Tactical transport cart for manual navigation over both topographic and hydrographic terrains

1. A tactical transport cart configured to be navigable over both ground surfaces of topographic terrains and water-covered surfaces of hydrographic terrains, the transport cart comprising:

a frame having an open structure formed by a pair of laterally spaced-apart longitudinally-extending frame members,

a cart body centrally affixed and extending downwardly from the frame members defining a lower enclosure within the cart body,

a payload support affixed to the frame at an upper side of the cart body defining a payload-supporting area on the frame,

a port configured for power export,

a pair of terrain-engaging transport propulsion members attached to the frame in laterally spaced relation for supporting the frame at an elevation above surrounding terrain,

a handle structure attached to the frame and extending therefrom in orthogonal relation to the transport propulsion members,

at least one motor connected in driving relation to the transport propulsion members,

a battery for providing motive power to the motor,

a control device operatively connected between the battery and the motor for controlling supply of motive power to the motor,

the handle structure being configured for steering movement of the frame over surrounding terrain while enabling simultaneous selective access to and operation of the control device,

the frame, transport propulsion members and handle structure being cooperatively dimensioned and configured for movement of the cart over ground surfaces of topographic terrains and for partially and fully submerged movement over water-covered surfaces of hydrographic terrains,

the motor, the battery, the control device and connections therebetween being sealed against water intrusion during submerged operation, and

wherein the at least one motor is mounted within a lowermost region of the lower enclosure.

2. The tactical transport cart according to claim 1 , wherein the transport device comprises a ballistic shield or ballistic protection device.

3. The tactical transport cart according to claim 1 , wherein the payload support is elevatable.

4. The tactical transport cart according to claim 1 , wherein the payload support is a platform or a cloth.

5. The tactical transport cart according to claim 1 , wherein the handle structure is rotatable.

6. The tactical transport cart according to claim 1 , wherein the handle structure telescopes, swings, or extends.

7. The tactical transport cart according to claim 1 , wherein the tactical transport cart further comprises a stabilizing prop or support leg attached to the frame.

8. The tactical transport cart according to claim 1 , wherein the tactical transport cart further comprises a manually selectable hub on a wheel of the tactical transport cart.

9. The tactical transport cart according to claim 1 , wherein the tactical transport cart is collapsible into a case.

10. The tactical transport cart according to claim 1 , wherein the tactical transport cart further comprises a sealed electrical enclosure.

11. The tactical transport cart according to claim 1 , wherein the port is operatively connected to a powertrain in the tactical transport cart.

12. The tactical transport cart according to claim 1 , further comprising a hard point of attachment or connection to the frame or payload support.

13. The tactical transport cart according to claim 12 , wherein the hard point of attachment or connection is a logistics track.

14. The tactical transport cart according to claim 1 , wherein the port is configured for transmission or receipt of a signal.

15. The tactical transport cart according to claim 1 , wherein the tactical transport car comprises an on and off power failsafe.
