Trailer stabilizer and restraint
A trailer restraining device comprising a portable frame having mounted thereto a tail hook and a king pin receiver that includes at least one of a receiver hydraulic cylinder, a receiver pneumatic cylinder, a receiver electric actuator, and a receive winch.
1. A method of verifying stabilization of a parked semi-trailer, the method comprising:
positioning a semi-trailer stabilizer underneath a forward portion of the parked semi-trailer, and toward a rear end of the parked semi-trailer, while at least two ground supports of the semi-trailer stabilizer are elevated above the ground, where the at least two ground supports are operatively coupled to one another via a cross-member and operatively coupled to at least one angled brace, where positioning the semi-trailer stabilizer includes positioning each of the at least two ground supports to be located on an opposing side of a longitudinal center plane of the parked semi-trailer;
repositioning the at least two ground supports, after the semi-trailer stabilizer is positioned underneath the forward portion of the parked semi-trailer, to cause the at least two ground supports to contact the ground, where at least a portion of the semi-trailer stabilizer extends beyond a footprint of the parked semi-trailer; and,
displaying a camera image, of a relative position of the semi-trailer stabilizer and the parked semi-trailer, on a visual display within an interior of a loading dock adjacent to the parked semi-trailer.
2. The method of claim 1 , further comprising:
mounting a camera to an exterior portion of the loading dock; and,
orienting the camera to allow capture of the camera image of the relative position of the semi-trailer stabilizer and the parked semi-trailer.
3. The method of claim 2 , wherein mounting the camera to the exterior portion of the loading dock includes positioning the camera to extend into the footprint of the parked semi-trailer when the parked semi-trailer is adjacent the loading dock.
4. The method of claim 2 , wherein mounting the camera to the exterior portion of the loading dock includes positioning the camera to extend underneath the parked semi-trailer when the parked semi-trailer is adjacent the loading dock.
5. The method of claim 1 , wherein positioning the semi-trailer stabilizer underneath the parked semi-trailer includes repositioning at least a portion of the semi-trailer stabilizer to contact with a forward-facing surface, facing away from the rear end, of the parked semi-trailer to inhibit further movement of the semi-trailer stabilizer toward the rear end of the parked semi-trailer.
6. The method of claim 5 , wherein:
the forward facing surface comprises a portion of a kingpin of the parked semi-trailer; and,
a kingpin receiver of the semi-trailer stabilizer contacts the kingpin to inhibit further movement of the semi-trailer stabilizer toward the rear end of the parked semi-trailer.
7. The method of claim 1 , further comprising the semi-trailer stabilizer concurrently engaging a kingpin of the parked semi-trailer and a ground anchor, where engaging the ground anchor includes repositioning a tailhook of the semi-trailer stabilizer from a stowed position, disengaged from the ground anchor, to a deployed position, engaged with the ground anchor.
8. The method of claim 1 , further comprising:
at least one of loading contents onto and unloading contents from the parked semi-trailer post visual verification that the semi-trailer stabilizer is underneath the forward portion of the parked semi-trailer; and,
communicating between the interior of the loading dock and an exterior of the loading dock, where communicating includes notifying external personnel at the loading dock that the parked semi-trailer has been at least one of loaded or unloaded.
9. The method of claim 1 , wherein the camera image comprises a video camera image.
10. The method of claim 1 , wherein repositioning the at least two ground supports includes raising wheels of the semi-trailer stabilizer with respect to the at least two ground supports.
11. A method of verifying stabilization of a parked semi-trailer at a loading facility, the method comprising:
positioning a semi-trailer stabilizer, including at least two repositionable ground mounts, underneath the parked semi-trailer so that the at least two repositionable ground mounts are elevated above the ground;
repositioning the at least two repositionable ground mounts to engage the ground; and,
displaying, on a visual display within the loading facility, a camera image of a relative position of the semi-trailer stabilizer and the parked semi-trailer.
12. A trailer stabilizing system comprising:
a repositionable semi-trailer stabilizer including:
first and second ground supports operatively coupled to one another via a cross-member, at least one of the first and second ground supports being operatively coupled to an angled brace;
a first semi-trailer stop configured to engage, in a first direction, a horizontal surface of a parked semi-trailer to support at least a portion of a forward weight of the parked semi-trailer;
a second semi-trailer stop configured to engage, in a second direction, a vertical surface of the parked semi-trailer to retard horizontal repositioning of the repositionable semi-trailer stabilizer in the second direction;
a plurality of wheels operatively coupled to the first and second ground supports;
a camera remote from the repositionable semi-trailer stabilizer; and,
a display remote from the repositionable semi-trailer stabilizer and configured to be communicatively coupled to the camera and display images based upon signals from the camera.
13. The trailer stabilizing system of claim 12 , wherein:
the first semi-trailer stop includes a first component extending above the first ground support, and a second component extending above the second ground support;
the first ground support is repositionably bolted to the first component to vary a height of the first semi-trailer stop with respect to the first ground support; and,
the second ground support is repositionably bolted to the second component to vary a height of the second semi-trailer stop with respect to the second ground support.
14. The trailer stabilizing system of claim 12 , wherein the first semi-trailer stop is laterally inset with respect to the first and second ground supports.
15. The trailer stabilizing system of claim 12 , wherein the repositionable semi-trailer stabilizer further includes a T-shaped handle operatively coupled to the first and second ground supports.
16. The trailer stabilizing system of claim 12 , wherein the first and second semi-trailer stops cooperate to form an L-shaped profile.
