Abstract: Provided is a lattice boom in which a desired part can be reinforced after the lattice boom has been assembled and in which workability of the reinforcement can be improved. The lattice boom includes a plurality of main pipes, a plurality of lattice pipes, and a reinforcing part. The reinforcing part is provided on at least one of the outer circumferential surface of the main pipe and the outer circumferential surface of the lattice pipe. The reinforcing part is arranged between adjacent connecting parts among a plurality of connecting parts each connecting the main pipe and the lattice pipe. The reinforcing part includes a plurality of reinforcing members arranged along the circumferential direction of the pipe.

Abstract: A truss system designed to simplify the addition of lights, audio equipment, and other stage-related equipment through the use of essentially circular strut channel members. The system is designed to enclose such equipment, be lightweight, and facilitate easy set-up and take-down of truss assemblies. The lightweight truss system includes an open-sided structure with rigid ends, and a strut channel system that facilitates the installation of lights, audio equipment, and other stage-related devices.

Abstract: A tower includes an outer portion forming an outer covering for the wind turbine tower and an inner portion disposed within the outer portion. The inner portion includes a preassembled power module including an upwardly extending support and electrical components that extend outwardly beyond the upwardly extending support and guide supports coupled at a first end to the upwardly extending supports and extending outwardly beyond the electrical components.

Abstract: The elongated box frame structure of the present invention comprises a plurality of frame segments attached to at least one end piece. Preferably, two end pieces are attached, one at each end of the plurality of frame segments. The plurality of frame segments are attached to the end piece such that a column-like structure is formed. The inner space defined within the frame segments is substantially free of webbing. Instead, structural strength and stability is achieved by the attached end pieces. The end pieces of one elongated box frame structure are capable of removably connecting with the end piece of other similar elongated box frame structures to achieve varying framing heights and other dynamic configurations.
