An expandable modular energy-dissipation protection net unit group includes support columns each provided at each of two ends of each support column with a first horizontal longitudinal rotation reversing device on the left side, a second horizontal longitudinal rotation reversing device on the right side and a transverse rotation reversing device on the bottom; a transverse endless support rope, a longitudinal endless support rope and connectors. The transverse endless support rope is wound on the transverse rotation reversing device. The longitudinal endless support rope is wound on the first horizontal longitudinal rotation reversing device and the second horizontal longitudinal rotation reversing device adjacent. A metal net panel is tied by the plurality of connecting members and hung on the transverse endless support rope and the longitudinal endless support rope.

A wire fence tool and method, the tool being an elongated rod with a loop and hole, end to end) in the center section that is used to rotate strand(s) of wire that placed in the hole to tighten broken wire strands or wire splice strand, and method for repair fence wire with the tool.

A cable gripping and tensioning apparatus is provided for attaching a cable to an anchor point such as a wooden post as part of a cable railing system. In one form, the apparatus includes a tubular component and a ferrule. The tubular component includes external threads to engage the wall of a hole in the post, an internal axial bore through which a cable may pass, a first end which may engage a wrench to rotate the tubular component and a second end which may provide a thrust bearing surface. The ferrule is swaged to an end portion of the cable. The ferrule provides a thrust bearing surface for contact with the second end of the tubular component, allowing for the rotation of the tubular component to tension the cable while the cable does not rotate.

A fence installation system for automating the fence installation process includes a trailer apparatus. A post dispenser apparatus is configured to secure a plurality of fence posts. A post holder apparatus comprises a first robotic arm and a claw configured to secure a fence post. A post hole drill apparatus is coupled to the trailer apparatus and comprises a second robotic arm, a drill head, and an auger bit. A post driver apparatus comprises a third robotic arm and a driver head configured to drive the fence post into the ground. A fence wiring apparatus comprises a spool axle and a plurality of wire spools coupled to the spool axle. A control apparatus is in operational communication with each of the post holder apparatus, the post hole drill apparatus, the post driver apparatus, and the fence wiring apparatus.

The present invention relates to a device for installing a fence. In most embodiments the device comprises three main areas: the driver area, the installer area, and the storage area. The driver area is where the driver of the device is located and comprises the necessary components to drive the device, such as a motor and steering mechanism. The installer area is where the fence installer is located, and in most embodiments is placed above the driver area so that the installer can access the top rail of the fence during installation. The storage area is where the fencing material is placed, often times as a roll. This roll is fed out of the storage area and installed by the installer while the device is driven down the length of the fence. This device beneficially decreases the amount of time and man-power required to install a fence.

The invention provides components for an electric fence. The components are made of a composite material including a derivative or a combination of minerals and a polymeric material.

A machine for making a knotted wire fence, including a machine frame, at least one knot box, at least one drive shaft, and a drive shaft driving means, wherein the machine can be switched between a first configuration in which the machine can be used to produce a knotted wire fence incorporating a first knot type, and a second configuration in which the machine can be used to produce a knotted wire fence incorporating a second knot type.

A safety fence comprising a first and a second post. An upper rail is securable to upright members of the first post and the second post in a horizontally orientation. A mesh has an upper end slidably coupled to the upper rail. The mesh has a retracted configuration where it is collapsed and retained next to the first post, and a deployed configuration where it is extended between the first and second posts in a taut configuration. At least one tensioning member has a first end fixed to the first post and is releasably securable to the second post such that the tensioning member may be tensioned between the first and second posts. The tensioning member, when tensioned between the first and second posts with the mesh in its deployed configuration, provides horizontal load support to the mesh.

A metal net having entwined metal wires defining the meshes of the metal net comprises at least one elongate sensor element fixed integrally to the metal net, inserted into the net during the production thereof. The elongate sensor element may comprise a wire of a material having a low coefficient of variation of the resistivity and a high gauge factor, preferably formed from constantan, or else may be of the optical fibre or composite fibre type.
