A mechanical utility invention that creates a self-leveling detachable base that when attached to the member beam of the parent application U.S. Ser. No. 15,703,993, creates utility in its substantially different shape, mobility, multi-functional capabilities, and sustainability from its conventional counter part. It can be utilized as a means for independent balance, manipulate angular degrees, attaching to a sub-surface, and attaching to additional member beams. Additionally, it can be used with the expandable sustainable platform from the parent application. Additional utilities include, but not limited to: creating an arch way, creating a plumb and post without the use of digging and concrete, creating a means for a work to attach a beam without the need to for additional workers to stabilize during attachment. Thereafter, it can be used lend to a member beam the ability to install and uninstall and used again for like or different utilities, making the base and the beam largely sustainable.

An extendable and retractable column which is formed from at least three linked sections or chains. The linked sections include a plurality of individual segments linked end to end. As the linked segments are extended, each of the individual segments of the linked chains engage individual segments of adjacent linked sections to form a column. As the linked sections are retracted, each of the individual segments of the linked sections disengage from the individual segment of the adjacent linked sections and the individual linked sections may be rolled up into a multi-sided form for compact storage.

A wind turbine tower configured to support a wind turbine nacelle and a rotor, and with a tower wall of an inner surface and an outer surface. The tower is tethered by a number of cables, each cable extending between a first end anchored to an anchoring element and an opposite, second end attached to the tower at an attachment element. Two cables extending from two different anchoring elements are attached to the tower such that longitudinal projection lines from the second ends of the two cables converge at a convergence point, which lies at a location at a certain height and inside the tower wall thickness. Alternatively, the convergence point lies inside the tower within a distance of three wall thicknesses from the wall inner surface as measured at the height and in a direction perpendicular to the central longitudinal axis of the tower. The invention further relates to a method of erecting a wind turbine tower tethered by cables and configured for supporting a rotor assembly, and wherein the tower comprises a number of tower sections joined to each other. The method comprises positioning a first tower section, attaching at least some of the tethering cables to a second tower section while the second tower section is on the ground, lifting the second tower section with the attached cables onto the first tower section, and joining the second tower section to the first.

A mechanism for lowering a pole, such as a light pole, is disclosed. The mechanism includes a base arranged to rotate about a vertical axis of a pole portion, and an engaging portion arranged to rotate about an operating axis. The operating axis is in the order of 115 relative to the vertical axis. A pole member is fixed to an arm of the engaging portion.

The present invention relates to an assembly for rotating a suspended load around a substantially vertical axis, the assembly comprising an inner rim configured to have a fixed relationship with the suspended load to be rotated, an outer rim engaging the inner rim in a manner so that the inner and outer rims are configured to perform rotational movements relative to each other during rotation of the suspended load, and a drive unit for performing the relative rotational movement between the inner and outer rims. The assembly of the present invention may be secured to a lifting yoke for lifting wind turbine related components, such as entire wind turbine towers, wind turbine tower sections, nacelles, rotor blades or containers.

Described is an auxiliary device for realizing a bolt connection between connecting flanges, placed against each other, of a first and a second structure. The auxiliary device includes a support body provided with a number of receiving positions for a bolt. The receiving positions are aligned with corresponding bolt holes in the connecting flanges to be placed against each other. The auxiliary device further includes a moving mechanism with which the support body can be moved toward the connecting flanges which are arranged against each other so that a number of bolts arranged in the receiving positions are arranged substantially simultaneously through the bolt holes. Also described is a corresponding method.
