A method of modular pole construction an elongate modular pole structure is disclosed. A first step of the method involves providing hollow tapered pole section modules, each module having a first open end and an opposed second open end. A cross-section of the second end is less than a cross-section of the first end. The modules are stacked to form an elongated modular pole structure of a selected length by mating the second end of a first module with the first end of a second module. The first and second modules may have different structural properties, such that poles having desired structural properties can be constructed by selectively combining modules having differing structural properties.

In an aspect, the present disclosure describes a system for constructing a solar module array. The system can comprise one or more mobile platforms; one or more carriers operatively coupled to the one or more mobile platforms, wherein the one or more carriers support a plurality of posts and/or a plurality of solar modules; one or more robotic components for retrieving one or more posts from the plurality of posts and one or more solar modules from the plurality of solar modules from the one or more carriers; and at least one controller in operative communication with the one or more mobile platforms and the one or more robotic components, wherein the at least one controller (i) directs the one or more mobile platforms to transport the one or more carriers over a terrain and (ii) controls the one or more robotic components to (1) autonomously position and install the one or more posts on the terrain, and (2) autonomously position and assemble the one or more solar module to the one or more posts installed on the terrain to thereby construct the solar module array on the terrain.

The present disclosure describes a base structural building module employing a core structural member having an array of upwardly and outwardly and downwardly and outwardly extending braces or arms extending therefrom. Tubular cans are mounted at the ends of each of the upper and lower arms to receive piles. One upper arm is aligned and paired with one lower arm and the pair's respective cans are aligned about their can axis. The modules employ flexible design by varying the lengths of the arms and their respective inclination or declination angles. Modules can be stacked one on top of another (and secured) to form multi-tiered structural building jackets for building vertical structures such as, for example, oil and gas platforms used onshore or offshore as well as other structures. Each tier can also comprise multiple modules joined laterally together to provide a wide variety of potential template configurations and building applications.

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 pushing-out apparatus for an extendible mast includes a mast storing unit, a mast pushing-out unit and a mast pushing-out driving unit. The storing unit stores an extendible mast including stages of foldable trusses in a state that the stages are folded. The pushing-out unit is stored in the storing unit around the stage-folded mast stored in the storing unit. The driving unit moves the pushing-out unit to a projecting position in an outside of the storing unit while the stages of the mast are folded, sequentially extend out the folded stages of the mast stored in the storing unit by the pushing-out unit from the storing unit and push out the extended stages from the pushing-out unit of the projecting position in a side of the pushing-out unit opposing to the storing unit.

A stackable enclosure for support of a mast stored in horizontal position and rotatable to a vertically deployed position. The enclosure employs a housing have sidewalls constructed and arranged to support a plurality of stacked enclosures. The dimensions of the enclosure with wheels can allow for the transporting of thirty units on a single 48 drop deck trailer. The enclosure has a hinged lid to allow ease of access to the interior which can house a power system to operate a bank of lights. Outriggers positioned along each corner of the enclosure provide stability to the mast in high winds. A hinged axle can be used to pivot enclosure wheels upward, allowing the enclosure to rest flush on a trailer deck or ground surface.

The disclosure relates to a pole setting device to assist in setting a utility pole in a base while maintaining electrical isolation between the utility pole and a worker, the device having: a non-electrically conductive elongate member having a handle end and an opposite pole end, and having a length between the handle end and the opposite pole end; a bracket adapted to contact to an exterior surface of the pole and to the pole end of the non-electrically conductive elongate member.

An object of the present invention is to provide a pole erection method capable of efficiently and safely erecting a utility pole with a small number of operators even in a construction environment in which heavy machines cannot be used.

The pole erection method according to the present invention includes preparing a structure 60 having a cylindrical shape in which, when the structure is erected perpendicularly to the ground with one end 60a facing down, a part of an edge 61a at the other end 60b is higher than the other part of the edge 61b (step S01), burying one end 60a of the structure 60 in the ground (step S02), placing a lower end portion 10a-1 of a utility pole 10a lying on the ground on the other part of the edge 61b of the structure 60 (step S03), pressing the lower end portion 10a-1 of the utility pole 10a against an inner wall 62 (step S04), and lifting up an upper end portion 10a-2 of the utility pole 10a with the other part of the edge 61b as a fulcrum while pressing the lower end portion 10a-1 of the utility pole 10a against the inner wall 62, and sliding down the utility pole 10a into a cavity 63 of the structure 60 to erect the pole (step S05).
