SEMI-TRAILER REPOSITIONER
First Claim
1. An apparatus for repositioning a semi-trailer, comprising:
- two hydraulic jack arms, each comprising a hydraulic cylinder containing a movable piston;
an upper frame attached to an underside area of the semi-trailer, wherein the hydraulic jack arms are pivotally attached to the upper frame, further wherein the hydraulic jack arms are disposed substantially parallel to the upper frame and are disposed to be pivoted away from the upper frame to a position substantially perpendicular to the upper frame;
two opposing wheels, each coupled to a wheel housing, wherein each wheel is operatively coupled to a motor;
a lower frame with opposing ends, with each of the ends attached to one of the wheel housings, the lower frame being mounted to the movable pistons of the hydraulic jack arms;
wherein, lowering the hydraulic jack arms can hydraulically lift the semi-trailer, and further wherein the wheels can maneuver the semi-trailer.

Abstract
Exemplary apparatus and system for repositioning a semi-trailer are described. The repositoner may comprise two pivoting arms, each comprising a mechanical actuator attached to an underside area of the semi-trailer, wherein the pivoting arms are disposed substantially parallel to the underside of the semi-trailer in a first position and are configured to be pivoted away from the semi-trailer in a second position substantially perpendicular to the underside of the semi-trailer; two wheels mounted at an angle from a rear plane of the semi-trailer such that the semi-trailer moves in a circular path when the wheels turn, with each wheel operatively coupled to a motor; and a lower frame mounted to the mechanical actuators of the arms, the lower frame comprising two opposing wheel housing couple to the wheels; wherein, lowering the hydraulic jack arms can hydraulically lift the semi-trailer, and further wherein the wheels can maneuver the semi-trailer.
