Abstract

A low profile transport device includes a frame having a top surface and a recess disposed along the top surface to hold and transport an object. The low profile transport device also includes a plurality of wheels disposed below the frame that support the frame, and a plurality of pivotable wheel struts coupled to the wheels. The wheel struts are each individually adjustable relative to the frame from a first position relative to the frame to a second position relative to the frame to allow the low profile transport device to climb an obstacle without tilting the frame. The low profile transport device also includes a motor that generates movement of the wheels.

First claim

What is claimed is:

1. A low profile transport device comprising:
a frame having a top surface and a recess disposed along the top surface to hold and transport an object;
a plurality of wheels disposed below the frame that support the frame;
a plurality of pivotable wheel struts coupled to the wheels, wherein each wheel strut is coupled to exactly one wheel such that the number of wheel struts equals the number of wheels, wherein the wheels and the wheel struts form an independent suspension, such that the wheel struts are each individually adjustable relative to the frame, from a first position relative to the frame to a second position relative to the frame to allow the low profile transport device to climb an obstacle without tilting the frame; and
a motor that generates movement of the wheels.

2. The low profile transport device of claim 1 , further comprising a controller in communication with the motor, wherein the controller is configured to independently control the steering of each wheel and to generate articulated steering of the wheels.

3. The low profile transport device of claim 2 , wherein the motor generates the movement of the wheels based on signals received at the controller.

4. The low profile transport device of claim 2 , wherein the motor generates pressure in an operating medium for the adjustment of the wheel struts, based on signals received at the controller.

5. The low profile transport device of claim 2 , wherein the articulated steering includes at least one of crab, circle, or proportional steering.

6. The low profile transport device of claim 1 , further comprising an hydraulic or pneumatic connector disposed along an outer surface of the frame, wherein the hydraulic or pneumatic connector directs operating medium to the wheel struts.

7. The low profile transport device of claim 1 , wherein each of the wheels is comprised of solid steel with polyurethane tread.

8. The low profile transport device of claim 1 , wherein the plurality of wheels includes eight wheels, and wherein the plurality of wheel struts includes eight wheel struts.

9. The low profile transport device of claim 1 , wherein each of the wheel struts is individually adjustable at least eight inches relative to the frame.

10. The low profile transport device of claim 1 , further comprising a plurality of tie-down shackles disposed along the top surface to secure an object within the recessed area.

11. The low profile transport device of claim 1 , wherein the frame is rectangular, wherein the recess forms a well along a top of the frame to receive a nuclear cask, and wherein the low profile transport device further comprises a cable reel coupled to the frame.

12. The low profile transport device of claim 1 , wherein the wheel struts are each individually adjustable relative to the frame via hydraulics or pneumatics.

13. The low profile transport device of claim 1 , wherein the low profile transporter device conforms to ASME NOG-1-2004.

14. The low profile transport device of claim 1 , wherein each wheel strut is pivotable to permit turning and steering of the low profile transporter device.

15. A system for transporting a cask comprising:
a cask transport device including:
a support assembly including a plurality of support assembly wheels and a support frame coupled to and supported by the support assembly wheels;
a tower disposed above the support assembly;
an upper beam assembly coupled to the tower frame;
a bottom block assembly coupled to the upper beam assembly, the bottom block assembly movable from a first vertical position relative to the upper beam assembly to a second vertical position relative to the upper beam assembly; and
a controller; and

the low profile transport device of claim 1 , wherein the low profile transport device includes a controller, wherein the controller on the low profile transporter and the controller on the cask transport device are each configured such that movement of the low profile transport device is controlled via the controller on the cask transport device.

16. The system of claim 15 , wherein the controller of the low profile transport device is in communication with the motor, wherein the controller on the low profile transport device is configured to independently control the steering of each wheel and to generate articulated steering of the wheels.

17. The system of claim 16 , wherein the motor of the low profile transport device generates the movement of the wheels on the low profile transport device based on signals received at the controller on the low profile transport device from the controller on the cask transport device.

18. The system of claim 16 , wherein the motor of the low profile transport device generates hydraulic or pneumatic pressure for the adjustment of the wheel struts on the low profile transport device, based on signals received at the controller on the low profile transport device from the controller on the cask transport device.

19. The low profile transport device of claim 16 , wherein the articulated steering includes at least one of crab, circle, or proportional steering.

20. The system of claim 15 , wherein the low profile transport device includes an hydraulic or pneumatic connector disposed along an outer surface of the frame of the low profile transport device, wherein the hydraulic or pneumatic connector directs operating medium to the wheel struts on the low profile transport device.

21. The system of claim 20 , wherein cask transport device includes a source of the operating medium, such that the operating medium is movable from the cask transport device to the low profile transport device via the hydraulic or pneumatic connector.

22. The system of claim 15 , wherein the plurality of wheels on the low profile transport device includes eight wheels, and wherein the plurality of wheel struts on the low profile transport device includes eight wheel struts.

23. The system of claim 15 , wherein each of the wheel struts on the low profile transport device is individually adjustable at least eight inches relative to the frame of the low profile transport device.

24. The system of claim 15 , further comprising a plurality of tie-down shackles disposed along the top surface of the low profile transport device to secure an object within the recessed area.

25. The system of claim 15 , wherein each of the wheels comprises solid steel with a polyurethane tread.
