used for storing components associated with air-cooled heat exchangers.

(15) The transport container 100 presents a substantial improvement over conventional methods of storing and transporting parts for an air-cooled heat exchanger. The transport container 100 is reusable, durable, weather resistant and suitable for long-term storage of fan components. It is to be understood that even though numerous characteristics and advantages of various embodiments of the present invention have been set forth in the foregoing description, together with details of the structure and functions of various embodiments of the invention, this disclosure is illustrative only, and changes may be made in detail, especially in matters of structure and arrangement of parts within the principles of the present invention to the full extent indicated by the broad general meaning of the terms expressed herein. It will be appreciated by those skilled in the art that the teachings of the present invention can be applied to other systems without departing from the scope and spirit of the present invention.
