Heavy Duty Two-Pole Strain Carriers (15,000 lb.)
Tested per OSHA & ASTM F711
Two-pole Strain Carriers relieve strain from an insulator string to permit removal from energized lines. Normally used on a single string of insulators, these carriers sometimes are used for multiple strings where conductor-end hardware permits attachment.
Available here as complete assemblies, separate components also may be ordered. For adjustable strain poles, see page 2253; for yokes, sockets and trunnions, see page 2255.
Yokes are fabricated from high-strength aluminum plate and include a steel chain assembly for anchoring the back plate to the structure. Conductor-end yoke includes a hook and a machined socket (C4011894).
Maximum load rating for each of the strain-carrier assemblies listed below is 15,000 lb. per insulator string.
Features:
-Two 2″-diameter Epoxiglas poles
-Yokes are 26″ wide on pole centers
-2-ft. adjustment in 6″ increments on five stainless-steel pins per pole
-12″-long Strain Jacks
