A configurable trailer system which includes a chassis supported by one or more axles and any combination of an enclosed trailer, a camper, a livestock trailer, a dump bed and an open-sided trailer. The chassis includes a support surface and, at corners of the support surface, a plurality of locks. Each of the enclosed trailer, camper, livestock trailer, dump bed and open-sided trailer includes a plurality of corner castings configured to selectively and securely couple with the locks. A method for configuring the trailer system includes placing a first one of an enclosed trailer, a camper, a livestock trailer, a dump bed and an open-sided trailer on the chassis and locking to the chassis by engaging the locks with corner castings provided to corners of the first one of the enclosed trailer, camper, livestock trailer, dump bed and open-sided trailer.

Provided herein is a split variable extension width self-propelled motorized transporter (SPMT) vehicle including a widening adaptor that allows for variable spacing of split SPMT trailers thus increasing the width of the loading platform without the need to add more SPMTs and Power Pack Units (PPUs).

A retractable wheel assembly includes arm assemblies, wheels, a retraction arm, and a threaded shaft. The arm assemblies are hingedly attached to a lower frame of a utility vehicle. Each arm assembly comprises a first arm, a second arm, and a third arm hingedly linked there between. Each wheel is connected to the third arm of each arm assembly. The retraction arm is connected to the second arm, and a threaded shaft. The threaded shaft is configured to be actuated rearwardly where the retraction arm is rearwardly pulled causing the second arm to unfold the arm assembly outwardly and deploy the wheels and for motion of the utility vehicle. Then, the threaded shaft is configured to be actuated forwardly where the retraction arm is pushed forward causing the second arm to fold the arm assembly inwardly and fold the wheels and when the utility vehicle is positioned at rest.

A luggage device for a vehicle includes a container including a door that is openable and closable, a first mounting portion facing the door, and a second mounting portion configured to connect the door to the first mounting portion, the container having a fillable space formed therein, and a drive mechanism configured to connect the container to a mount subject such that the first mounting portion or the second mounting portion is attached to the mount subject and to switch mount directions of the container.

A trailer frame including an axle section having two spaced longitudinal frame members connected by at least one cross member, the longitudinal frame members each having a first end and a second end; a rear section attachable to the axle section; and a dimple assemble joining the axle section to the rear section, the dimple assembly including a dimple pattern formed on each frame member of the axle assembly, the dimple pattern on the axle assembly defining a first dimple axis, and a dimple pattern formed on one end of the rear section and nestable within the dimple pattern formed on the axle section, the dimple pattern on the rear section defining a second dimple axis offset relative to the first dimple axis to create a camber between the axle section and the rear section when the first dimple is nested within the second dimple pattern.

A portable towing system for a motorcycle or similar vehicle, such as a trike, the frame of which can be lowered to ground level to facilitate loading of the motorcycle or similar vehicle by pushing or riding the vehicle onto the frame without risk of the vehicle falling off the sides of a steeply inclined ramp. The towing system may be assembled, raised, lowered, and disassembled by a single person, if desired. The towing system also comprises a cargo box to store the frame when disassembled. The raising and lowering of the frame is effected by a lifting and lowering mechanism connected with the wheel assemblies, and at least three heights of the frame are achieved by rotation of the lifting and lowering mechanism of the wheel assemblies. The cargo box and the frame can use the wheel assemblies interchangeably.

A method of assembling a drilling rig may include aligning a trailer with a drilling rig support structure, the trailer carrying a mast and the drilling rig support structure including a step-down substructure. A first end of the mast may be positioned over the drilling rig support structure and arms may be extended from the mast to the drilling rig support structure so that the drilling rig support structure supports the first end of the mast. The mast may translate along a length of the drilling rig support structure. The mast may be coupled to the drilling rig support structure.

An expandable vehicle comprising a vehicle chassis and an expandable structure that is fixed to, carried by, and supported by the vehicle chassis. The expandable structure is expanded when the expandable vehicle is stationary for the stationary purpose of the expandable vehicle and is contracted when the expandable vehicle is being moved. The expandable structure comprises an expandable frame and an expandable body. The expandable body is fixed to, carried by, and supported by the expandable frame while the expandable frame is fixed to, carried by, and supported by the vehicle chassis. As the expandable frame is expanded and contracted, the expandable body is correspondingly expanded and contracted.

The disclosure presented herein relates to a trailer of a collapsible configuration. The trailer comprises a connector connectable to a vehicle. The trailer further comprises a frame structure coupled to the connector. The frame structure comprises a telescopic spine member, a pair of front members pivotally connected to the telescopic spine member and extending from the the telescopic spine member, a pair of lateral members pivotally connected to the pair of front members, a plurality of support members pivotally connected to and extending from the telescopic spine member and connected to the pair of lateral members. The pair of front members, the pair of lateral members, and the plurality of support members are pivotally coupled to the telescopic spine member, thereby providing a collapsible configuration to the trailer. This allows the maneuvering of the trailer in confined spaces.

An interchangeable platform that encompasses side beams at the sides and at least one support structure, with what the side beams are fastened to each other. Side beams are into sideways direction, perpendicular to the longitudinal direction, at least partially open and closed from up and down and they have an upside-down G-profile. An interchangeable platform encompasses at least one longitudinal guide. The interchangeable platform can be guided by the guide to the transport device, can be locked by side beams to the transport device and load fastening equipment can be fastened to side beams. Additionally a transport device that encompasses side guides.
