A semi-trailer is provided, including a wheeled chassis having at least one wheeled axle at a rearward end and a retractable support at a forward end, a body comprising a cargo deck and an underride guard assembly that is movable in response to an upward force applied thereto.

An apparatus for transporting a helicopter by ground transportation is hereby presented, the apparatus comprising a mechanism pulling on the rotor assembly to alleviate at least a portion of a mass of the blades to prevent mechanical compression to be applied on a rotor of the helicopter when the helicopter is transported with the apparatus. A trailer thereof, an operation command center, a helicopter crate and a method of use thereof are also presented therein.

A trailer neck reinforcement structure includes a first beam reinforcement structure that includes: (i) a first beam inner insert connected to an inner side of the first beam; and, (ii) and a first beam outer insert connected to an outer side of the first beam. A second beam reinforcement structure includes: (i) a second beam inner insert connected to an inner side of the second beam; and, (ii) and a second beam outer insert connected to an outer side of the second beam. Internal cross members extend between the first beam inner insert and the second beam inner insert. A first group of external cross members are located between the first beam outer insert and the left side rail, and a second group of external cross members are located between the second beam outer insert and the right side rail. Each external cross member comprises an inner segment connected to an outer segment.

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 method of manufacturing a cylindrical cargo container includes: providing a plurality of rigid panels together formable into a cylindrical shell; forming a first semi-cylindrical shell from a first set of the panels; forming a second semi-cylindrical shell from a second set of the panels; forming the cylindrical shell from the first semi-cylindrical shell and the second semi-cylindrical shell; forming a collar conformably encircling the cylindrical shell; constricting the collar to compress joints formed at abutting edges of pairs of adjacent panels; rolling the cylindrical shell and collar to bring respective joints of pairs of panels to a lower position, and welding an inside seam of the joint when at the lower position; removing the collar from the cylindrical shell; and rolling the cylindrical shell to bring respective joints of pairs of panels to an upper position, and welding an outside of the joint when at the upper position.

An event vehicle dispatch device includes: an event notifier configured to notify a plurality of vehicles or owners of the vehicles of an event held in an area in which the plurality of vehicles are able to park; and an adjuster configured to adjust the number of vehicles corresponding to vehicle attributes of vehicles arriving at the area based on the vehicle attribute of each of the plurality of vehicles.

Lift frames for a vehicle in this disclosure may include a frame body on a top portion of a frame, the frame body extending from a first end to a second end; a lift mechanism moveable with respect to the first end of the frame body, the lift mechanism comprising: a lift body having a first end and a second end, a lifting surface on the first end of the lift body and the second end of the lift body being positioned so as to be movable with respect to the first end of the frame body, wherein the lifting surface is positioned to engage an underside of a cargo container when placed on an upper side of the frame body; and an inflatable air bag having an upper side and a lower side and mounted on the lower side to a platform positioned on the frame beneath the lift body, wherein the inflatable air bag is connected on the upper side thereof to a mounting surface attached to the lift body; and a source of compressed air in fluid communication with the inflatable air bag. Such lift frames may include one or more such lift mechanisms associated with the compressed air source and the lift frames may be used to load and unload cargo containers locked and supported by the lift frames in transit and unlocked and detached from the lift frames when delivered in an easy and safe manner.

Systems, methods, and apparatuses for engaging, lifting, and moving objects such as wheeled cargo trailers are provided. In one embodiment, a mobile apparatus includes a transport mechanism, a frame, and one or more lift assemblies. The lift assemblies may be adjusted using one or more attached actuators that position the lift assemblies and/or components thereof for engaging and lifting an object. The transport mechanism may be autonomously operated. A vision system may be used to locate and identify objects and/or guide the mobile apparatus into position to engage and lift the objects. An adapter for a pneumatic braking system of a wheeled cargo trailer is also provided. The adapter provides a pneumatic attachment for a pressurized air source that is separate from a glad hands connector attached to the braking system.
