Arm roller for stringing distribution conductors
View Patent ↗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.
1. An aggregation roller for stringing a conductor over a span, the roller comprising:
a main body, said main body having a first side and a second side and a bottom side, wherein said bottom side is generally flat and said first side and said second side extending away from said bottom in a generally arcuate shape, wherein said body defining an interior, wherein said interior comprising a plurality of rollers positioned in said interior and extending from said first side of said main body to said second side of said main body, wherein said rollers are positioned in said interior in an arcuate shape generally following the arcuate shape of said first side and said second side;
wherein between said first side and said second side and said plurality of rollers defining a groove configured for receiving a length of a power conductive line;
a extension arm extending generally vertically from said second side of said main body to a point generally above a center of said channel defined by said rollers, wherein a gate attached to said extension arm and extends to said first side, wherein said gate is configured to open inwardly when pressure is applied to said gate, wherein said gate is configured to bias closed when pressure is relieved from said arm.
2. The roller of claim 1 , wherein a first flange extends from said bottom side of said main body, said first flange configured for mating engagement with a base configured for mounting to a crossarm.
3. The roller of claim 1 , wherein a second flange attaches to said second side of said main body, wherein said second flange is configured for mating engagement with a base.
4. The roller of claim 1 , wherein the main body comprising a non-conductive material.
5. The roller of claim 1 , wherein a helicopter guide arm attaches to said first side of said main body.
6. The roller of claim 1 , wherein the gate being a spring-loaded gate.
7. The roller of claim 1 , wherein said extension arm defines a rigging hole, wherein said rigging hole is configured for hanging application.
8. The roller of claim 1 , wherein said main body further comprises an outer body, wherein said outer body is configured for enveloping said main body's exterior, wherein said outer body comprise a nonconductive material.
9. The roller of claim 1 , wherein the plurality of rollers being made of a urethane material.
10. The roller of claim 9 , wherein the plurality of rollers being coated with a non-conductive polyurethane.
11. The roller of claim 1 , wherein the plurality of rollers being a number of six.
12. The roller of claim 1 , wherein said plurality of rollers comprise bearings.
