A parked freight trailer stabilizer and restraint comprising: (a) a kingpin receiver configured to lock onto a kingpin of a parked freight trailer; (b) a jack operatively coupled to the kingpin receiver, the jack repositionable between a retracted position and an extended position; (c) a tail hold operatively coupled to the kingpin receiver, the tail hold repositionable between a stowed position and a restraining position, the tail hold configured to engage a ground mount; and, (d) a transport receiver configured to engage a transport vehicle.

Described herein are systems and methods for storing moveable vessels, such as RVs, trailers, and boats, in a level position on any type of storage surface (e.g., sloped driveway, uneven ground). Such vessels may continue to operate properly and/or may not become damaged. A vessel support system for supporting a moveable vessel can include a base and a leg that is coupled to and extending from the base. The leg can pivot relative to the base and can be fixedly supported at the base in at least one position. The leg can engage a hitch coupler of the moveable vessel, and the leg can, based on the base being positioned at a sloped surface, extend vertically to thereby support the moveable vessel at the hitch coupler of the moveable vessel. An extendable portion can also attach to the leg and extend to different lengths to support vessels of different heights.

Disclosed are embodiments of motor mounts for attaching a motor to an input shaft of trailer landing gear. One embodiment of the motor mount has an L-shaped frame bracket having first and second plates at right angle. The first plate is secured to a frame part of the trailer. The motor mount also has an L-shaped motor bracket having first and second plates at a right angle. The motor bracket first plate has an opening therethrough. The motor bracket second plate is secured to the frame bracket second plate. A gearbox is operatively connected to the electric motor and is secured to the motor bracket first plate. The gearbox has an outwardly extending drive mechanism that extends through the opening in the motor bracket first plate and connects to the landing gear input shaft. Another embodiment is a Z-shaped motor mount that includes first, second, and third plates.

The present invention discloses a trailer connector sleeve lock, comprising a lock cover, a lock tongue piece and a lock hole plate, wherein the lock hole plate is rotatably installed on the lock cover and is provided with a lock hole, and the lock hole plate rotates to the lock cover to serve as the side wall of the lock cover, they are spliced together to form a sleeve lock structure, wherein an opening is arranged above the sleeve lock structure, and the opening is smaller than the size of the lock tongue piece, wherein the lock tongue piece is provided with a lock tongue and is clamped in the sleeve lock structure, wherein the lock tongue extends out of the lock hole and is fixed through an additional lock. The advantageous effects of the present invention are that: the lock cover and the lock hole plate are spliced into a sleeve lock structure, and then the lock tongue piece is clamped in the sleeve lock structure, the lock tongue in the lock tongue piece extends out of the lock hole plate, and then the trailer is locked in such a manner that the lock tongue is fixed by the additional lock, and the installation is convenient. The four sides of the lock tongue piece are completely covered by the lock cover, and the lock tongue is inserted into the lock hole plate, so that a thief cannot damage the sleeve lock by cutting the lock tongue. The damage difficulty is high, the time-consuming is long, and the protection effect is good.

A trailer jack and transport system providing improved rolling and steerable motion to sport, recreational and utility trailers, when operating on diverse kinds of ground surfaces, including pavement, dirt, sand, and mud, without use of caster-style wheels. The trailer jack and transport system employs a spherical load-bearing transport ball supported within a frame assembly and configured to allow the spherical wheel to freely rotate in any orientation, on ground surfaces of a diverse nature during system operation.

A walking trailer stand including a mobile trailer assembly, a trailer stand assembly, and a reversible feet assembly is disclosed. These assemblies allow for the manually powered movement of a mobile trailer. The trailer stand assembly including a leg holder to receive a bottom end of a trailer A-frame. The leg holder being mounted to either side of a base via a bracket. The base including a jack guide extending from a base top end and an internally mounted jack holder. Wherein the jack guide and jack holder receive a jack member therein to form a fulcrum to allow a user to lift and drop the trailer A-frame. The reversible feet assembly including reversible feet that include a rubberized portion and an oppositely arranged cleated portion. The reversible feet are mounted to an underside of the base so the trailer may be walked with the actuation of the jack member.
