How to Configure Block & Tackle
- 1). Attach one of your two multi-pulley blocks to the load to be lifted. (The double-pulley blocks listed in Resources have eyelets to attach to the load.)
- 2). Attach the second pulley block to a stationary support, preferably directly above the load if you're lifting it vertically. That way no force is wasted on lateral tension. This is also why the pulleys are in a block instead of spread out: to avoid wasted energy through lateral tension. Denote the load end of the tackle End A and the pulling end End B.
- 3). Thread End A over one of the pulleys in the hanging block. Pull the end down to the load-attached block and thread it under one of the pulleys in that block.
- 4). Continue threading End A up and down, over the hanging block's pulleys and under the load-attached block's pulleys, until each pulley has tackle running through. Then pull End A to the opposite block again and knot it to the unused eyelet. (The blocks in Resources have two opposite eyelets for this purpose.)
- 5). Lift the load by pulling End B.
