TULIP SERIES SHEAVES

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.

VERTICAL TULIP BLOCKS

These vertical blocks are fitted with Tulip sheaves that accept very different lead angles.
This is a small and light solution that replaces traditional adjustable blocks.
Mounting screws, nuts and washers included.

More vertical blocks can be joined to form a set.

TURNING TULIP SHEAVES

This sheave is fitted with 4 wide Torlon ball bearings, this is the best solution when it is necessary to redirect the line to any angle.
