[0002] The present disclosure relates to the transfer and movement of international shipping containers in port and transfer terminal facilities. In particular, the present disclosure relates to an overhead transport system and route management system for transporting shipping containers from one location in a port, terminal or warehouse facility to other location(s).Background of the Invention

[0003] Graham US 3,091,188 A discloses a system for transferring cargo in large containers. The system comprises a trestle network having a plurality of portions, each of the portions comprising a plurality of separate lanes. A first transfer-way interconnects one end of all the lanes of both portions, and a second transfer-way interconnects the other ends of all the lanes to form a plurality of complete and interconnected loops on the trestle network. One of the portions of the network is disposed above one terminal area and another of the portions of the network is disposed above another terminal area. A transfer vehicle travels on the trestle network, and is adapted to receive and deliver containers from and to one of the terminal areas below the trestle network when the transfer vehicle is in one of the lanes.

[0004] Brickner US 4,973,219 A discloses a grid rail container handling and storage system. The system includes (a) a high density container storage yard having an overhead grid rail system providing access to storage locations in the yard, (b) a loading and unloading buffer for the container storage yard, (c) a crane for loading and unloading containers from or to the buffer, and (d) a plurality of shuttle vehicles for movement on the overhead grid rail system to different locations in the container storage yard. Each shuttle vehicle has an active track switching mechanism for selectively switching through passive overhead rail switches.

[0005] Benedict et al. US 2008 / 0213073 A1 discloses a system for storing and transporting shipping containers with an overhead grid guide track structure. At least one transfer unit is moveably mounted to the grid guide track structure and includes a selectively operable drive mechanism for moving the at least one transfer unit along the tracks of the grid guide track structure. A container engaging mechanism is suspended from a hoist mechanism carried by the at least one transfer unit for raising and lowering the container engaging mechanism. The container engaging mechanism cooperatively engages a shipping container so that an engaged shipping container can be conveyed to a selected location beneath the overhead grid guide track structure.

[0006] Tabler US 2009 / 0078535 A1 discloses a slip tube system for transporting a load along a conveying path of an overhead conveyor system. A stationary frame has at least one rotating shaft with a shaft axis extending along the conveying path of the stationary frame, and a movable carriage configured to transport a load along the conveying path. A slip tube is placed on one or more of the rotating drive shafts. As the drive shaft rotates, traction is developed between the rotating shaft and an inner surface of the slip tube, and between an outer surface of the rotating slip tube and the driven wheels attached to the carriage to provide sufficient drive force to propel the carriage and the load along the conveying path.

[0007] Approximately 90% of non-bulk cargo worldwide is transported via intermodal containers arranged on ships. When these containers arrive at ports (either by land or by sea) they are moved onto or from ships, trains, and trucks.

[0008] Transferring containers from one mode of transportation to another is time and energy intensive. Loading / unloading ships is often conducted at the ground level with various mechanical machines such as cranes, trucks, forklifts, and straddle carriers. Often these machines burn fossil fuels and are inefficiently applied.

[0009] One particular problem with current methods for transferring intermodal shipping containers is that they require a large amount of ground space for maneuvering the containers into place. Containers can be up to 53 feet (16.15 meters) long, and can weigh in the range of 35-40 tons (31.8-6.3 metric tons). Ground space is a premium at and around busy ports. Another problem with current methods for transferring containers is that the large amount of time taken to unload ships often leads to port congestion and container backlog.

[0010] To alleviate many of these problems, the use of overhead rail transportation systems has been suggested. An overhead monorail solution provides advantages that would significantly improve container port operations, however it is not without its challenges. One challenge in particular involves quickly loading / unloading intermodal containers of various sizes onto the overhead rail transportation system.

[0011] What is needed is a carrier system designed for efficient material handling and transferring of intermodal containers from one form of transportation to another, and transporting containers from one area to another (for example, port area to inland terminals). The carrier works via an overhead rail transportation system to help eliminate, or at least reduce, backlogs at ports and clear up port congestion.

