Abstract

A transport vehicle includes a power unit, an attachment accessory, and an attachment mechanism configured to removably attach the attachment accessory to the power unit.

Claims

1. A transport vehicle comprising:

a power unit including a plurality of wheels;

an attachment accessory; and

an attachment mechanism configured to removably attach the attachment accessory to the power unit.

2. The transport vehicle of claim 1, wherein the power unit includes a frame, a power supply, and the plurality of wheels coupled to the frame, with the power supply operatively coupled to at least two of the wheels.

3. The transport vehicle of claim 2, wherein the power supply includes two motors, with each motor operatively coupled to one wheels such that the vehicle can perform zero-radius turns.

4. The transport vehicle of claim 1, wherein the power unit has a width of approximately 28 inches or less.

5. The transport vehicle of claim 1, wherein the attachment accessory includes a platform and an enclosure for supporting a person at an elevated height.

6. The transport vehicle of claim 5, wherein the enclosure includes a height adjustment mechanism that permits a top rail of the enclosure to be moved between a lowered configuration and at least one raised configuration.

7. The transport vehicle of claim 1, wherein the attachment accessory includes a dump box that is pivotally mounted to the power unit.

8. The transport vehicle of claim 1, wherein the attachment mechanism includes a post that extends from a central region of the frame.

9. The transport vehicle of claim 8, wherein the attachment mechanism further includes a locking mechanism to retain the attachment accessory in a stationary position on the power unit.

10. The transport vehicle of claim 1, wherein the attachment mechanism includes a pair of guide plates attached to an upper surface of the power unit to provide a slot therebetween, and an elongated shaft that extends from a lower surface of the attachment accessory, wherein the elongated shaft has a width that generally conforms to a distance between the pair of guide plates.

11. The transport vehicle of claim 10, wherein the attachment mechanism further includes a plate attached to a lower end of the elongated shaft, the plate having a width that is greater than a width of the elongated shaft and that is wider than a distance between the guide plates.

12. The transport vehicle of claim 10, wherein each of the guide plates has a channel formed therein.

13. The transport vehicle of claim 10, further comprising a lock mechanism mounted with respect to the guide plates to maintain the elongated shaft in a desired position with respect to the guide plates.

14. A transport vehicle comprising:

a frame;

a power supply;

at least six wheels coupled to the frame, with a front pair of wheels, a middle pair of drive wheels, and a rear pair of wheels, with the power supply operatively coupled to the middle pair of drive wheels, wherein the power supply includes two motors and each motor is operatively coupled to one of the drive wheels such that the vehicle can perform zero-radius turns;

an attachment accessory; and

an attachment mechanism configured to removably attach the attachment accessory to the power unit.

15. The transport vehicle of claim 14, wherein the attachment accessory includes a platform and an enclosure for supporting a person at an elevated height.

16. The transport vehicle of claim 14, wherein the attachment accessory includes a dump box that is pivotally mounted to the power unit.

17. The transport vehicle of claim 14, wherein the attachment mechanism includes a post that extends from a central region of the frame.

18. The transport vehicle of claim 14, wherein the attachment mechanism includes a pair of guide plates attached to an upper surface of the power unit to provide a slot therebetween, and an elongated shaft that extends from a lower surface of the attachment accessory, wherein the elongated shaft has a width that generally conforms to a distance between the pair of guide plates.

19. The transport vehicle of claim 18, wherein the attachment mechanism further includes a plate attached to a lower end of the elongated shaft, the plate having a width that is greater than a width of the elongated shaft and that is wider than a distance between the guide plates.

20. A method comprising:

providing a power unit including a plurality of wheels;

selectively choosing one of a plurality of attachment accessories; and

removably attaching the chosen attachment accessory to the power unit.
