What is a Sheave on a Pulley?

  • A sheave is a wheel with a grooved rim around which a belt, rope, or chain passes to change the direction or point of application of a force.
  • Sheaves are commonly used in pulley systems to provide mechanical advantage and facilitate lifting or pulling loads.
  • They are essential components in rigging setups to support and guide ropes or cables for smooth and efficient operation.
  • Sheaves come in various sizes and configurations to suit different applications and load capacities.
  • They play a crucial role in distributing weight and reducing friction in rigging systems.

What are Sheaves Used For?

  • Sheaves are used to change the direction of a force in rigging systems.
  • They help to support and guide ropes or cables in lifting and pulling operations.
  • Sheaves provide mechanical advantage by increasing the length of rope in contact with the pulley.
  • They reduce the amount of force required to lift heavy loads in theatrical rigging setups.
  • Sheaves help to distribute weight evenly and minimize wear on ropes or cables.
  • They contribute to the smooth and efficient operation of rigging systems in theatrical environments.
