At least one and, preferably, a pair of generally parallel side wall assemblies for use in a pick-up truck bed are provided. Each of the assemblies includes a vertically extending side wall having an upper surface and a set of linearly spaced pockets extending from the upper surface and into the side wall. Each of the pockets receives and retains a stake in a stowed position within the side wall wherein the bed has a first storage capacity. Each of the pockets allows its stake to move therein to an extended position above the upper surface wherein the bed has a second storage capacity greater than the first storage capacity in the extended positions of the stakes.

A tailgate enclosure for use with a vehicle can include a plurality of cross-members, a first upright, a second upright, and only one additional upright. Each of the cross-members can be vertically spaced apart from an adjacent one of the cross-members and can include a first beam, a second beam, and a central beam having a first end and a second end, the central beam positioned at least partially between the first and second beams. The first upright can secure the first beam of each of the cross-members to a first sidewall of the vehicle and the second upright can secure the second beam of each of the cross-members to a second sidewall of the vehicle. The additional upright can be positioned along the central beam of each of the cross-members between the first and second ends of the central 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 plurality of stabilizers for supporting the frame over a surface, at least one axle attached to a plurality of wheels. The trailer further includes an axle pin group includes first and second axle pins interconnected to respective hydraulic cylinders. The trailer further includes leaf springs connected to respective sides of the frame and mounted to the axle. Retraction of the axle pins away from the leaf springs enables movement of the frame with respect to the axle due to the weight of the frame, if the stabilizers are retracted. In this configuration, the frame can be raised and lowered with respect to the surface. Methods of use are also disclosed.

A modular gate combined with multiple functions which can be easily employed with existing tailgates without any hardware or mounting modifications to existing truck beds. There is provided a modular tailgate system having a tailgate portion in combination with a plurality of functions. The modular tailgate system integrates any combinations of at least two of the plurality of features without affecting existing body sides and/or existing truck beds. Integrated features include a multi-functional gate (e.g., swing, drop, etc), storage (e.g., normal, sealed, refrigerated, heated, etc), step(s), lighting (e.g., ingress/egress, bed interior, removable, trailer hitch, parking, etc), bed extension(s), power (e.g., 12v and/or 110v), tie downs (e.g., ratchets, anchors, etc), sawhorse, magnet(s), table(s), bench(es), seat(s), net(s), any other predetermined desired function, etc., and combinations thereof.

A monopile fastening system (1, 9, 17) for retaining one or more elongated monopile during sea transport and/or quay transport, the system comprising: —at least two supporting devices (3, 11, 18); —a supporting frame (2, 10, 23) for securing the at least two supporting devices to a surface of a vessel, barge or a sea transport unit, the at least two supporting devices having each at least one surface (6, 32) in contact with a surface (7, 33) of the supporting frame; wherein each of the at least two supporting devices comprises, at least two supporting elements (4, 5, 12, 13, 20, 24, 27), the supporting elements having each at least one surface (14, 15, 25, 26, 28, 29) in contact with each other; wherein the at least two supporting elements are connected with each other through one or more displacing means (16, 22, 30); and wherein the one or more displacing means are means for displacing the at least two supporting elements along the at least one surface in contact with each other.

A system and method are used for transporting a plurality of tower sections of a wind turbine on beds of transport devices, such as flat railcars. Supports affix at support locations on beds to accommodate at least one of the tower sections on each of the transport devices. The supports can include bed supports, such as tabs, extending from the beds, and can include cradle supports with slots that engage on the tabs. A circumferential dimension of a cradle is adjusted on each of the supports against which the tower section rests. Each of the tower sections is then supported with at least two of the supports by loading the tower sections on the transport devices. An end of each of the tower sections is then affixed to a flange on at least one of the supports on each of the transport devices.
