Pulleys (and rings) are key elements in the nautical industry, enabling you to transmit forces, orient ropes, guide, or create hoists, indispensable accessories for rigging and sail trimming. In recent years, these blocks have evolved towards a new, more efficient fastening method than the stainless steel swivel shackle: lashing and the Dyneema® textile shackle.
Advantages:
Among the advantages of textile-fastened pulleys is the fact that forces pass directly through the center of the pulley - the sheave - which improves strength and reduces the risk of breakage.
Other advantages of textile-fixed pulleys include
- Versatility of use, thanks to their flexible attachment system
- If the sheave breaks, the load is held by the lashing or textile shackle.
- Shape and design of pulleys require fewer parts
- Lighter and stronger
- No corrosion or maintenance
- Automatic load alignment
It's important to check that the lashing or textile shackle is attached to a trigger guard or chainplate with rounded edges.
