The mobile retail store structure of this disclosure fits in a standard-sized parking space, and may be configured with other similar structures to expand the retail area.

In a kit comprising a self-propelled two-track stilt vehicle and a transportation trailer, a lifting device, braced on the trailer, is provided that acts on central elements of the running and carrying structure of the stilt vehicle. The running and carrying structure of the stilt vehicle having four wheels comprises, oriented transversely relative to the travel direction, front and rear transverse structures, on which two stilt structures respectively having a wheel-carrying unit that carries at least one wheel are disposed on both sides at the end. The transverse structures are constructed in multiple parts having a middle piece and left and right end pieces, which can be fixed in various width positions. The stilt structures are constructed in multiple parts having primary parts connected to the associated end piece of the transverse structure and secondary parts, fixable thereon in various height positions and on which associated wheel-carrying units are disposed.

The present invention relates to a transport wagon consisting of a base frame, wherein the base frame comprises a rotatable bogie assembly on its front side for attachment to a powered tow or push truck and comprises one or more front steering wheels placed on the front side of the base frame and one or more rear steering wheels placed on the rear side of the base frame, wherein the one or more front steering wheels and the one or more rear steering wheels are coupled in such a way to the rotatable bogie assembly, that in operation the one or more front steering wheels rotate along with the rotatable bogie assembly and that the one or more rear steering wheels rotate in opposite direction with respect to the rotatable bogie assembly, wherein the base frame comprises at least one longitudinal beam to which a front cross beam, a rear cross beam and at least one intermediate cross beam are arranged with intermediate spaces, wherein at least one intermediate space is arranged for receiving goods, wherein an intermediate wheel suspension with two or more intermediate wheels is arranged under one or more of the intermediate cross beams. The present transport wagon provides a transport wagon that remains well steerable on uneven floors.

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.

Methods of transporting a plurality of freight containers are disclosed, including stacking one or more containers on a transportation vehicle, where one or more of the stacked containers is a vertically collapsible container in a collapsed position, where at least one of the vertically collapsible containers includes: a frame assembly including: a plurality of rectangular frame members; a plurality of articulated vertical frame members disposed between the rectangular frame members; and where the articulated vertical frame members are positioned and arranged to retract to within the frame assembly; a lifting mechanism positioned and arranged to elevate the rectangular frame members from each other; and where the lifting mechanism is disposed between the uppermost rectangular frame member of the frame assembly and the lowermost rectangular frame member of the frame assembly.

A transportable fold-out at least partial enclosure includes in one aspect of the invention a stationary platform having a major surface defining a stationary plane, a plurality of side edges, a front edge and a back edge. A primary platform has a major surface defining a primary plane, an inside edge, an outside edge, a front edge, a back edge, the inside edge being joined to the stationary platform, the primary platform having a folded position in which the primary plane and stationary plane are oblique or orthogonal, and the primary platform having an extended position where the primary platform is unfolded from the stationary platform.