[0012] In some embodiments, the carrier would not directly utilize fossil fuel and as a result would reduce port pollution often caused by traditional methods.Summary of the Invention

Detailed Description of Preferred Embodiment(s)

[0028] The following is a detailed description of a fixed motorized container carrier (FMCC), a motorized adjustable container carrier (MACC), and a motorized trolley container carrier (MTCC).Fixed Motorized Container Carrier (FMCC)

[0029] FIG. 1 is an isometric view of fixed motorized container carrier 100. Fixed motorized container carrier (FMCC) 100 includes, among other things, motorized trolley assemblies 110, body 130, container engagement devices 160 mounted on end beams, first bumper 140 and second bumper 145. In some embodiments, container engagement devices 160 are twist locks.

[0030] Motorized trolley assemblies can include, among other things, wheel clean-sweep plate(s) 111, motor(s) 112, support frames with cross beam connector(s) 113, gearbox(es) 114, load wheel assemblies 120, king pin(s) 116, top guide wheel(s) 117, bottom guide wheel(s) 118 and anti-tilt guide wheel(s) 119.

[0031] Motorized trolley assemblies 110 can be self-propelled. Motorized trolley assemblies 110 are configured to move FMCC 100 along rail 205 on overhead track 210 (see FIG. 5). In some embodiments, track 210 is a monorail. In some embodiments, motorized trolley assemblies 110 can operate in multiple directions. In some embodiments (such as the one shown in FIG. 5) track 210 is flanged.

[0032] In some embodiments, track 210 is an "inverted-u" enclosed type track. In at least some of these embodiments, wheels 115 are at least partially enclosed in track 210. In some embodiments, track 210 is a patented type track. In other embodiments, track 210 is a single rail track in which body 130 is suspended from motorized trolley assemblies 110 with a "c-frame structure" (not shown) that wraps around track 210 and connects to at least one motorized trolley assembly 110 located on the upper side of track 210. Track 210 can be made up of, but is not limited to, steel beams and / or reinforced concrete beams.

[0033] In one embodiment, FMCC 100 has one motorized trolley assembly 110. In some embodiments, FMCC 100 can have a plurality of motorized trolley assemblies 110. In the embodiment shown in FIGS. 1-5, FMCC 100 has two motorized trolley assemblies 110 each with four load wheel assemblies 120. In some embodiments, each of motorized trolley assemblies 110 has one, two, three, four, five, six, seven, or eight load wheel assemblies 120. In yet another embodiment, FMCC 100 has three motorized trolley assemblies 110. In some embodiments, motorized trolley assemblies 110 of FMCC 100 are redundant in nature, meaning that if one or more motorized trolley assemblies 110 fail, FMCC 100 can still function.

[0034] Load wheel assemblies 120 can be configured to operate with attached gearbox(es) 114 and motor(s) 112 (driven wheels). In other or the same embodiments, load wheel assemblies 120 can be configured to operate without gearbox(es) 114 and motor(s) 112 (free wheels).

[0035] FIG. 1 shows FMCC 100 with two four-wheel trolley assemblies 110, each with two free wheels and two driven wheels. In other embodiments, trolley assemblies 110 can have two wheels. The driven wheel design is redundant in nature, meaning that if one or more of motors 112 or gearboxes 114 fail, FMCC 100 can still travel along track 210, as long as one gearbox-motor set remains functional.

[0036] In some embodiments, motorized trolley assemblies 110 are activated based on the power requirements of FMCC 100. For example, at times FMCC 100 can use less power, such as when it is not carrying a container, it is possible to activate only a single assembly. In instances when more power is useful, such as when FMCC 100 is carrying a heavy container, multiple assemblies 110 can be activated. This configuration saves both energy and wear on motorized trolley assemblies 110.

[0037] In some embodiments, motor(s) 112 and / or gearbox(es)114 of motorized trolley assemblies 110 are synchronized, meaning they maintain appropriate synchronized speed (wheel rpm) for straights and turns. In some embodiments, this is done via variable frequency drive control systems.

[0038] The horsepower and / or motor count of motorized trolley assemblies 110 can be configured based on the specific demands of the environment in which FMCC 100 is to be deployed. In some embodiments, such as the ones shown in FIGS. 1-5, two motors 112 are used on each motorized trolley assembly 110.

