A method of stabilizing a parked semi-trailer, the method comprising:
- positioning a frame, separate from a support frame of the parked semi-trailer, underneath a forward portion of the parked semi-trailer, where the frame includes a semi-trailer load bearing repositionable jack, and the frame has mounted thereto a wheel;
- floating the semi-trailer load bearing repositionable jack with respect to the wheel using a spring concurrently operatively coupled to the wheel and to the semi-trailer load bearing repositionable jack, where a first spring load is applied to the spring when the semi-trailer load bearing repositionable jack is floating;
- and,
- decreasing the first spring load on the spring by deploying the semi-trailer load bearing repositionable jack in a second position to wedge at least one of the frame and the semi-trailer load bearing repositionable jack between the ground and an underside of the parked semi-trailer;

A method of stabilizing a parked semi-trailer, the method comprising:
- floating a semi-trailer load bearing repositionable jack with respect to a wheel operatively coupled to a frame of a trailer stabilizing device using a passive suspension, where the trailer stabilizing device is separate from a support frame of the parked semi-trailer;
- wedging the trailer stabilizing device between the ground and the parked semi-trailer;
- and,
- continuing to float the semi-trailer load bearing repositionable jack with respect to the wheel so that a load on the passive suspension decreases as a load borne by the semi-trailer load bearing repositionable jack increases.
1 more element
A method of stabilizing a parked semi-trailer, the method comprising:
- deploying a first and second semi-trailer load bearing repositionable jacks in a first direction to contact the ground, the first and second semi-trailer load bearing repositionable jacks comprising a portion of a semi-trailer stabilizing device that also includes a semi-trailer plate and a frame separate from a support frame of the parked semi-semi-trailer, the stabilizing device frame having mounted thereto an axle and at least two wheels mounted to the axle;
- deploying the semi-trailer plate in a second direction opposite the first direction to engage the parked semi-semi-trailer;
- wherein the first and second semi-trailer load bearing repositionable jacks are operatively coupled to a spring that is operatively coupled to the axle and the at least two wheels, the spring is configured to allow the first and second semi-trailer load bearing repositionable jacks to float with respect to the axle and the at least two wheels, wherein the first and second semi-trailer load bearing repositionable jacks include a drive shaft extending therebetween, where at least a portion of the drive shaft extends on opposing sides of at least one of the first and second semi-trailer load bearing repositionable jacks, and where the frame includes a frame rail extending parallel to the drive shaft and the axle, and where the frame rail extends perpendicular to the first and second semi-trailer load bearing repositionable jacks
