A hydraulic lifting mechanism for a large vehicle trailer comprises a square tubular metallic frame having a base and an upright support structure. A pair of pivoting wheels are disposed at a first base side of the base while a pair of wheels upon an axle are disposed upon a second base side of the base opposite the pivoting wheels. A four armed hydraulic lift is secured upon the upright support structure. At a distal end of the four armed hydraulic lift is a trailer hitch ball. The device is removably securable to a tractor.

A remote-controlled lifting and maneuvering device and a process of remotely controlling a trailer maneuvering device by use of a remote control is provided. The remote-controlled lifting and maneuvering device allows a single operator to both raise and lower the tongue of a trailer, and maneuver a trailer without having to apply physical force to the trailer or maneuver a towing vehicle. The lifting mechanism may be achieved using a hydraulic jack component, an electrical jack or other actuating component. The movement and maneuverability of the device may be achieved using a maneuvering system. This combination of a jack component and maneuvering system may be adapted for maneuvering a trailer into position, raising the trailer to an appropriate height, and finally lowering the trailer for affixing to a towing vehicle.

A trailer stabilizing device for stabilizing a parked freight trailer comprising a frame having mounted thereto at least a right side wheel and a left side wheel, the frame also including a hitch, a fifth wheel, and at least one of a repositionable wheel chock and a repositionable hook, the trailer stabilizing device further including a repositioning device in order to reposition at least one of the repositionable wheel chock and the repositionable hook. The present disclosure also includes a method of stabilizing a parked trailer at a loading dock, the method comprising: (a) positioning a wheeled trailer stabilizer underneath a parked freight trailer at a loading dock while landing gear of the parked freight trailer are deployed and a kingpin of the parked trailer is accessible; (b) securing the kingpin of the parked freight trailer to a fifth wheel of the wheeled trailer stabilizer; and, (c) deploying a repositionable hook operatively coupled to the frame of the wheeled trailer stabilizer so the repositionable hook couples to a cleat mounted to the ground, where deployment of the hook is operative to exert a pulling force on the kingpin.
