A wall component and other components for a building structure wherein the wall component has a spanning beam spanning the length of the wall component, one or more structural column assemblies positioned between the spanning beam and a floor plate which are structured to carry structural weights and loads received from the spanning beam. The structural column assemblies are separated by a longitudinal distance so as to define an intercolumnar region which is greater than a width of a member selected from the group consisting of a door assembly and a window assembly, and there is an exterior panel fastened between the first and second structural column assemblies that defines a generally continuous and uninterrupted planar surface over the intercolumnar region.

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 split chassis system includes a first chassis base portion that is configured to house a first component and a second chassis base portion that is configured to house a second component. The second chassis base portion is positioned adjacent the first chassis base portion such that a first chassis coupling member included on the first chassis base portion is coupled to a second chassis coupling member included on the second chassis base portion. The split chassis system further includes a leveling subsystem that is coupled to the first chassis base portion and the second chassis base portion. The leveling subsystem aligns the first chassis base portion and the second chassis base portion such that the first chassis base portion and the second chassis base portion substantially maintain coplanarity when the first chassis coupling member is coupled to the second chassis coupling member.

A simple and lightweight solution that provides shippers of dry bulk material an apparatus that facilitates the efficiencies of backhaul pricing in the form of a trailer that is convertible from a configuration used with dry bulk material in an efficient manner (i.e., sealed to outside exposure, food safe, easily cleaned, etc.) to a configuration used with packaged goods as efficiently as a standard van trailer (i.e., must allow forklifts to load palletized and packaged goods for conventional loading and unloading at conventional warehouses with conventional loading docks).

A wall component and other components for a building structure wherein the wall component has a spanning beam spanning the length of the wall component, one or more structural column assemblies positioned between the spanning beam and a floor plate which are structured to carry structural weights and loads received from the spanning beam.

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 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 trailer for transporting a container has a frame mountable to a vehicle. The frame has a rear frame section mountable above a rear wheel assembly of the trailer, and a front frame section connected to and disposed forward of the rear frame section in a forward direction of travel of the vehicle. The front frame section has a king pin mountable to a hitch of the vehicle and a forward-most end. The forward-most end is moveable relative to the kingpin in a direction parallel to the forward direction of travel to extend and shorten a length of the front frame section between a fully-lengthened configuration and a fully-shortened configuration.

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.
