Types of Sheave Pulleys

1. Single Sheave Pulleys

Single sheave pulleys have only one wheel to support the rope or cable.

2. Double Sheave Pulleys

Double sheave pulleys have two wheels to support the rope or cable, providing increased mechanical advantage.

3. Triple Sheave Pulleys

Triple sheave pulleys have three wheels to support the rope or cable, offering even greater mechanical advantage.

4. Fixed Eye Sheave Pulleys

Fixed eye sheave pulleys have a stationary eye for easy attachment.

5. Swivel Eye Sheave Pulleys

Swivel eye sheave pulleys have a rotating eye for flexibility in different directions.

6. Snatch Blocks

Snatch blocks are specifically designed for heavy loads and can rotate 360 degrees.

What is a sheave on a pulley

  • A sheave is a wheel with a groove used to guide a rope or cable.
  • It helps change the direction of the force applied to the rope or cable.
  • Sheaves reduce friction and wear on the rope or cable.
  • They are commonly used in pulley systems for lifting or pulling loads.
  • Sheaves can be made of various materials such as metal, plastic, or ceramic.
