A fitting for channel framing includes a first clip arm configured to extend into a first external fitting groove of the channel framing and clip onto the channel framing, and a second clip arm configured to extend into a second external fitting groove of the channel framing and clip onto the channel framing. An outer portion connected to and extending between the first and second clip arms is configured to span across the continuous slot when the first and second clip arms extend into the respective first and second external fitting grooves and are clipped onto the channel framing.

Embodiments of the invention provide a number of passive and active defense designs and methods that enable a wind turbine to escape high wind events. The disclosure includes descriptions of multiple designs and methods for lowering the elevated portion of a wind turbine. Other embodiments of the invention concern ways to connect the elevated portion of a wind turbine to the tower. Numerous counterweight systems are also disclosed which enable the lowering of the elevated portion of the wind turbine.

A fencing/railing assembly adapted to be positioned between a pair of posts and mounted thereto includes a plurality of pickets, a plurality of rails extending transverse to the pickets, and one or more pivoting, sliding connectors for connecting a picket to a rail, with the sliding, pivotal connection concealed by the rail. The connector is slidably mounted to the rail and is pivotally connected to the picket. In one embodiment, an elongated connector strip is concealed by the rail and spans multiple pickets. In another embodiment, the assembly includes a plurality of shorter connectors, one for each picket/rail connection.

A fitting for hanging a piece of channel framing includes a coupling component having opposite longitudinal ends, a length extending between the opposite longitudinal ends, a coupling longitudinal portion configured to be secured in the external fitting groove of the channel framing body, and an exposed longitudinal portion configured to extend outward from one of the open groove ends of an external fitting groove for connection to a rod to hang the piece of channel framing from an elevated structure when the coupling longitudinal portion of the coupling component is received in the external fitting groove.

A system for manufacturing homes is provided. An embodiment includes a sub-assembly plant for assembling planar sections of a home according to production schedule for custom homes. The embodiment also includes at least one final assembly facility located proximal to a subdivision where a plurality of the custom homes are to be situated. The final assembly facility is for receiving the planar sections from the sub-assembly plant and for constructing the homes from planar portions according to the production schedule.

A rigging table and system for assembling trusses using a rigging table. An embodiment of a rigging table includes a base having a generally longitudinal axis and a generally lateral extent, and at least two bunk assemblies moveable along the base in at least the generally longitudinal axis such that each bunk assembly is capable of being positioned on the base relative to another bunk assembly. Each bunk assembly may include a frame extending along the lateral extent of the base, a pair of guides slidably positioned on the frame to move generally transverse to the longitudinal axis of the base toward and away from each other and able to be fastened in position on the frame, and a pair of automated clamp members each positioned relative to and moveable with one of the guides on the frame, to accommodate assembly of different sized trusses.

Embodiments of the invention relate to a rigging table system that delivers the members from the cutting station to a location behind the workers at the rigging table, transports the members vertically below the surface of the floor on which the workers stand, horizontally transports the members underneath the floor on which the workers stand, and delivers the members vertically above the surface of the floor in front of the workers for assembly on the rigging table. The members are delivered through the use of systems that drop, slide, lift, and extend the members of the truss to the desired locations using automatic sensors or call buttons.

Described herein is a mounting system and slider clips that support simplified installation of photovoltaic structures. The mounting system comprises a support structure which can be mounted to support columns via an optional tilt table. The support structure comprises a plurality of parallel spaced beams and a plurality of parallel spaced rails that are mounted approximately perpendicular to the beams. Disclosed embodiments describe a collapsible support structure in which the rails are pivotally mounted to the beams. Rails are preassembled with prefabricated slider clips for holding edge portions of the photovoltaic structures. Rails can also be integrally formed with slider clips. Described herein are also methods of installing one or more photovoltaic structures using the mounting system and methods for manufacturing slider clips and a photovoltaic structure mounting system.

A fencing/railing assembly adapted to be positioned between a pair of posts and mounted thereto includes a plurality of pickets, a plurality of rails extending transverse to the pickets, and one or more pivoting, sliding connectors for connecting a picket to a rail, with the sliding, pivotal connection concealed by the rail. The connector is slidably mounted to the rail and is pivotally connected to the picket. In one embodiment, an elongated connector strip is concealed by the rail and spans multiple pickets. In another embodiment, the assembly includes a plurality of shorter connectors, one for each picket/rail connection.

Embodiments of the invention comprises a truss assembly and a method for assembling the truss assembly. The truss assembly includes V-shaped longitudinal supports forming corners of an elongated truss located at each angle of a polygonal axial cross-section. Open webs are fixedly attached between each adjacent V-shaped longitudinal supports extending the length of the elongated truss. The open webs have a plurality of bends in a same plane, and the plurality of bends are welded to a portion of the inner surface of adjacent V-shaped longitudinal members without having to place jigs or bracing to form the open web or to secure the open web to the two V-shaped longitudinal members. The elongated support truss may have a triangular cross-section, a rectangular cross-section, a square cross-section, a pentagonal cross-section, or the like.
