Sheave for electrical stringing block

An electrical stringing block for stringing a conductor to a tower or powerpole, comprising:

• an axle;
• at least one bearing mounted on the axle;
• at least one metal sheave mounted on the axle by the at least one bearing, the sheave being rotatable relative to the axle, the at least one metal sheave comprising a pair of metal plates,
• each plate comprising an inner rim section having first and second edges and a length defined therebetween, an angled section having inner and outer edges and a length defined therebetween, a planar section having inner and outer edges and a length defined therebetween, and a curved section having inner and outer edges, the inner edge of the angled section extending from the second edge of the inner rim section at a corner, the outer edge of the angled section extending from the inner edge of the planar section, each angled section being continuous, the inner edge of the curved section extending from the outer edge of the planar section,
• the plates being joined together at the planar sections and forming a central aperture therethrough which is defined by the inner rim sections, the first edges of the inner rim sections facing each other, the axle being mounted through the central aperture, the central aperture defining a centerline therethrough, wherein each inner rim section extends in a direction parallel to the centerline, wherein each planar section extends in a direction perpendicular to the centerline;
• the at least one bearing engaging with at least one of the inner rim sections of the plate;
• and
• at least one support arm attached to the axle configured to support mounting the electrical stringing block to an associated tower or powerpole.
