TABLE 8.2: ROLLERS FOR FAIRLEADS

8.6 UNIVERSAL ROLLER FAIRLEADS

Universal roller fairlcads consist of several cylindrical rollers, or a combination of roUers and curved
surfaces. Possible arrangements are shown in Figs. 8.2, 8.3 and 8.4. Further details may be found in
BS MA 23.

The basic four-roller type may have 10 be modified to suit extreme inboard or outboard line angles.
Sometimes the inboard lead lo the winch or bollard requires an additional vertical roiler, or in rare
cases, two additional vertical rollers as shown in Fig. 8.4. Extreme outboard angles can be accom-
modated with chafe plates as shown in Fig. 8 .3.

Some line angles are impraclical and seldom occur. For example, the inboard lead seldom runs in an
upward direclion and the outboard angle is upward only at terminals wi[h a large difference in [ide
or when moored in canal locks. In this case the Type C shown in Fig. 8.2 would be adequate and
result in a lower overaU height of the fajrlead.