[0039] Motorized trolley assemblies 110 can drive load wheel assemblies 120 and corresponding connection-flange points for various-sized motors 112. Motor(s) 112 can be selected to induce various accelerations and / or maintain velocities. In some embodiments, FMCC 100 can reach speeds exceeding 24 kilometers per hour and move containers weighing up to 71,600 lbs. (32,477 kg). In some embodiments, FMCC 100 can reach speeds exceeding 75 kilometers per hour and move containers weighing up to 136,000 lbs. (61,688 kg). Motor(s) 112 can be configured based on the specific demands of the environment in which FMCC 100 is to be deployed.

[0040] In some embodiments, motor(s) 112 is / are electric motors such as AC and / or DC electric motors. In other or the same embodiments, motor(s) 112 can be, among other things, heat engines (including combustion engines) and / or physically powered motors. In some embodiments, multiple types of motors 112 are present on a single FMCC 100.

[0041] When motors 112 are electric, FMCC 100 has the added benefit of reducing pollution caused by the burning of fossil fuels.

[0042] In some embodiments, motor(s) 112 can include internal braking mechanisms (not shown) and / or an energy recapture system that recover energy from braking. In other or the same embodiments, external brakes can be utilized. In some embodiments, the external brakes are discs and / or can brake multiple wheels at once.

[0043] In some embodiments, motor(s) 112 are mounted vertically to create a narrow profile. In certain embodiments, the power transfer from motor shaft to load wheel 115 is conducted through gearbox 114. In some embodiments, gearbox 114 is a helical bevel gearbox. In other embodiments, gearbox 114 can comprise, among other types, spur gear(s), spiral gear(s), or straight bevel gear(s). In certain embodiments, gearbox 114 can drive multiple wheel assemblies 115 at once. In other or the same embodiments, gearbox 114 can include a differential.

[0044] In some embodiments, gearbox 114 transfers the power through a 90-degree change in direction. In certain embodiments, gearbox 114 can have several gearing ratios to increase the efficiency of motorized trolley assemblies 110. In some embodiments, gearboxes 114 and / or motors 112 are configured to bolt-on to motorized trolley assemblies 110 for ease of replacement.

[0045] Various parts of the FMCC 100, including the side plates and cross beam connector 113 of motorized trolley assemblies 110 and body 130 can be constructed from various materials including steel plating. Exposed steel can be coated to slow or prevent corrosion and / or rusting. Various parts of the FMCC 100, including the side plates and cross beams 113 of motorized trolley assemblies 110 and body 130 can be constructed from various standard structural shapes.

[0046] Load wheel assemblies 120 can include a shaft and bearing design. In some embodiments, the shaft and bearings are made of high-grade premium alloys. In some embodiments, load wheels 115 can be attached to a high-grade premium alloy normalized steel shaft which is press fitted into a cylindrical roller bearing assembly. Load wheels 115 can be secured to the shaft via a carbon steel end cap fastened with tapered head machine screws.

[0047] In certain embodiments, the cylindrical roller bearing assembly includes high speed roller bearings at each end fitted into a bearing support tube. The support tube can have carbon steel walls with end covers that are fastened at both ends via machine screws.

[0048] The friction surface of load wheel 115 can be made of a variety of materials depending on the properties desired. For example, for high demand applications load wheel 115 can be made of, among other things, flame hardened forged carbon steel. In situations where noise reduction is desired, load wheels 115 can be a special steel alloy and / or have partial and / or complete coatings of natural and / or synthetic rubber(s) / polymer(s). In some embodiments, partial coatings can resemble tires. Load wheels can be coated with polyurethane. In some embodiments, load wheels 115 are pneumatic tires.

[0049] In some embodiments, FMCC 100 can utilize direct positive mechanical engagement or external assist for inclines and declines, via cables / ropes, gears, or chains drives when above 1% grade. In some embodiments, FMCC 100 can climb grades over 15%.

[0050] In some embodiments, load wheel 115 has an outside diameter of essentially 400 mm, although other sizes can be used as well.

