Sheave Block Overview | Snatch Block Pulley for Rigging & Winch Lines

Learn how sheave blocks — also known as snatch blocks or pulley blocks — make lifting, pulling, and rigging safer and more efficient. In this video, the LGH team breaks down how these heavy-duty pulleys help redirect lines, reduce force, and increase control on your job site.

A sheave block uses one or more grooved wheels to change the direction of a rope or wire rope. A snatch block is a specific type of sheave block that opens on one side, letting you insert the line without feeding it through the end — saving major time on the job.
