Abstract

A parked freight trailer stabilizer and restraint comprising: (a) a kingpin receiver configured to lock onto a kingpin of a parked freight trailer; (b) a jack operatively coupled to the kingpin receiver, the jack repositionable between a retracted position and an extended position; (c) a tail hold operatively coupled to the kingpin receiver, the tail hold repositionable between a stowed position and a restraining position, the tail hold configured to engage a ground mount; and, (d) a transport receiver configured to engage a transport vehicle.

Claims

1. A method of at least one of stabilizing and restraining a parked freight trailer, the method comprising:

lifting a trailer stabilizing device to engage a parked freight trailer including locking onto a kingpin of the parked freight trailer, where at least a portion of the trailer stabilizing device is suspended above the ground occupying a footprint of the kingpin; and

,

repositioning a portion of the trailer stabilizing device to wedge the trailer stabilizing device between the ground and the parked freight trailer after lifting the trailer stabilizing device to engage the parked freight trailer and without requiring repositioning of a landing gear of the parked freight trailer.

2. The method of claim 1, wherein lifting the trailer stabilizing device to engage the parked freight trailer includes hanging a jack from the parked freight trailer so the jack is elevated above the ground in a hanging position.

3. The method of claim 2, wherein repositioning a portion of the trailer stabilizing device includes repositioning the jack from the hanging position to a ground mounting position where the jack engages the ground and assumes a load bearing capacity.

4. The method of claim 3, wherein:

the jack comprises a plurality of jacks; and

,

repositioning the plurality of jacks from the hanging position to the ground mounting position includes at least one of automatically and manually repositioning the plurality of jacks from the hanging position to the ground mounting position.

5. The method of claim 1, wherein lifting the trailer stabilizing device to engage the parked freight trailer includes hanging a tether from the parked freight trailer so the tether is elevated above the ground in a unengaged position.

6. The method of claim 5, wherein repositioning a portion of the trailer stabilizing device includes repositioning the tether from the unengaged position to an engaged position where the tether is concurrently operatively coupled to the ground and the forward portion of the parked freight trailer.

7. The method of claim 6, wherein:

the tether includes a tail hold; and

,

repositioning the tail hold from the unengaged position to the engaged position includes at least one of automatically and manually repositioning the tail hold.

26. The method of claim 1, further comprising:

using a video camera to generate video images depicted on a display located inside a loading dock to confirm a position of the trailer stabilizing device.

8. A method of at least one of stabilizing and restraining a parked freight trailer, the method comprising:

repositioning an elevated trailer stabilizing device off the ground and into engagement with a parked freight trailer including locking onto a kingpin of the parked freight trailer and suspending at least the portion of the trailer stabilizing device above the ground occupying a footprint of the kingpin, the trailer stabilizing device including a repositionable jack; and

,

repositioning the repositionable jack to wedge the stabilizing device between the parked freight trailer and the ground.

9. The method of claim 8, wherein the method does not include extension or retraction of landing gear of the parked freight trailer.

10. The method of claim 8, wherein:

the trailer stabilizing device further includes a repositionable tail hold; and

,

the method further includes repositioning the tail hold to engage a ground mount.

11. The method of claim 10, wherein the method does not include extension or retraction of landing gear of the parked freight trailer.

12. The method of claim 8, wherein:

the trailer stabilizing device further includes a repositionable tail hold; and

,

repositioning the trailer stabilizing device into engagement with a parked freight trailer include moving the tail hold across the ground.

13. The method of claim 8, wherein repositioning the elevated trailer stabilizing device into engagement with the parked freight trailer includes utilizing a forklift to reposition the elevated trailer stabilizing device.

14. The method of claim 8, wherein:

the trailer stabilizing device further includes a repositionable tail hold; and

,

the repositionable tail hold includes a metal frame repositionable with respect to the repositionable jack.

15. The method of claim 8 further comprising at least maintaining a height of forward portion of the parked freight trailer after repositioning the repositionable jack to wedge the stabilizing device between the parked freight trailer and the ground.

16. The method of claim 8, wherein repositioning the elevated trailer stabilizing device into engagement with the parked freight trailer includes utilizing pallet forks to reposition the elevated trailer stabilizing device.

27. The method of claim 8, further comprising:

using a video camera to generate video images depicted on a display located inside a loading dock to confirm a position of the trailer stabilizing device.

17. A method of at least one of stabilizing and restraining a parked freight trailer, the method comprising:

hanging a trailer stabilizing device from a forward aspect of a parked freight trailer;

repositioning a jack of the trailer stabilizing device to wedge the trailer stabilizing device between the parked freight trailer and the ground without requiring repositioning of a landing gear of the parked freight trailer; and

repositioning a tether of the trailer stabilizing device to engage a ground cleat.

18. The method of claim 17, wherein repositioning the tether to engage the ground cleat includes repositioning the tether from the unengaged position to an engaged position, where the engaged position is configured to place the tether in a tension between the ground cleat and the parked freight trailer.

19. The method of claim 18, wherein:

the tether includes a rigid tail hold; and

,

repositioning the tail hold from the unengaged position to the engaged position includes at least one of automatically and manually repositioning the tail hold.

20. The method of claim 17, wherein hanging the trailer stabilizing device from the forward aspect of the parked freight trailer includes coupling and suspending the trailer stabilizing device from a kingpin of the parked freight trailer.

21. The method of claim 17, wherein repositioning the jack of the trailer stabilizing device to wedge the trailer stabilizing device between the parked freight trailer occurs as the landing gear of the parked freight trailer are not repositioned.

22. The method of claim 17, wherein repositioning the jack of the trailer stabilizing device to wedge the trailer stabilizing device between the parked freight trailer includes reducing a load of the parked freight trailer borne by the landing gear.

23. The method of claim 17, wherein repositioning the jack of the trailer stabilizing device to wedge the trailer stabilizing device between the parked freight trailer includes sharing a load of the parked freight trailer between the landing gear and the jack.

24. The method of claim 17, further comprising:

using a video camera to generate video images depicted on a display located inside a loading dock to confirm a position of the trailer stabilizing device.

25. The method of claim 24, wherein the video camera is located outside of the loading dock.
