An extendable trailer including a nose end for selectively securing the extendable trailer to a vehicle wherein the nose end includes an extendable frame portion. The extendable trailer also includes a tail end having a primary frame to support objects to be transported on the extendable trailer and a central tube member supported by the primary frame. The central tube member includes an inside portion. The extendable trailer further includes a telescopic tube member of the nose end that slidably engages the central tube member. The extendable trailer also includes a centralizer disposed on an insertion end of the telescopic tube member that engages with the inside portion of the central tube member to help centrally position the telescopic tube member in the central tube member when the telescopic tube member is extended into and out of the central tube member. A method of transporting objects using the extendable trailer. The method includes determining a desired length of the extendable trailer and positioning the telescopic tube member relative to the central tube member to achieve the desired length. The method also includes transporting objects on the extendable trailer.

A trailer having a deck and a flip-over ramp. The deck and one side of the flip-over ramp are convertible from a flat position to a position with cradles that are configured to hold one or more round hay bales. The deck may tilt, and side rails may cooperate to form the cradle region. The flip over ramp may also pivot about a horizontal axis to form a pathway from a ground surface to the deck. Side rails may pivot both about a horizontal axis, and about a vertical axis near the flip-over ramp to allow clearance when the ramp is deployed.

A heavy vehicle and machinery trailer having: (i) a trailer base with wheels and suspension; (ii) a trailer bed supported on the trailer base by the suspension; (iii) loading ramps connected to the trailer bed where the suspension, or other methods such as hydraulically operated landing legs, are adapted to allow an operator to alter the pitch and/or roll angle of the trailer bed relative to the ground surface and wherein where the loading ramps are adapted to have varying lengths such that the ramps can be evenly pitched when they are extended to the ground on a sloped surface. The trailer has a hydraulic system under the control of an electrical controller which is operated by a user. The electrical controller has a preset matrix of safe loading and unloading parameters which it uses to determine whether the sensed state of the trailer is safe for loading or unloading.

A spread axle assembly for a trailer has the ability to pivot about itself to achieve a storage configuration that advantageously shortens the overall length of the trailer and reduces tire wear. It also has the ability to extend between a close position in which the rear axle of the trail is proximate to its axle and one or more spread or extended positions for better distribution of a load carried by the trailer.

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 raising and lowering of the frame is effected by a lifting and lowering mechanism connected with the wheel assemblies.

A container carrier (1) comprises an elongate main frame (2). The main frame (2) comprises an articulating lifting apparatus (3). The carrier (1) further comprises a second elongate frame (10) slidably connected to the main frame (2) arranged such that one of the frames is slidably arranged within the other frame in the longitudinal direction. The relative position of the two frames (2, 10) is changeable between a retracted position and an extracted position.

A system for virtually experiencing an aircraft includes a trailer, an aircraft fuselage, a cabin module, a head mounted display, and a controller. The aircraft fuselage is disposed in the trailer and defines an interior with a first portion and a second portion. The first portion is substantially unfurnished. The cabin module is disposed in the second portion and includes furnishings. The head mounted display is configured for movement within the interior. The controller is configured for generating a virtual aircraft interior based on a position and an orientation of the head mounted display relative to the interior of the aircraft fuselage and for controlling the head mounted display to display the virtual aircraft interior.

A slide-out undercarriage mounted on an underside of a first trailer pulled by a highway tractor. The slide-out undercarriage is adapted for attaching a rear of the first trailer to a front of a second trailer. The slide-out undercarriage includes a fixed undercarriage frame mounted on an underside of a first trailer. A front axle with front wheels is mounted on a front axle frame and a rear axle with rear wheels is mounted on a rear axle frame. The rear axle frame includes a fifth wheel adapted for engaging a king pin on the front of the second trailer. A pair of first slide out tubes are attached to the front axle frame. A pair of second slide out tubes are attached to the rear axle frame. The first and second slide out tubes provide for allowing an operator of the first trailer to adjust the front and rear axles in various load positions under the first trailer when pulling the second trailer.

A trailer moveable by a cab includes: a first section including a cavity and a second section at least partially positioned within the cavity, where the second section is longitudinally movable relative to the first section, such that a length of the trailer is variable. The second section includes a cart including at least one wheel configured to roll along a floor of the cavity and a height-variable member co-acting with the at least one wheel. The second section is configured to move longitudinally relative to the first section by the cart rolling along the floor of the cavity. A towing system and a method for adjusting a length of a trailer moveable by a cab are also disclosed.

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 raising and lowering of the frame is effected by a lifting and lowering mechanism connected with the wheel assemblies.
