    "data": {
        "note": "A winch's rated pull is for the first (bare-drum) layer; as rope piles on, the effective lever arm grows, so the line pull falls and the line speed rises in the same ratio — pull × (first-layer diameter ÷ this layer's diameter). On a deep drum the top layer can pull barely half the bottom-layer rating, which is why you spool off to the bare drum for a hard pull, or add a snatch block.",
