US Patent 11781310 Modular home delivery system

A method of unloading a modular home from a trailer includes extending a plurality of linear actuators coupled to overhanging portions of a modular home positioned on a bed of a trailer until the linear actuators lift the modular home off of the trailer, sending instructions to one or more crawlers to move under the modular home, retracting the linear actuators to lower the modular home such that a lower surface of the modular home rests on a platform positioned on each of the crawlers, sending instructions to the crawlers to move the modular home to an installation location, extending the linear actuators until the linear actuators lift the modular home off of the crawlers, sending instructions to the crawlers to move out from under the modular home, and retracting the linear actuators to lower the modular home to an installed height.
