Polymer Sheaves

A sheave is a grooved wheel or pulley that guides or changes the direction of a rope, cable or belt in lifting equipment, cranes, hoists and rigging systems. Nylacast polymer sheaves are listed among its vessel applications for maritime and shipbuilding.

Key features

• Lightweight, for applications where weight is critical
• Not susceptible to rust or corrosion
• Wear resistant in harsh environments and less likely to damage the rope
• Lower coefficient of friction than metal sheaves, requiring less force to move
• Typically less expensive than metal sheaves

Applications

Winch systems, knuckle boom cranes, crawler, tower and mobile cranes, straddle carriers, mobile drilling rigs and vessel deck equipment.
