A vehicle has at least two axles, each having at least one wheel for lifting, transporting, and lowering load carriers. A first axle is mounted in a chassis. Lifting elements are provided for lifting and lowering the load carriers. The distance of the second axle relative to the first axle can be changed in the horizontal longitudinal vehicle direction, and the lifting elements are lifted or lowered by a change in the distance of the second axle from the first axle. The at least one wheel of the first axle can be driven by a drive motor that is arranged on the chassis, and at least one lifting element is displaced horizontally inward or outward by the change in the distance of the second axle from the first axle in the transverse vehicle direction.

The present invention is directed to a trailer vehicle apparatus comprising a trailer body, an axle, and a truss suspension structure (TSS). The axle comprises a shaft traversing the trailer body width. TSS comprises first and second platforms and truss structures. The first and second platforms comprising a first and second proximate end, respectively. Each truss structure is: perpendicularly oriented relative to the top surface of the platforms; affixed to corner nodes of the first and second proximate ends; and comprises a strut channel perpendicularly oriented relative to the top surfaces of the platforms as well as traverses a length of the truss structure. TSS is affixed to a bottom surface of the trailer body. The axle shaft comprises strut structures each slidably mounted within a strut channel. Strut structures are configured to traverse the strut channel as the trailer vehicle converts between a mobile state and a stationary state.

A hydraulic drop frame trailer for a tow vehicle, the hydraulic drop frame trailer including a trailer frame having two sides and a hitch, a pair of wheels, a first and second frame bracket, a trailer bed mounted over the trailer frame, a first and second pivoting hydraulic cylinder, a plurality of hydraulic hoses, a first and second pivoting arm, an operating station connected to a power supply, a first and second axle-less wheel mount with independent suspension mechanism mounted to the first and second pivoting arm, and a plurality of safety locks, each securing an arm to the trailer frame for locking each rotating arm to the trailer bed during transport.

The application discloses a Drop Deck Trailer having a pivoting axle system that allows the deck of the trailer to be incrementally lowered to the ground. When coupled to a tow vehicle, the partially lowered deck becomes a ramp to load and unload a vehicle. The unloaded trailer can be backed into a standard garage, uncoupled, and lowered completely to the ground. The UTV or light vehicle can then be front-loaded on the trailer. This capability allows the convenience and cost savings of simultaneously storing a UTV or other light vehicle in the same standard garage space. A unique articulated tongue assembly allows the operator to minimize the footprint of the parked trailer, allowing smaller spaces to be used for storage or simply eliminate a trip hazard. The Drop Deck Trailer is a combination of innovative features that provides convenience and cost savings.

A trailer has a main frame with a neck portion on its forward end. A pivot fifth wheel is rotatably affixed to the forward end of the neck portion. The pivot fifth wheel releasably attaches to the fifth wheel of a towing vehicle. An axle frame is rotatably affixed to the rearward end of the main frame, and rotates with respect to the main frame. The pivot fifth wheel and the axle frame are configured to pivot and move the main frame upwardly a vertical distance.

Systems and methods for loading a container onto a container carrier comprising, lowering a set of rails of the container carrier from a raised position to a lowered position, wherein a horizontal surface of each of the set of rails is lower than the bottom surface of the container, expanding, horizontally, the set of rails, to an expanded position, moving at least one of the container carrier or the container so that the container is between the set of rails, contracting, horizontally, the set of rails, to a contracted position, such that the horizontal surface of each of the set of rails is directly underneath the bottom surface of the container and raising the set of rails from the lowered position to the raised position, such that the horizontal surface of each of the set of rails lift the container off the supports.

A trailer for transporting a crop harvester header, such as a forage harvester header, after it has been separated from a transport vehicle such as a self-propelled crop harvester. The trailer includes an elongated frame having forward and rearward ends. A first wheel assembly is mounted at the forward end of the frame and a rear wheel assembly is mounted at the rearward end of the frame. The forward end of the elongated frame is hingedly secured to the front wheel assembly so as to be selectively movable between an upper transport position to a lower loading position. The rearward end of the elongated frame is hingedly secured to the rear wheel assembly so as to be selectively movable between an upper transport position to a lower loading position.

Aspects of the disclosure relate to a trailer having a frame suitable for transporting an item, such as an oil drilling pipe. The trailer includes a plurality of stabilizers for supporting the frame over a surface, at least one axle attached to a plurality of wheels. The trailer further includes an axle pin group includes first and second axle pins interconnected to respective hydraulic cylinders. The trailer further includes leaf springs connected to respective sides of the frame and mounted to the axle. Retraction of the axle pins away from the leaf springs enables movement of the frame with respect to the axle due to the weight of the frame, if the stabilizers are retracted. In this configuration, the frame can be raised and lowered with respect to the surface. Methods of use are also disclosed.

A combine header transport device includes a header support member. A frame is in mechanical communication with the header support member. The frame includes a first frame member and a second frame member. The frame members are in a parallel relationship with each other. A first pair of wheel assemblies are rotatably connected to a first axle assembly. The first axle assembly is attached to the frame adjacent a first end thereof. A connector assembly is attached to the frame adjacent a second end thereof. The connector assembly provides an axis about which the combine header transport device is rotatable. The connector assembly includes a first connector and is configured so that a position of the first connector is adjustable in a vertical direction.

A trailer designed to be lowered and raised in shallow water to launch a boat or any other type of watercraft. The lowering and raising of the entire trailer is accomplished by (1) the front end of the trailer transforming the tongue and extension of tongue from a substantially straight alignment to a bent alignment by hingedly rotating the extension of tongue in relation to the tongue as facilitated through the use of a first elongated lever or rod and gravity, (2) the rear or back end of the trailer providing a rotation of an extension about the wheel hub to the wheel using a tube surrounding a rear axle that is actuated through the use of a second elongated lever or rod, and (3) all of this being accomplished at the same time from the interaction of the first elongated lever or rod and the second elongated lever or rod through a second arm located at a transitioning hub.
