Manufacturer's data

Size — Nominal size as the manufacturer states it. Rope size — Rope diameter the sheave is made for. WLL — Working load limit — the most the part may carry in service, as the manufacturer rates it. L — Dimension L on the manufacturer dimension drawing. N — Dimension N on the manufacturer dimension drawing. Q — Dimension Q on the manufacturer dimension drawing. Y — Dimension Y on the manufacturer dimension drawing. Weight — Weight as the manufacturer publishes it. Ask us for the dimension drawing if you need it stamped.
WLL is the most the part may carry in service. Proof and breaking loads are test figures — never lift to them. Each load is shown in the unit the manufacturer rates the part in, and a size ships with the manufacturer’s test certificate.
