Four Sheaves Combined Block for Power Line Stringing

The Four Sheaves Combined Block is a professional cable stringing tool designed for overhead transmission line construction, conductor installation, and cable pulling operations. It consists of four sheaves mounted on a combined frame structure, allowing smooth conductor guidance during stringing processes.

The multi-sheave design helps distribute pulling force evenly, reduce cable friction, and protect conductors from unnecessary bending or surface damage. The roller frame is manufactured with a durable metal structure, while the sheaves are designed for stable rotation under continuous pulling conditions.

This combined block is widely used in power transmission projects, electrical infrastructure construction, and overhead line maintenance where reliable cable guidance and efficient installation are required.