[0051] In certain embodiments, load wheels 115 are configured to be easily removed from motorized trolley assembly 110 for maintenance and / or replacement. In some embodiments, this is accomplished via a bolt-on retaining flange.

[0052] In some embodiments, motorized trolley assemblies 110 have various guide wheels configured to keep load wheels 115 in an optimum, or at least improved, alignment with track 210. Guide wheels can be coated with, among other things, rubber and / or polyurethane. In some embodiments, guide wheels can be pneumatic tires. In the embodiment shown, top guide wheels 117 and bottom guide wheels 118 keep FMCC 100 aligned to track 210. Anti-tilt wheels 119 keep motorized trolley assembly 110, and therefore FMCC 100 as a whole, from tilting horizontally when load-shifting occurs.

[0053] In some embodiments, wheel clean-sweep plates 111 are mounted on either or both sides of some, if not all, load wheel assemblies 120 and provide for continuous removal of obstructions or debris that can accumulate on rail 205. In some embodiments, wheel clean-sweep plate 111 as a whole, or just the portion that moves over rail 205, can be made of a replaceable and serviceable high-density, synthetic material to remove obstructions. In some embodiments, wheel clean-sweep plate 111 is made of a steel plate. In some embodiments, wheel clean-sweep plate 111 can incorporate non-adhesive properties that allow for improved discharge of debris collected on a face of wheel clean-sweep plate 111.

[0054] In some embodiments, motor(s) 112, particularly electric motors 112, can receive power-feed from power supply buss(es) installed along the main track. In certain embodiments, these power buss(es) can have corresponding and aligned power pick-up shoes on each motorized trolley assembly 110 for power transfer into the motors and / or for feeding regenerated power back into the system during deceleration, braking and track decline sections.

[0055] Body 130 is connected to motorized trolley assemblies 110. In some embodiments, body 130 is connected to motorized trolley assemblies 110 via king pin(s) 116 (see FIG. 2) and bracket 113. This configuration allows for easy replacement of motorized trolley assemblies 110.

[0056] Kingpin(s) 116 can include a ball swivel top flange, designed with a thrust bearing, configured for descending through from the top, and out the bottom, of bracket 113. Kingpins 116 can rotate within the allotted passageway and can have the ability to absorb vertical and lateral forces. In some embodiments, the lower end of kingpins 116 can have full-circle, eyelet-designed bracket through which a secondary pin is placed, thus joining it with the top of body 130. This configuration allows the system to be readily hooked and unhooked for service and maintenance.

[0057] In other embodiments, body 130 is directly connected to motorized trolley assemblies 110. This direct connection can be accomplished by, among other things, a steel universal joint, a steel eyelet-to-eyelet, or a steel hook-to-eyelet connection.

[0058] First bumper 140 and second bumper 145 are attached to body 130. In some embodiments, first bumper 140 and second bumper 145 are symmetrically designed since FMCC 100 can operate bi-directionally. Bumper assemblies can be made of, among other things, spiral spring-loaded tubes with rubber externals or a similar shock absorbing material such as, but not limited, to leaf-springs or gas shock absorbers. In certain embodiments, first bumper 140 and second bumper 145 are configured so that containers being carried by separate FMCCs 100 cannot, or are at least less likely to, hit each other. First bumper 140 and second bumper 145 also help reduce, if not eliminate, damage caused by collisions between multiple FMCCs 100 and / or external objects.

[0059] The spacing created by first bumper 140 and second bumper 145, can also aid in maintaining safety-rated weight distribution on over-head track 210 and support structure when FMCC 100 are in an accumulated state.

[0060] In certain embodiments, bumpers 140 / 145 are attached to body 130 by a telescoping mechanism so their length from the center of body 130 can be adjusted depending on the length of container 220.

[0061] Body 130 can have various extruding end beams 150 with container engagement devices 160 configured to interact with container 220. In some, if not most embodiments, end beams 150 are fixed relative to each other and are not readily moved.

