A pinning attachment device for attaching a stringing block to a structure, such as an insulator of an electrical power distribution or transmission system. The device includes a rigging pin configured to extend through a rigging hole of the structure and a gate movable between an open position and a closed position to secure the rigging pin against withdrawal. The gate is biased toward the closed position and is selectively held open during installation by an actuator, such as a drone arm or removable pin, and automatically closes upon removal of the actuator. A mechanical stop cooperates with the rigging pin to prevent premature withdrawal from the structure prior to closure of the gate. A base portion is configured for connection to a stringing block. The device enables rapid, tool-less installation and removal, including remote installation by an aerial drone, without the use of threaded fasteners or cotter pins.

A portable cross arm support device for temporarily supporting electrical conductors of a power transmission or distribution system. The portable cross arm support is configured for vertical lifting of the conductors. The portable cross arm is configured to fold for facilitating transportation. The portable cross arm has a main support pole mounted in a lifting bracket. Embodiments of the portable cross arm utilize a worm gear lifting system for vertical lifting of the conductors. The cross arm has two opposing horizontal line arms configured to support the electrical conductors. The opposing horizontal line arms extend from a T-connector. The T connector allows the horizontal line arms to pivot to a vertical orientation to provide for folding of the portable cross arm.

What is disclosed is an insulator for providing insulation between a stringing block for an electrical conductor and a pole or cross arm on which the stringing block is mounted. The insulator is made of a non-conductive material such as plastic. The insulator has an upper opening in the body that is configured for receiving a flange of a stringing roller. The insulator can be configured to be mounted directly to a pole or cross arm, such as by using a ratcheting strap. Alternatively the insulator can be configured to be positioned between the roller and a base, such as those known in the prior art.

Grounding attachment for radius block for stringing conductors
A grounding attachment for use with a CRS Roller. The grounding attachment has a body having two arms. Each arm is pivotally attached to the body. The arms are configured to be biased downward onto a conductor positioned on the CRS Roller. Preferably a torsion spring biases the arms downward such that a roller attached to each arm rests on a conductor positioned within the radius block. Energy is conducted from the conductor, through the roller and arm to a grounding lug that is configured for a lineworker to attach a ground to the grounding device to allow the energy to reach the earth.
A connector for connecting a roller to a base for extending a conductor over a span for electrical distribution or sub transmission. The connector is configured to work with pre existing or standard rollers such as a Universal Stringing Roller as well as with embodiments of the inventor's SAR roller, disclosed in a contemporaneously filed United States non-provisional patent application. The connector allows for use of a rotating base disclosed in the contemporaneously pending United States patent application that allows for adjustment of the stringing roller without having to disconnect the stringing roller from the base, whereas in prior stringing roller to base configurations the stringing roller was required to be removed from the base, the string roller rotated, and the stringing roller attached to the base at a new position, typically a flange, on the stringing roller.

A nonconductive line holder for repositioning a conductor for a line worker to safely work. The line holder has a head, a shaft, and a base. The head is configured to receive and secure a conductor. The shaft can be adjustable or nonadjustable. The base is configured to attach to a base. The line holder attaches to the base and allows a line worker to adjust the positioning of a conductor within the head.

An aggregation roller for extending a conductor over a span for electrical distribution. The aggregation roller is useful providing safety for linemen, adaptability to new technologies for conductors, low friction to easily pull the conductors and durability. The aggregation roller is useful in reducing the chances of electrocution of the lineman when the aggregation roller is near energized conductors. Further, the aggregation roller replaces multiple rollers as is used today.
