A method of unloading a structure including a plurality of linear actuators includes extending the plurality of linear actuators to support the structure on the plurality of linear actuators at a first location, retracting the plurality of linear actuators to lower the structure onto one or more crawlers, and sending instructions to the one or more crawlers, receipt of the instructions causing the one or more crawlers to travel across a first surface to carry the structure from the first location to a second location.

An alignment system, a trailer frame alignment system and a method of aligning a trailer frame upon a foundation, the system including a foundation having at least three contiguous vertical walls, a trailer frame guide system including a pair of opposing guides on corresponding opposing walls of the at least three contiguous vertical walls, and a stop guide on the other of the at least three vertical walls between the corresponding opposing walls. The pair of opposing guides on the corresponding opposing walls include a tapered portion having a first distance defined between the pair of opposing guides at distal ends of the pair of opposing guides from the stop guide, the first distance being greater than a second distance defined between the pair of opposing guides between the distal ends of the pair of opposing guides and the stop guide.

A structure includes a first space defined by a plurality of walls and a floor assembly supporting the plurality of walls. The floor assembly includes a frame comprising a plurality of floor joists, at least one upper plate coupled to a top of the frame, and a skid plate coupled to a bottom of the frame, the skid plate comprising a circular opening. The floor assembly further includes a pin socket comprising a cylindrical pipe section positioned around the circular opening, the pin socket configured to receive a rotation pin within the cylindrical pipe section and configured to cause the rotation of the structure about the rotation pin when a lateral force is applied to the structure. The structure is configured to rest on the skid plate during the rotation.

A robotic casting machine (RCM) provides for on-site, or near-site casting and automated production of cast components, such as concrete modular, volumetric building components. The RCM includes stationary and mobile support structures, which can be positioned in a loading configuration, a casting configuration and an ejection configuration in which the cast volumetric component may be ejected from the mold. Tipping machines located beneath the cast component facilitate ejection, rotation and loading of the ejected module onto a transport surface for transport of the module. The support structures are constructed of prefabricated frames that may include at least one standardized section, which may be utilized on every project, and may also include a customized section, which may be provided to achieve desired dimensions of the cast module on a particular project. A casting process is provided in which a volumetric module is cast in a rotated orientation, in which the floor is cast with an initial vertical orientation, the transverse walls extend in a horizontal orientation, which is cast in vertical wall forms, and a longitudinal wall extends horizontally along the top of the mold. Modular, volumetric components created using the RCM and casting process are also described.

A trailer configured to transport a load includes a bed including an upper surface configured to support the load, a first rotation pin configured to move along a slot in the bed, a second rotation pin coupled to the bed, and a winch assembly positioned in the slot and coupled to the first rotation pin by a first rope. The winch assembly is configured to pull the first rotation pin toward the second rotation pin.