[0062] In some embodiments, FMCC 100 has multiple end beams 150 that are positioned in such a way that container engagement devices 160 on FMCC 100 can interact with various sized containers 220 without having to have end beams 150 repositioned. For example, in the embodiment shown in FIG. 2, the four exterior end beams 150 are configured to interact with container 220 of a first length (for example 40 feet). The same FMCC of FIG. 2 could also interact with a second container (not shown) with a second length (for example 20 feet), via the four interior end beams 150. In some embodiments, a container of a third length (for example 30 feet) can interact with two interior beams 150 and two exterior beams 150.

[0063] This use of multiple fixed end beams 150 and their corresponding container engagement devices 160 allows a single FMCC 100 to be used with containers 220 of various lengths, without having to adjust its features, either manually or electronically. Often the length of container 220 is one of a few standard sizes.

[0064] These versatile FMCCs 100 lead to less down time in which the spacing of container engagement devices 160 would have to be reconfigured, and / or fewer movable parts which are more likely to break than fixed beams.

[0065] Although FIG. 2 only shows four end beams 150, FMCCs 100 can have various numbers of end beams and as a result, a single FMCC 100 can be configured to work with a large number of containers. In some embodiments, such as the embodiment shown, end beams 150 have container engagement devices 160 located on each end. In other embodiments, end beams 150 terminate at body 130 and have only one container engagement device 160 per each end beam 150.

[0066] In some embodiments, container engagement devices 160 are twist locks that connect directly to shipping containers 220 using the industry standardized four-corner pin locking system. In some embodiments, container engagement devices 160 are rotated electronically with dedicated electric motors. In some embodiments, a pair of container engagement devices 160 are turned with a linkage assembly powered by a single motor. In some embodiments, container engagement device 160 rotation can be driven by electric-driven linear actuators.

[0067] In certain embodiments, various armatures are attached to body 130, such that the same FMCC 100 can be used with containers of various sizes. In some embodiments, the armatures are configured to coordinate with shipping containers 220 of various lengths including, but not limited to 20 feet (6.1 meters), 30 feet (9.1 meters), 40 feet (12.2 meters), 45 feet (13.7 meters), 48 feet (14.6 meters) and / or 53 feet (16.15 meters).

[0068] In some embodiments, a single FMCC 100 is configured to work with multiple sized shipping containers 220.

[0069] In some embodiments, FMCC 100 is configured to work under various external forces including, but not limited to, temperatures ranging from -30 degrees Celsius to 60 degrees Celsius, wind gusts up to 200 kilometers per hour, rain, sleet, hail, and / or snow.

[0070] FIG. 5 is an isometric view of fixed motorized container carrier 100 on track 210 with shipping container 220. Fixed motorized container carrier 100 also includes electronic controls 230. Electronic controls 230 can be powered through a shoe and buss system, such as the one discussed earlier. In some embodiments, electronic controls 230 include controls and power units. In some embodiments, the controls monitor and manage information from the sensor(s) located on the FMCC 100.

[0071] In some embodiments, shipping container 220 is a shipping container. In some embodiments, the length of shipping container 220 is a standard size such as, but not limited to, 20 feet (6.1 meters), 30 feet (9.1 meters), 40 feet (12.2 meters), 45 feet (13.7 meters), 48 feet (14.6 meters) or 53 feet (16.15 meters).

[0072] In some embodiments, track 210 is a monorail, separate from the support structure (steel or otherwise). In other or the same embodiments, track 210 is integrated with the structure (steel or otherwise).

[0073] Although this device has been described as being used with intermodal shipping containers, it can also be employed in other settings such as transporting passenger cars from ferries.Motorized Adjustable Container Carrier (MACC)

[0074] Motorized Adjustable Container Carrier (MACC) 300 is shown in FIG. 13. MACC 300 is designed to provide automatic, hands free adjustment of its own effective frame size to suit the pickup of variously sized shipping containers.

