49、nt. Reach is equal to lift plus headroom (seeFig. 6-0.2-1).reeving: a system in which the wire rope travels aroundsprockets (see Fig. 6-0.2-2).double reeving: reeving in which two parts of the linelead off of the drum.single reeving: reeving in which one part of the lineleads off of the drum.rope: refers to wire rope unless otherwise specified.NOTE: Rope properties do not conform to those shown inASME B30.9.
