Trailer stabilization and restraint
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.
1. A parked semi-trailer stabilizer and restraint comprising:
a kingpin receiver configured to lock onto a kingpin of a parked semi-trailer;
a jack operatively coupled to the kingpin receiver, the jack repositionable between a retracted position and an extended position;
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,
a transport receiver configured to engage a transport vehicle.
2. The semi-trailer stabilizer of claim 1 , wherein the jack comprises at least two spaced apart jacks that are coupled to the kingpin receiver, where each of the at least two jacks is repositionable between the retracted position and the extended position.
3. The semi-trailer stabilizer of claim 2 , further comprising a frame mounted to the at least two spaced apart jacks.
4. The semi-trailer stabilizer of claim 3 , wherein the tail hold is repositionably mounted to at least one of the frame, the kingpin receiver, and the at least two spaced apart jacks.
5. The semi-trailer stabilizer of claim 1 , wherein the jack is manually repositionable between the retracted position and the extended position.
6. The semi-trailer stabilizer of claim 1 , wherein the jack is automatically repositionable between the retracted position and the extended position.
7. The semi-trailer stabilizer of claim 1 , wherein the transport receiver comprises a pair of fork receivers, each of the pair of fork receivers configured to receive a separate fork associated with the transport vehicle.
8. The semi-trailer stabilizer of claim 7 , wherein each of the pair of fork receivers comprises at least one of a hollow tube, a plurality of straps, a plurality of discontinuous bands.
9. The semi-trailer stabilizer of claim 1 , wherein the tail hold includes at least one of a bar and a hook that is configured to be mounted to the ground mount when in a restraining position, wherein the ground mount is permanently mounted to the ground.
10. The semi-trailer stabilizer of claim 1 , wherein the tail hold comprises a floating bar mounted to a frame, the floating bar configured to engage the ground mount when in a restraining position, wherein the ground mount is permanently mounted to the ground.
11. The semi-trailer stabilizer of claim 1 , wherein:
the jack includes a first handle that is rotationally repositionable to reposition the jack between the retracted position and the extended position; and,
the tail hold includes a second handle that is rotationally repositionable to reposition the tail hold between the stowed position and the restraining position.
12. The semi-trailer stabilizer of claim 1 , wherein:
the king pin receiver comprises a fifth wheel;
the jack comprises at least two jacks spaced apart from one another;
the tail hold includes a connector adapted to engage the ground mount in the restraining position; and,
the at least two jacks are semi-trailer load bearing jacks.
13. The semi-trailer stabilizer of claim 12 , wherein:
the tail hold is pivotally mounted to at least one of the fifth wheel and the at least two jacks;
the at least two jacks are at least one of manually and automatically repositionable; and,
the transport receiver comprises a pair of receivers, each of the pair of receivers configured to receive a projection of the transport vehicle.
14. The parked semi-trailer stabilizer and restraint of claim 1 , wherein:
the jack comprises a pair of jacks spaced apart and connected to one another via a cross-member;
the tail hold is mounted to the cross-member and extends in a direction generally opposite the transport receiver; and,
the kingpin receiver is mounted to the cross-member.
15. The parked semi-trailer stabilizer and restraint of claim 1 , wherein the kingpin receiver, when locked onto the kingpin, is operative to suspend the jack above the ground in the retracted position and suspend the tail hold above the ground when in the stowed position so that neither the jack nor the tail hold operatively engages the ground.
16. A parked semi-trailer stabilizer and restraint comprising:
a semi-trailer clamp configured to lock onto a parked semi-trailer;
a jack operatively coupled to the semi-trailer clamp, the jack repositionable between a retracted position and an extended position;
a tail hold operatively coupled to the semi-trailer clamp, the tail hold repositionable between a stowed position and a restraining position, the tail hold configured to engage a ground mount; and,
wherein the semi-trailer clamp, when locked onto the kingpin, is operative to suspend the jack above the ground in the retracted position and suspend the tail hold above the ground when in the stowed position so that neither the jack nor the tail hold operatively engages the ground.
17. The parked semi-trailer stabilizer and restraint of claim 16 , further comprising at least one fork passage.
18. The parked semi-trailer stabilizer and restraint of claim 17 , wherein the at least one fork passage is delineated by a pair of hollow tubes.
19. The parked semi-trailer stabilizer and restraint of claim 16 , further comprising a repositionable crank operatively coupled to at least one of the jack and the tail hold.
20. The parked semi-trailer stabilizer and restraint of claim 16 , wherein:
the jack comprises a pair of jacks spaced apart and connected to one another via a cross-member;
the tail hold is mounted to the cross-member; and,
the semi-trailer clamp is mounted to the cross-member.
