A method of stabilizing a kingpin comprising the steps of:
- providing a kingpin stabilizer with a retaining bracket and a leg portion, the retaining bracket being defined by one or more walls extending upwardly from a baseplate to create a receiving cavity and at least one opening, one or more of the retaining bracket walls terminating with a kingpin retainer extending into the receiving cavity;
- and
- slideably engaging the retaining bracket onto the kingpin by inserting the kingpin through the opening and into the receiving cavity;
- and
- extending the leg portion of the kingpin stabilizer to contact a support surface.
A trailer stabilizing assembly comprising:
- a trailer kingpin comprising a main body that extends downward from a bottom surface of a stationary trailer into a flanged lower end;
- a retaining bracket that engages the kingpin flange and comprising a baseplate and a receiving cavity, the receiving cavity is defined by one or more walls extending upwardly from a periphery of the baseplate, at least one of the walls having an offset kingpin retainer that extends into the receiving cavity;
- and
- one or more downwardly extending legs operatively connected to the retaining bracket.
A trailer stabilizing assembly comprising:
- a kingpin extending downward from the bottom surface of a stationary trailer, the kingpin having a main body attached at a first end to the bottom surface of the trailer and a flanged second end;
- and
- a stabilizer unit comprising a kingpin retaining bracket and a plurality of support legs, the retaining bracket having a baseplate, a wall extending a substantial distance around a periphery of the baseplate and upward therefrom, and an opening in the wall, the wall further comprising an inward facing flange along at least a part of its length, and the stabilizing unit releasably engaging the kingpin by passing the kingpin flange through the opening in the retaining bracket wall.
