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 mobile generator includes a housing having a top portion, a first side portion, and a second side portion, wherein the first side portion includes an energy-receiving component. The mobile generator also includes an arm pivotally coupled to the housing at a first pivot point and to the first side portion at a second pivot point. A first motion controller is configured to drive rotation of the arm about the first pivot point, and a second motion controller configured to drive rotation of the first side portion about the second pivot point.

A safety trailer is shown including first and second platforms, at least one of said first and second platforms having an axle and wheels attached thereto; a plurality of interconnected wall sections positioned between and connected to the first and second platforms, the plurality of wall sections defining a protected work area on a side of the trailer; and wherein the trailer supports a ballast member, the ballast member being positioned near a first side of the trailer and the wall sections near a second, opposing side of the trailer, the ballast member offsetting, at least partially, a weight of the plurality of wall sections.

The present invention contemplates an apparatus for, and methods of, conveniently transporting cargo by holding cargo securely in a way using a transport apparatus that can be coupled to a vehicle, for easy and convenient transport of the cargo. The invention contemplates a transport apparatus that is capable of horizontal, vertical, telescoping, and/or rotational collapse and/or expansion. The invention contemplates wheels on a collapsed transport apparatus that make moving from place to place very convenient, whether the transport apparatus is expanded or collapsed. Embodiments can be used to secure and transport cargo such as bicycles. Embodiments of the invention allow coupling of a transport apparatus to a vehicle by use of a standard ball joint and/or trailer hitch. Other embodiments could comprise a trailer connection attachment, which can be used to couple a transport apparatus to a vehicle in cases where the vehicle lacks its own trailer hitch.

A foldable transportation trailer able to be folded in two separate locations to enable the folded trailer to assume a vertical position behind the vehicle towing it, when not in use, thus providing a substantially minimal footprint to the trailer in its compacted state. In this manner, when compacted and folded, the trailer reduces from an elongated length of approximately 20 feet, to a length of 3 feet when compacted.

A trailer carrying a utility pole has parallel spaced beams and transverse interconnections at a front and spaced inward from a rear of the beams. Rests on top of the interconnections support a pole-holding channel that is connected to the beams with plural pivoted frames. A wire passes through turning blocks at a rearward end of the channel and near the rearward interconnection, rotating the frames and pulling the channel towards the rearmost transverse interconnection until the channel holds the pole upright. The trailer is lowered and the pole is connected to a prepared supporting block. The channel is detached from the pole. The channel and frames are lowered by releasing the wire, and the trailer is raised and towed away.

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 trailer is provided for having a self-propelled swather mounted thereon. The trailer includes first and second caster wheel supports and first and second drive wheel supports. The caster wheel supports are selectively movable being stowed and support positions. The drive wheel supports are selectively movable between horizontally disposed and vertically disposed positions. Each of the caster wheel supports includes a caster wheel turning assembly to partially pivot the associated caster wheel as the swather is backed onto the trailer. The trailer also includes extenders for attachment to first and second ramps. The extenders may be stowed on the bumper.

A material delivery and waste removal trailer that includes a scissors lift mechanism mounted on a main frame of the trailer that elevates a storage bin from the main frame and retracts the storage bin to the main frame. The storage bin has a frame mounted on the scissors lift and a container mounted to the frame of the storage bin. The container of the storage bin is movable pivotally vertically away the frame of the storage bin and linearly horizontally through the frame of the storage bin. A first hydraulic cylinder controls movement of the scissors lift mechanism away from the main frame and toward the main frame and a second hydraulic cylinder controls movement of the container of the storage bin away from the frame of the storage bin and toward and the frame of the storage bin.

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.
