A post sleeve installation system can include a plurality of post sleeve installation devices and at least one spacing beam or mechanism. The spacing beam or mechanism can include end portions that rotate about multiple independent axes and can be coupled to a pair of post sleeve installation devices to determine or control the relative locations and orientations between two post sleeves. The post sleeve installation system can be used to install post sleeves for posts for a fence, a rail or other structure supported by posts.

An offshore wind turbine generator comprises a tower 1 and a platform 2. The tower 1 is provided with a side door 4 accessed from the platform 2 using a stairway 5 leading to an upper platform 6. The upper platform 6 is formed from the upper surface of a cabinet 7 which houses a diesel backup generator. Both the backup generator and the cabinet 7 are mounted to the tower 1 by bolts, such that the cabinet and backup generator are fully supported by the tower 1. A diesel fuel tank 12 is also mounted to the tower 1 by bolts. The fuel tank supplies diesel fuel to the backup generator.

A mechanical utility invention that creates an expandable sustainable member beam with spikes with utility in its substantially different shape, mobility, multi-functional capabilities, and sustainability from its conventional counter part. It can be utilized independently, as a utility stand, in plurality, sharing a base(s) and platform(s), as a step, or in conjunction with other expandable sustainable member beams with spikes from which to build. Some embodiments may replace a conventional wood or metal 248 stud in many applications. Additional utilities include, but not limited to: a post, concrete form, assistive device for mobility challenged individuals, independent balance, self-leveling, varying angular degree manipulation, elevational deployment and retraction capabilities. It can be substantially shortened for transport and deploy to varying longitudinal values to regain its utility upon user demand. Thereafter, it can be uninstalled and used again for like or different utilities, making it largely sustainable.

A mechanical utility invention that creates a permanent or temporary rigidity key and fastener designed to be used with the member beam of the parent application, U.S. Ser. No. 15/703,993. It has substantially more utilities than its conventional counterparts: slide bars, chicken feet, u-channel clasps with wing nuts, sashes, and spring and buttons; in that it is different in shape, has multi-functional capabilities, can be used where variable prohibition is desired, consists of only one part, and it can be used as a temporary key or a permanent key. It enlists gravity and compression from the passing segment, thus requiring less pressure from the user than its conventional spring and button counterparts. Making it a superior choice when economy of force is necessary or desired.

A tower assembly for a wind turbine includes a tower and a freestanding internal tower structure assembly. The tower has a tower wall defining an inner surface and an outer surface separated by a tower wall thickness, with the inner surface defining a tower interior. The internal tower structure assembly is positioned within the tower interior. The tower structure assembly includes a plurality of stackable support structures configured to support one or more internal tower components. Further, the tower structure assembly is freestanding within the tower interior.