[0075] FIG. 13 is an isometric view of MACC 300. Motorized adjustable container carrier (MACC) 300 includes motorized trolley assemblies 310, body 330, and bumpers 340. Motorized adjustable container carrier (MACC) 300 can include, among other things, container engagement devices 360 (which are twist locks in some embodiments) mounted on end beams 350

[0076] Motorized trolley assemblies 310 include motor(s) 312, gearboxes 314. Motorized trolley assemblies 310 can include, among other things, wheel clean-sweep plate(s) 311, load wheel assemblies 320, king pin(s) 316, top guide wheel(s) 317, bottom guide wheel(s) 318 and anti-tilt guide wheel(s) 319.

[0077] Motorized trolley assemblies 310 are self-propelled. Motorized trolley assemblies 310 are configured to move MACC 300 along rail on overhead track 210 (see FIG. 20). In some embodiments, track 210 is a monorail. In some embodiments, motorized trolley assemblies 310 can operate in both directions. In some embodiments, track 210 is flanged.

[0078] In some embodiments, track 210 is an "inverted-u" enclosed type track. In at least some of these embodiments, wheels 315 are at least partially enclosed in track 210.In some embodiments, track 210 is a patented type track.

[0079] In other embodiments, track 210 is a single rail track in which body 330 is suspended from motorized trolley assemblies 310 with a "c-frame structure" (not shown) that wraps around track 210 and connects to at least one motorized trolley assembly 310 located on the upper side of track 210. Track 210 can be made up of, but is not limited to, steel beams and / or reinforced concrete beams.

[0080] In one embodiment, MACC 300 has one motorized trolley assembly 310. In some embodiments, MACC 300 can have a plurality of motorized trolley assemblies 310. In the embodiments shown in FIGS. 13-20, MACC 300 has two motorized trolley assemblies 310 each with four load wheel assemblies 320. In some embodiments, each motorized trolley assembly 310 has two load wheel assemblies 320. In yet another embodiment, MACC 300 has three motorized trolley assemblies 310. In some embodiments, motorized trolley assemblies 310 of MACC 300 are redundant in nature, meaning that if one or more motorized trolley assemblies 310 fail, MACC 300 can still function.

[0081] Load wheel assemblies 320 can be configured to operate with attached gearbox(es) 314 and motor(s) 312 (driven wheels).

[0082] FIG. 13 shows MACC 300 with two four-wheel trolley assemblies 310, each with two free wheels and two driven wheels. In other embodiments, trolley assemblies 310 can have two wheels. In some embodiments, the driven wheel design is redundant in nature, meaning that if one or more of motors 312 or gearboxes 314 fail, MACC 300 can still travel along track 210, as long as one gearbox-motor set remains functional.

[0083] In some embodiments, motorized trolley assemblies 310 are activated based on the power requirements of MACC 300. For example, when little power is needed, such as when MACC 300 is not carrying a container, only one assembly 310 may be activated. In instances when more power is required, such as when MACC 300 is carrying a heavy container, multiple assemblies 310 can be activated. This configuration saves both energy and wear on motorized trolley assemblies 310.

[0084] In some embodiments, motor(s) 312 and / or gearbox(es) 314 of motorized trolley assemblies 310 are synchronized, meaning they maintain appropriate synchronized speed (wheel rpm) for straights and turns. In some embodiments, this is done via variable frequency drive control systems.

[0085] The horsepower and / or motor count of motorized trolley assemblies 310 can be configured based on the specific needs of the environment MACC 300 is to be deployed. In some embodiments, such as the ones shown in FIGS. 13-20, two motors 312 are used on each motorized trolley assembly 310.

[0095] The friction surface of load wheel 315 can be made of a variety of materials depending on the properties desired. For example, for high demand applications the load wheel 315 can be made of, among other things, flame hardened forged carbon steel. In situations where noise should be minimized, or at least reduced, load wheels 315 can be a special steel alloy and / or have partial and / or complete coatings of natural and / or synthetic rubber(s) / polymer(s). In some embodiments, partial coatings can resemble tires. Load wheels can be coated with polyurethane. In some embodiments, load wheels 315 are pneumatic tires.

[0096] In some embodiments, MACC 300 can utilize direct positive mechanical engagement or external assist for inclines and declines, via cables / ropes, gears, or chains drives when above 1% grade. In some embodiments, MACC 300 can climb grades over 15%.

