A printing system for printing the lower base of a wind tower or the entire wind tower. The system includes a printing device configured to print the coaxial polymeric shells with an empty volume between the shells. The printing device uses the coaxial polymeric shells as driving rails. A concrete material deposition device configured to deposit the concrete material into the empty volume between the polymeric shells, and a rebar handling device is configured to deliver rebars into the volume between the polymeric shells to reinforce the deposited concrete material.

There is disclosed a mobile pole system having a temporary utility pole and a mobile structure. The temporary utility pole has a telescoping mast with at least one bracket coupled thereto to receive wires, cables or an item utility equipment. The telescoping mast is formed by a plurality of segments slidably engaged with each succeeding segment of the plurality of segments. The mobile structure has a plurality of supporting members extendable to stabilize the mobile pole system.

A tower assembly system can include a self-climbing platform that can carry a load to a determined height, which once attained, can place the load into position. A method for assembling a wind turbine can involve placing a first tower section in an upright position on a tower base and using an elevator assembly platform attached to the first tower section to elevate, position and connect subsequent tower sections until the subsequent tower sections are located directly above the first tower section in a vertical tower assembly. The elevator assembly platform can perform vertical displacement operations and lateral displacement operations with respect to one or more components of the wind turbine, such as, for example, the first and subsequent tower sections, nacelle, blades, etc.

In an aspect, the present disclosure describes a method comprising using at least one robot to fully autonomously position and assemble at least one solar module and its supporting structure at a sensed geolocation without aid from a user.

A connecting device for a tower-like structure is provided, and includes a plurality of connecting elements which are arranged between an upper component and a lower component of the structure in order to produce a slip joint, and for the purpose of load transfer between the upper component of the structure and the lower component of the structure, are to be positioned next to one another in the peripheral direction about the longitudinal axis and/or in the longitudinal direction thereof with respect to a central longitudinal axis of the structure. With respect to the longitudinal axis, the connecting device has a greater thickness in the centre thereof than at its upper and/or lower end.

An inflatable equipment support tower having one or more inflation tubes and inflation valves and equipment mounted in a portable housing, and an equipment platform either mounted on a top of the inflation tubes or configured to move to any point on the inflation tube(s) after full inflation. The housing is configured to be compact and portable, preferably sized to fit inside the trunk or storage compartment of an emergency vehicle. Larger versions may be configured to be towable or mounted on the top of emergency vehicles.

The electric power industry has long standing practices for removal of aged and damaged utility power poles, which are not only time consuming, but unsafe for workers. To address this, the present inventors devised better methods, some of which entail cutting off the top portion of an inground utility pole to produce a pole butt, rotating the inground pole butt about its vertical axis to free the pole from the grip of the surrounding earth, and applying a lifting force to the pole butt during and/or after the rotation. Some embodiments implement the method using a rotary coupler, which couples a rotary drive via one or more pole collaring devices and/or one or more pole penetrating devices, to the pole butt, reducing pole butt removal time by at least half according to some estimates, while also improving safety.

A tower includes a base section; a tower section hinged to the base section; a hinge assembly between the base section and the tower section, the hinge assembly defines a hinge axis about which the tower section hinges relative to the base section; and a flexible cable guide link assembly attached to the tower section such that the flexible cable guide link assembly extends across the hinge axis and into the base section.

Deployable structures are described, in particular linearly-deployable structures, such as masts or booms. The masts may be stowed for transport and then deployed at their destination in space or on earth. A deployment system includes a storage reel storing a stowed elongate band. A drive mechanism biases and guides the band helically out of the storage reel to form an elongated mast. Adjacent edges of the deployed band may secure together using openings and corresponding protrusions, such as rivets. A welding system may use a rotating welder to weld adjacent edges of the band as it deploys. The band may be formed of multiple band segments attached together by connectors such as doublers. Protrusions such as rivets or other fasteners may attach the connectors to opposing sides of the band segments. A cylindrical space habitat or other macrostructure may be formed using multiple deployable masts that connect large rings.
