Abstract

A trailer stabilizing device for stabilizing a parked freight trailer comprising a frame having mounted thereto at least a right side wheel and a left side wheel, the frame also including a hitch, a fifth wheel, and at least one of a repositionable wheel chock and a repositionable hook, the trailer stabilizing device further including a repositioning device in order to reposition at least one of the repositionable wheel chock and the repositionable hook. The present disclosure also includes a method of stabilizing a parked trailer at a loading dock, the method comprising: (a) positioning a wheeled trailer stabilizer underneath a parked freight trailer at a loading dock while landing gear of the parked freight trailer are deployed and a kingpin of the parked trailer is accessible; (b) securing the kingpin of the parked freight trailer to a fifth wheel of the wheeled trailer stabilizer; and, (c) deploying a repositionable hook operatively coupled to the frame of the wheeled trailer stabilizer so the repositionable hook couples to a cleat mounted to the ground, where deployment of the hook is operative to exert a pulling force on the kingpin.

Claims (47)

1. A trailer stabilizing device comprising:

a frame having a pair of frame members operatively coupled to wheels, the pair of frame members coupled to one another by at least one cross-member, the frame members being operatively coupled to a fifth wheel, a front end of the frame includes a hitch, and an arm mounted to the frame extends outward from a rear end of the frame, the arm having a first portion pivotally mounted to the frame and a second portion including a hook adapted to interface with a ground cleat, the arm being operatively coupled to a repositioning device operative to pivot the arm with respect to the frame, and an on-board controller for receiving signals from a sensor that at least one of a kingpin is secured to the fifth wheel and the hook is engaged with the ground cleat, the controller including a wireless transmitter for transmitting a signal to a receiver indicating at least one of the kingpin is secured to the fifth wheel and the hook is engaged with the ground cleat.

2. The trailer stabilizing device of claim 1 , further comprising a repositionable wheel chock operatively coupled to the frame by way of a second repositioning device.

3. The trailer stabilizing device of claim 2 , wherein:

the repositionable wheel chock comprises a first repositionable wheel chock and a second repositionable wheel chock;

the first repositionable wheel chock is repositionable to contact a first of the wheels; and,

the second repositionable wheel chock is repositionable to contact a second of the wheels.

4. The trailer stabilizing device of claim 2 , wherein:

the second repositioning device includes a hydraulic cylinder operatively coupled to the frame; and

the hydraulic cylinder is in communication with a fluid line coupled to at least one of a glad hand and a fluid tank.

5. The trailer stabilizing device of claim 2 , wherein:

the second repositioning device includes a pneumatic cylinder operatively coupled to the frame; and, the pneumatic cylinder is in communication with a fluid line coupled to at least one of a glad hand and a fluid tank.

6. The trailer stabilizing device of claim 2 , wherein the second repositioning device includes at least one of a pneumatic cylinder, a hydraulic cylinder, a winch, an airbag, and a jack.

7. The trailer stabilizing device of claim 1 , wherein the repositioning device includes at least one of a pneumatic cylinder, a hydraulic cylinder, a winch, an airbag, and a jack.

8. The trailer stabilizing device of claim 1 , wherein:

the repositioning device includes a hydraulic cylinder operatively coupled to the frame; and

the hydraulic cylinder is in communication with a fluid line coupled to at least one of a glad hand and a fluid tank.

9. The trailer stabilizing device of claim 1 , wherein:

the repositioning device includes a pneumatic cylinder operatively coupled to the frame; and,

the pneumatic cylinder is in communication with a fluid line coupled to at least one of a glad hand and a fluid tank.

10. The trailer stabilizing device of claim 1 , wherein the receiver is communicatively coupled to a visual display.

11. The trailer stabilizing device of claim 10 , wherein:

the wireless transmitter includes an infrared light source emitting an infrared light;

the receiver comprises an infrared receiver;

the receiver is communicatively coupled to the visual display.

12. The trailer stabilizing device of claim 11 , wherein including a red light and a green light that are configured to be selectively illuminated.

13. The trailer stabilizing device of claim 1 , wherein:

the wireless transmitter includes an infrared light source emitting an infrared light; and,

the receiver comprises an infrared receiver.

14. A trailer stabilizing device comprising a frame mounted a portable ground carriage and a repositionable hook, the repositionable hook operatively coupled to a repositioning device in order to raise and lower the repositionable hook with respect to the frame, and a controller communicatively coupled to a signaler associated with the trailer stabilizing device for signaling a status of the trailer stabilizing device with respect to a parked freight trailer, wherein:

the signaler includes a light source emitting a light;

the signaler is communicatively coupled to a signal receiver;

the signal receiver is communicatively coupled to a visual display.

15. The trailer stabilizing device of claim 14 , wherein the repositioning device includes at least one of a pneumatic cylinder, a hydraulic cylinder, a winch, an airbag, and a jack.

16. The trailer stabilizing device of claim 14 , wherein:

the repositioning device includes a hydraulic cylinder operatively coupled to the frame; and

the hydraulic cylinder is in communication with a fluid line coupled to a glad hand.

17. The trailer stabilizing device of claim 14 , wherein:

the light source includes an infrared light source;

the light includes an infrared light; and,

the signal receiver comprises an infrared receiver.

18. The trailer stabilizing device of claim 14 , wherein the visual display includes a red light and a green light that are configured to be selectively illuminated.

19. The trailer stabilizing device of claim 14 , further comprising:

a kingpin sensor configured to detect a kingpin of the parked freight trailer;

wherein the kingpin sensor is communicatively coupled to the controller.

20. The trailer stabilizing device of claim 14 , further comprising a hook sensor configured to detect a position of the repositionable hook, wherein the hook sensor is communicatively coupled to the controller.

21. The trailer stabilizing device of claim 14 , further including a switch in electrical communication with a power source onboard the trailer stabilizing device for providing selective power to the controller.