[0097] In some embodiments, load wheel 315 has an outside diameter of essentially 400 mm, although other sizes can be used as well.

[0098] In certain embodiments, load wheels 315 are configured to be easily removed from motorized trolley assembly 310 for maintenance and / or replacement. In some embodiments, this is accomplished via a bolt-on retaining flange.

[0099] In some embodiments, motorized trolley assemblies 310 has various guide wheels configured to keep load wheels 315 in an optimum, or at least improved, alignment with track 210.

In the embodiment shown, top guide wheels 317 and bottom guide wheels 318 keep MACC 300 aligned to track 210. Anti-tilt wheels 319 keep motorized trolley assembly 310, and therefore MACC 300 as a whole, from tilting horizontally when load-shifting occurs.

[0100] In some embodiments, wheel clean-sweep plates 311 are mounted on either or both sides of MACC 300 of some, if not all, load wheels assemblies 320 and provide for continuous removal of obstructions or debris that can accumulate on rail 205. In some embodiments, wheel clean-sweep plate 311 as a whole, or just the portion that moves over rail 205, can be made of a replaceable and serviceable high-density, synthetic material to remove obstructions. In some embodiments, wheel clean-sweep plate 311 is made of a steel plate.

In certain embodiments, these power buss(es) can have corresponding and aligned power pick-up shoes on each motorized trolley assembly 310 for power transfer into the motors and / or for feeding regenerated power back into the system during deceleration, braking and track decline sections.

[0102] Body 330 is connected to motorized trolley assemblies 310. In some embodiments, body 330 is connected to motorized trolley assemblies 310 via kingpin(s) 316 (see FIG. 18) and cross beam connector 313. This configuration allows for easy replacement of motorized trolley assemblies 310.

[0103] Kingpin(s) 316 can include a ball swivel top flange, designed with a thrust bearing, configured for descending through from the top, and out the bottom, of cross beam connector 313. Kingpins 316 can rotate within the allotted passageway and can have the ability to absorb vertical and lateral forces. In some embodiments, the lower end of kingpins 316 can have a full-circle, eyelet-designed bracket through which a secondary pin is placed, thus joining it with the top of body 330. This configuration allows the system to be readily hooked and unhooked for service and maintenance.

[0104] In other embodiments, body 330 is directly connected to motorized trolley assemblies 310. This direct connection can be accomplished by, among other things, a steel universal joint, a steel eyelet-to-eyelet, or a steel hook-to-eyelet connection.

[0105] The bumpers 340 are attached to body 330. In some embodiments, bumpers 340 are symmetrically designed since MACC 300 can operate bi-directionally.

In certain embodiments, bumpers 340 are configured so that containers being carried by separate MACC 300 cannot, or are at least less likely, to hit each other. Bumpers 340 also help reduce, if not eliminate, damage caused by collisions between multiple MACCs 300 and / or external objects.

[0106] The spacing created by bumpers 340, can also aid in maintaining safety-rated weight distribution on over-head track 210 and support structure when MACCs 300 are in an accumulated state.

[0107] In certain embodiments, bumpers 340 are attached to body 330 by a telescoping mechanism so their length from the center of body 330 can be adjusted depending on the length of container 220.

[0108] In some embodiments, trolleys 310 will move along the length of the body 330 to adjust for the different sizes of containers. Body 330 consists of tubular longitude members 380 that are supported by the end beams 350. The end beams 350 holes and brackets 362 allow it to slide along the tubular longitude members. There is a locking pin that secures the end beam into hole 321 for a first position for example 20 ft) position and hole 322 for a second position (for example, 40 ft).

[0109] In some embodiments, the sequence of operation for configuring MACC 300 to move a 20ft container to a 40ft container is as follows. A first trolley 310 can remove the self-seating locking pin from hole 321 and then move out from the center and slide on the tubular longitude member 380 while a second trolley 310 is stopped. When the first trolley 310 reaches the appropriate position, the self-seating locking pin can be inserted in hole 322. Next, the second trolley removes its self-seating locking pin from hole 321 and moves out from the center the track and slides on tubular longitude member 380 while the first trolley is stopped.
