The apparatuses and methods disclosed herein may be pushed by hand or pulled by a motor vehicle. Thus, implementations of the transport device disclosed herein may have functions akin to a wheelbarrow or a dumping trailer, yet may provide easier and/or more efficient transportation and dumping functions over prior art wheelbarrows and dumping trailers. Implementation of the transport device disclosed herein also may be easier to push over an elevation or up a hill. Furthermore, in some implementations, the transport device disclosed herein includes four wheels and therefore can function like a cart. Still further, in some implementations, the transport device disclosed herein can have the functions of a wagon. In some implementations, the transport device includes a work bench.

1. A transport system comprising: a tub;a single longitudinal frame support to support the tub from an underside surface of the tub;a single lever arm extensible outwardly from the single longitudinal frame support; anda single upright handle coupled to the single lever arm and extended upwardly from the single lever arm;wherein the single longitudinal frame support, single lever arm, and single upright handle collectively form a single lift-arm, at least one fulcrum, and a single rail transport system. 2. The transport system of claim 1, further comprising: a hitching assembly, coupled to the single lever arm and with which to couple the transport device to a towing vehicle, the hitching assembly comprising: a hook;a gear mechanism;a shaft coupled to the gear mechanism and configured to turn the gear mechanism; anda shaft handle with which to rotate the shaft;wherein the hook is rotatable by operation of the shaft handle between an OPEN position to unhitch and a CLOSED position to tow. 3. The transport system of claim 2, wherein the single lever arm further comprises a V-shaped groove at a distal end, the V-shaped grove configured for receipt of a hitching pin to couple with the hitching assembly hook when engaged. 4. The transport system of claim 2, further comprising: a hitch configured to mount to a towing vehicle, the hitch configured to couple to the hitching assembly. 5. The transport system of claim 4, wherein the hitch further comprises: a main frame;a hitch pin disposed vertically within the main frame and operable to move up and down vertically and configured to be locked in an UP or DOWN position; and a control pin to control the vertical position of the hitch pin. 6. The transport system of claim 5, further comprising: a compression spring, with the hitch pin and control pin, configured to lock the hitch in an UP or DOWN position. 7. The transport system of claim 5, further comprising: a knob disposed upon the hitch pin and configured to be operably grasped to manipulate the hitch pin. 8. The transport system of claim 2, further comprising: a braking system comprising: at least one brake drum;at least one brake caliper;at least one control cable; anda tension spring coupled to the hitching assembly;wherein the at least one cable and tension spring are mechanically coupled and operation of a lever controls the at least one brake caliper. 9. The transport system of claim 1, further comprising: an adjustable handle assembly comprising: an adjustable two-arm handle;wherein the handle is a U or D-style, secondary handle supported on the single upright handle and is adjustable 360 degrees in 45-degree increments. 10. The transport system of claim 9, further comprising: a lock pin configured to lock the adjustable two-arm handle in place once adjusted to the, single upright handle. 11. The transport system of claim 1, further comprising: a tub-to-handle assembly locking key system configured to lock the single longitudinal frame support to the single lever arm when the transport system is used to transport material and also to unlock the single longitudinal frame support from the single lever arm so that the transport system may dump its contents. 12. The transport system of claim 11, the key system further comprising: a u-bracket;a handle having a distal end configured for placement through the u-bracket;a compression spring disposed around the distal end of the handle at a portion within the u-bracket; at least one rolled pin; andwherein a turn of the at least one rolled pin to align the at least one rolled pin allows insertion into a hole in the single lever arm and another turn locks the tub and a reverse turn unlocks the tub. 13. The transport system of claim 1, further comprising: a tailgate disposed on the tub and configured to swing open to unload contents from within the tub; andat least one closure device to secure the tailgate in place to the tub. 14. The transport system of claim 13, wherein the at least one closure device is configured to fasten the tailgate to a bed of the tub. 15. The transport system of claim 13, wherein the at least one closure device is configured to fasten the tailgate to two sides of the tub. 16. The transport system of claim 13, wherein the at least one closure device is a compression spring device configured to hold down the tailgate relative to the tub and to prevent the tailgate from opening unexpectedly. 17. The transport system of claim 1, further comprising: a swivel caster wheel disposed generally under the single upright handle;a pair of wheels, with a first of said wheels disposed on an exterior side of the transport system and a second of said wheels disposed on an opposing side, each wheel having a hub at its center; anda pair of rail slides, with a first of said rail slides disposed on an exterior side of the transport system and a second of said rail slides disposed an opposing side;wherein the first wheel is mounted to the first rail slide and is configured at its hub to slide about the first rail slide;wherein the second wheel is mounted to the second rail side and is configured at its hub to slide about the second rail slide; and wherein as the first and second wheels slide about the first and second rail slides, a center-of-gravity point relative to the wheels is relocated;thereby as the first wheel and second wheel are counter-levered toward a rear of the transport system, it serves to move a center of gravity, take weight off of the swivel caster wheel, and to increase a leverage and a mechanical advantage of the transport system. 18. The transport system of claim 17, wherein the transport system is configured for operator use as needed to shift weight, and the center of gravity, balanced between the swivel caster wheel and the first wheel and second wheel thereby to transition between use needs with increased leverage and mechanical advantage or transport system stability. 19. The transport system of claim 1, further comprising: a pair of dumping wheels disposed on the single lever arm and configured to facilitate a dumping action as the wheels make contact with the ground and facilitate pivoting of the single lever arm. 20. The transport system of claim 1, further comprising: dual fulcrum pivot lines for both first class and second class lever systems.
