Trailer docking repositionable support
First Claim
1. A trailer stabilizing device comprising a frame operatively coupled to wheels, a kingpin receiver operatively coupled to the frame, a repositionable tailhook operatively coupled to the frame, a hitch operatively coupled to the frame and utilized for portably repositioning the trailer stabilizing device, and an on-board controller configured to receive a signal from a sensor that at least one of a kingpin is received by the kingpin receiver and the repositionable tailhook engages a ground cleat, wherein the repositionable tailhook extends in a proximal direction, and the hitch extends in a distal direction, generally opposing the proximal direction, and wherein the on-board controller includes a wireless transmitter configured to transmit a signal to a receiver indicating at least one of the kingpin is received by the kingpin receiver and the repositionable tailhook engages the ground cleat.

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.

- 14. A trailer stabilizing device comprising a frame operatively coupled to wheels, a kingpin receiver, a tailhook repositionable with respect to the frame between a disengaged ground position and an engaged ground position, and an on-board controller configured to receive a signal from a sensor that the tailhook is in at least one of the ground engaged position and the ground disengaged position, wherein the on-board controller includes a wireless transmitter configured to transmit a signal to a receiver indicating the tailhook is in at least one of the ground engaged position and the ground disengaged position.
- 19. A trailer stabilizing device comprising a frame operatively coupled to wheels, a kingpin receiver, a tailhook repositionable with respect to the frame between a disengaged ground position and an engaged ground position, and an on-board controller configured to receive a signal from a sensor that at least one of a kingpin is received by the kingpin receiver and the repositionable tailhook engages a ground cleat, wherein the on-board controller includes a wireless transmitter configured to transmit a signal to a receiver indicating at least one of the kingpin is received by the kingpin receiver and the repositionable tailhook engages the ground cleat.
- 24. A trailer stabilizing device comprising a frame operatively coupled to wheels, a kingpin receiver operatively coupled to the frame, a repositionable tailhook operatively coupled to the frame, a hitch operatively coupled to the frame and utilized for portably repositioning the trailer stabilizing device, wherein the repositionable tailhook extends in a proximal direction and is repositionable with respect to the frame between a disengaged ground position and an engaged ground position, and the hitch extends in a distal direction, generally opposing the proximal direction, and an on-board controller configured to receive a signal from a sensor that the tailhook is in at least one of the ground engaged position and the ground disengaged position, wherein the on-board controller includes a wireless transmitter configured to transmit a signal to a receiver indicating the tailhook is in at least one of the ground engaged position and the ground disengaged position.
