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 jack assembly for mounting on the hitch arm of a wheeled implement frame supports the wheeled frame relative to a ground surface upon which the wheeled frame is engaged. A jack frame of the assembly is fixedly mounted onto the implement frame and pivotally supports a leg for movement between a raised transport position and a lowered position to support the implement frame elevated above the ground when stationary. A first catch on a retainer member pivotal on the jack frame cooperates with a second catch on a link member pivotal on the leg. A linear actuator coupled between the jack frame and the link member acts to both (i) release the catches and extend the leg towards the lowered position, and (ii) engage the catches and raised the leg towards the raised position.

A recreational vehicle includes: an external corner area; and a mounting assembly, including a locking hook plate which is selectively coupled with and decoupled from the external corner area of the recreational vehicle.

Supports utilized to stabilize and/or support parked trailers, such as semitrailers parked at loading docks while loading and/or unloading cargo, are disclosed. Some example embodiments may include jacks mounted to repositionable frames, which may be mounted to posts. Some example embodiments may be configured to engage with king pin plates and/or king pins on the undersides of trailers.

An apparatus and a method for loading a spare tire of a vehicle are provided so that the spare tire does not appear on a bottom of a luggage compartment of the vehicle without interfering with a space or a structure for mounting a battery. The apparatus and the method for loading the spare tire of the vehicle includes: a jack-up device for providing a supporting force to support the spare tire positioned on an upper side thereof in a state of being stored in an accessory storage space of a vehicle body panel; and a support assembly installed in the accessory storage space of the vehicle body panel to support the spare tire loaded thereon.

A Wheeled Cart which can be connected in the same manner as the car's own wheel, allowing, upon removal of the car wheel, the positioning of the Wheeled Cart with the same screws or the same nuts, without needing to make any adaptations; the idea was to develop a device that adapts to the different configurations of wheel fastening on wheel holders, according to how it is designed on the wheel holder, which is why a very important point that is taken into account is that the chassis or main body must regulate the layout or configuration of the holes, as well as the diameter of the wheel to be replaced, the objective is to enable movement of the car when the latter cannot do so with its wheels, which is why the device is designed based on two bodies named chassis facing each other, with a common central connection part, one superior part named superior end and one inferior part named inferior end, which accommodates a 360 directional wheel and a third connecting element between the chassis, which affixes the position of the latter with the purpose of securing it; and the device is characterized by the fact that its Body which we name Chassis is comprised of two parts connected in the central area of each of the parts by means of a bolt bushing, and which we will hereinafter name Central Part, and from this Central Part a formation extends to each part of the chassis, in a symmetrical manner, generating what we shall name Superior Ends and the other Inferior Ends; each of the latter accommodates a wheel with its corresponding fork and 360 pivotal axis; and in turn each Superior End has on its extremities through-holes of a greater dimension than that of the adjustment screws for the wheels of the car and of a lesser dimension than the diameter of the nut of that screw or screw head; in turn, between each of the Superior Ends and the Central Part of each part of the body of the chassis there is a screw with a wing nut fixed to the upper body of the chassis, with a component named bridge located between both screws and affixed by the wing nuts, with a through-hole in its central part of the same diameter as the through-holes at the extremities of each of the Superior Ends and this bridge has an oval orifice instead of a circular orifice in the connection with each screw by means of a wing nut.

An adjustable motor mounting system having an adjustable motor mount and a gear box with a motor. The adjustable motor mount has a first plate attached slidably to I-beams on a frame of a semi-trailer and attached to a second plate with a hinge so that the second plate is rotatable relative to the first plate. A third plate is attached slidably to the second plate and has a mounting plate attached thereto. The gear box is attached to the mounting plate and to a landing gear crankshaft of the semi-trailer. The adjustable motor mounting system renders the gear box movable towards or away from the landing gear crankshaft, movable leftward or rightward of the landing gear crankshaft, and movable upward or downward relative to the landing gear crankshaft.
