    • A stringing block for aerial electric conductor or other aerial, cable, intended for hanging to electric line structures, insulators etc., suitable for both manual and helicopter pilot line or conductor stringing, is disclosed. The block comprises one or more ring-shaped sheaves, each one running over one or two small wheels, installed on a small size frame and rotating around their axes. The block is light enough, for to prevent conductor/pilot line escaping the shave groove and friction on the shave flange. Additionally, a stringing block with hanging point, shifted from the sheave groove centre plane, is disclosed. This shift helps to minimize the conductor friction on the shave flange, especially for the blocks with wide groove.
