A bundle lifter for lifting a sub-conductor bundle having a plurality of spaced-apart sub-conductors, includes a base platform adapted for rotational mounting onto a single point conductor lifter, four sub-conductor wire cages mounted on the platform to support a sub-conductor thereon, each wire cage adapted to releasably hold a single sub-conductor and to swivel relative to the platform, wherein when the wire cages are positioned under the sub-conductor bundle, the wire cages are swivelled to align their corresponding rollers with a corresponding sub-conductor for rolling support of the sub-conductor on the roller as the bundle lifter is elevated on the support upwards from under the sub-conductor bundle to simultaneously pick each sub-conductor in the bundle into its wire cage for translation of the bundle from an original position to a new position spaced apart from the original position.

A laser processing apparatus 1 includes a laser head 31, a flexible cable 6 connecting a laser oscillator and the laser head 31 to each other, a conveyance apparatus 2 that conveys a workpiece W, a head drive mechanism 5 that moves the laser head 31 to a processing position, and a cable support mechanism 7 that moves the cable 6 in association with movement of the laser head 31. The cable support mechanism 7 includes a first holder 61 holding the cable 6, a first spring balancer 711 connected to the first holder 61 through a first wire 712, and a second spring balancer 721 connected to the first holder 61 through a second wire 722. The spring balancers 711, 721 are fixed to a support frame 8, and as viewed in plane, are arranged in a line along a width direction X perpendicular to a conveyance direction Y.

A clamp for supporting an electrical conductor on a structure and providing electrical continuity between the electrical conductor and the structure is provided. The clamp can include a mounting member with a through-hole and a strap, that can be configured to extend around the structure, coupled on one end to a first side of the mounting member and having a free end removably coupled to a second side of the mounting member. The clamp can include a clamping member with a through-hole and a main bolt extending through the through-holes of the mounting member and the clamping member. The main bolt can have a footer configured to contact the structure, which can be movable between a first configuration in which the footer is nested within a pocket of the mounting member and a second configuration in which at least a portion of the footer is positioned outside of the pocket.

A drop wire clamp to secure a cable that comprise an outer shell and an inner wedge. The outer shell having a first wall, a second wall, and a shell base to couple the first wall with the second wall. The shell base further defines a shell channel. The inner wedge is receivable in the outer shell and movable between a first position and a second position within the outer shell. The inner wedge has a wedge base defining a wedge channel, wherein the shell channel aligns with the wedge channel in the second position to form a containment structure to house a cable therein. The containment structure includes a length dimension and a width dimension, wherein the length dimension is greater than the width dimension and the length dimension extends in a same direction as the first wall and second wall of the outer shell.

Cable support devices and assemblies are provided. A cable support device supports multiple fiber-optic cables on an above-ground pole. A cable support device includes a base, and a first arm and a second arm extending from the base, the first arm and second arm generally parallel to each other. The cable support device further includes a cross-member extending between and connected to the first arm and the second arm. The cable support device further includes at least one divider member extending radially outwardly from the cross-member, the at least one divider member spaced from the first arm and the second arm and defining at least two slots, each of the at least two slots further defined by the cross-member.

An insulator pin for overhead electrical lines has a frangible portion. The pin has an elongate support for attachment to an electrical distribution pole and a body. The body has a connector for an insulator, a frangible portion and an elongate support holding portion from which the elongate support extends. Preferably the elongate support is a bolt. The frangible portion permits the body to break into two pieces for preventing damage to electrical distribution poles from forces transverse to the overhead electrical line. The frangible portion is located between the connector and the elongate support holding portion. The insulator pin may be attached to an electrical distribution pole to protect the pole from forces transverse to an overhead electrical lines supported by the pole. A method of making the insulator pin by molding is disclosed.

A grounding system, structured to ground a number of cables supported by a support assembly, includes a multi-function line assembly and a number of conductive mounting assemblies. Each conductive mounting assembly is structured to be coupled to the multi-function line and to a conductive pile.

A low-PIM, stackable polymeric cable hanger spacer that includes a polymeric base forming a rim that defines a latch surface for capturing locking metal barbs of interface brackets of a metal snap-in cable hanger. The spacer also includes polymeric legs extending from the polymeric base with polymeric barbs for latching to an adjacent snap-in cable hanger or other support member. The base allows the metal barbs to pass through the base when the metal barbs are deflected or compressed toward each other. and then allows the metal barbs to spring back to engage the latch surface and become captured by the polymeric spacer once the metal barbs clear of the rim. The base may have a round toroidal shape with rounded edges allowing the metal snap-in cable hanger to rotate with respect to the spacer.

A clamp for suspending an aerial conductor wire from a transmission tower includes an inner sleeve formed by a pair of sleeve halves which are mated and fastened together to define a cylindrical open-ended conductor bore for compressing the conductor wire, the inner sleeve having outer enlarged ends each forming an opposing shoulder, and an outer sleeve formed by a pair of outer sleeve halves which mate together to define an inner bore which closely fits an outer diameter of the inner sleeve and having a length which fits between the opposing shoulders of the inner sleeve, to permit rotation of but restrict longitudinal movement of the inner sleeve within the outer sleeve, wherein each outer sleeve half each comprises an interlocking assembly which mates with an interlocking assembly on the other half and a mounting tab on an longitudinal edge opposite the interlocking assembly.
