remove the wedge from the socket and allow the cable
to assume its natural position and to eliminate the initial
twist that a new cable may develop.
e. Measuring Cable and Sheave Throat.
For
prolonging cable life, the diameter of a new cable should
be slightly smaller than the sheave groove diameter.
Cable diameter is measured across the flats (fig. 11).
Since the cable diameter decreases through wear, it will
have a tendency to wear the cable groove in the
sheave. If a new cable is installed on sheaves with worn
grooves, rapid wear to the new cable will result. Cable
sheaves and lagging should be checked periodically by
using a cable gauge to see if the sheaves need
replacing (fig. 12).
