The Tulip Sheaves are fixed sheaves that do
not turn in the direction of manoeuvres since
they accept quite different lead angles.
The choice of a Tulip sheave instead of a
revolving block comes from the need to reduce
bulk and weight.
The sheave, with an axial bearing in composite
fibre and large round bearings (self-captive)
in Torlon for side loads, is in anodized and
Teflon coated aluminium and can handle very
high loads.
