Antal realizes a special line of deck blocks which mount Tulip sheaves. Tulip sheaves have a particular groove shape that allows a line lead angle range of 40°.
Torsion loads are borne by large lateral ball bearings. Low friction is thus always guaranteed even when the line is deflected.
Tulip deck blocks include Tulip foot blocks, Tulip organizers, Tulip vertical blocks and Tulip turning sheaves. Also spare Tulip sheaves are provided for custom applications.
