Aspects of the disclosure relate to a trailer having a frame suitable for transporting an item. The trailer includes a boom which may be raised from the trailer and support cables used to move the pipe from the trailer to a storage or other location. The boom is raised and lowered by a hydraulic system comprising a travel height truss. The travel height truss may comprise two portions, pivotably connected to each other, one portion pivotably connected to the frame and the other pivotably connected to the boom. The travel height truss provides greater leverage than would otherwise be available for the maximum size and weight of the load available for a given (fixed) maximum length of trailer. In this manner, the boom frame can be raised to greater heights, while maintaining horizontal distance, than otherwise. Methods of use are also disclosed.

A dampening system is configured to isolate and dampen vibrations from transferring between a towing vehicle and gooseneck trailer. The system includes a neck support structure, a gooseneck having a coupling, a trailer mounting structure, the trailer mounting structure in communication with the neck support structure based on one or more hinges, a set of air bladders, wherein the air bladders are in communication with the neck support structure and the trailer mounting structure, and a flatbed, wherein the flatbed is in communication with the trailer mounting structure.

A container transport system for transporting an intermodal freight container includes: a tow assembly pivotally coupled to a tow vehicle, the tow assembly including a support frame, a boom assembly mounted on the support frame, the boom assembly having a boom frame and a lifting actuator mounted on the boom frame; a lift beam shaped to attach to an end of the intermodal freight container, the lift beam mechanically associated with the lifting actuator; a dolly removably coupled to one of the tow assembly and tow vehicle, the dolly including a bogey frame including a plurality of wheels attached to the bogey frame, a pair of brackets located on sides of the bogey frame, the brackets spaced apart such that a width of the intermodal freight container fits between the paid of brackets.

A novel method of repairing and modifying a heavy-duty industrial rack includes: a) providing an enclosed trailer having: 1) a forklift compartment; 2) a ramp for the loading and unloading a forklift and its payload to and from the trailer; 3) a forklift for moving a rack to and from the trailer; 4) a rack repair compartment; 5) rack repair raw materials; 6) at least one rack component bonding apparatus for bonding components of the rack; 7) at least one rack component bending apparatus; 8) at least one rack machining apparatus; and 9) a hitch for coupling the trailer to a truck for moving the trailer to a new location when desired; and b) moving the trailer to an onsite location having a rack targeted for repair or modification. The method also at least includes: c) unloading the forklift from the trailer via the ramp; d) driving to the forklift to the targeted rack; e) lifting the targeted rack and transporting it to the trailer; f) loading the targeted rack onto the trailer via the ramp; g) locating the targeted industrial rack in the rack repair compartment; h) performing repairs or modifications on the rack; i) after repairs or modifications, lifting and removing the rack from the trailer via the forklift and the ramp; j) driving the repaired or modified rack to an onsite location; and k) unloading the repaired or modified rack from the forklift. A novel trailer apparatus is separately disclosed.

A transport system can employ a transport assembly with a main support member attached to a mounting connection, a tow connection, a suspension, and a horizontal articulation mechanism. The horizontal articulation mechanism may be configured to raise the suspension of a ground surface along a first direction and move the main support member in a second direction with the first direction being orthogonal to the second direction.

A dump trailer comprising a goose neck adapted for removable coupling to a tractor unit and a dropped frame joined to the goose neck and extending rearwardly of the goose neck. A plurality of trailer wheel and axle assemblies are joined to the bottom of the rear of the dropped frame. Each of the plurality of trailer wheel and axle assemblies has left and right wheels suitable for highway travel. An open bed is joined to the top of the dropped frame for receiving cargo. The open bed extends below the goose neck and has a front and a rear opening for permitting discharge of the cargo from the open bed.

An upper deck frame assembly for a trailer chassis includes a flushed floor section defining a first floor height, and a header section, with a header, forward of the flushed floor section and defining a second floor height above the first floor height. A towing assembly may be secured to the header. A reduced size header section increases usable floor space, and the towing assembly is securable to the header.

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 boom which may be raised from the trailer and support cables used to move the pipe from the trailer to a storage or other location. The boom is raised and lowered by a hydraulic system comprising a primary cylinder and a secondary cylinder, each of which is attached to a lift assist assembly. The lift assist assembly provides greater leverage than would otherwise be available for the maximum size and weight of the load available for a given (fixed) maximum length of trailer. In this manner, the boom can be raised to greater heights, while maintaining horizontal distance, than otherwise. The lift assist assembly may be incorporated into an original manufacture or added in a retrofit application. Methods of use are also disclosed.

A platform trailer includes a neck reinforcement structure located in the neck region to provide for a reduced height in the neck region of the trailer to increase the cargo-carrying capacity of the trailer. The height in the neck region of the trailer is less than 30% of the height in the rest of the trailer. A fifth wheel plate includes a main portion secured to both the first and second beams of the trailer. The fifth wheel plate includes a bifurcated tail portion including a first tail portion connected to the first beam and a second tail portion connected to the second beam. A kingpin is connected to the fifth wheel plate and is adapted to be engaged by an associated tractor fifth wheel.

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.
