The present invention relates to a motor vehicle trailer with at least one rigid axle with at least one tubular element. The motor vehicle trailer is characterized in that the tubular element has a yield strength Rp0.2 of at least 600 MPa, a tensile strength Rm of at least 850 MPa, a breaking elongation A5 of at least 14% and the tubular element (10) consists of an air-hardening, mainly bainitic material. In addition, a chassis axle as well as the use of a material for a chassis axle is disclosed.

The present invention relates generally to the field of trailers. More specifically, the present invention relates to a paddleboard trailer device that is comprised of a top surface further comprised of at least one board receiving structure, at least one cooler box, at least one main storage box, and a rear surface with at least one internal compartment. The base of the device further preferably resembles a utility trailer and is durable and rigid such that it can support the weight of multiple paddleboards or surfboards and other heavy objects. The device is also comprised of a board receiving structure that securely and efficiently organizes the boards to prevent damage and enhance accessibility. In this manner, the device can be attached to any vehicle with a trailer hitch, such that a large group of people can easily travel to a water location in a minimal number of vehicles.

A trailer chassis includes a first frame beam, a second frame beam parallel to and spaced from the first frame beam, and a plurality of cross members connected between the first frame beam and the second frame beam. A storage compartment for a folding table or the like is cooperable with the first and second frame beams.

A pneumatic tank trailer includes a carriage and a tank supported on the trailer that can selectively discharge fluidizable material through hoppers of the tank. A nose portion of the trailer has a generally conical shape. The nose portion has a top that slopes downward and sides that taper inward as it extends forward. A cross-sectional center point of a front end of the nose portion is lower than a cross-sectional center point of a rear end of the nose portion along the height of the trailer. The length of the nose portion is at least 15% of the length of the trailer. Adjacent hoppers intersect at hopper crotches. The hopper crotches have short heights and the hoppers are arranged relatively close together.

A trailer includes a housing including an internal frame and an external frame. The external frame is coupled to the internal frame. In certain embodiments, the internal frame is positioned between interior panels and exterior panels of the housing. In certain embodiments, the external frame is spaced from exterior panels.

A trailer having a liftable first axle and an air suspended second axle includes a controller, a first valve coupled to the first axle and a second valve coupled to the second axle. The controller receives an air suspension exhaust request signal and a pressure signal from an air suspension bellows coupled to the second axle. The controller transmits an air suspension control signal to the second valve in response to the air suspension exhaust request signal and transmits a lift axle control signal to the first valve to lower the first axle in response to the pressure signal being less than a predetermined pressure value.

Upright receiver assemblies for attaching to trailers and acting as hitches are disclosed herein. The upright receiver assemblies include (a) an upright and (b) a base, both pieces being releasably attachable to each other. The upright contains a vertical post have a top positioned receiver while the base includes a center plate, two cross bars, and two angled side plates.
