Types of Sheave Pulleys

Fixed Pulley

A fixed pulley is attached to a stationary point and does not move. It changes the direction of the force applied to the rope or cable.

Movable Pulley

A movable pulley is attached to the object being moved and moves with it. It reduces the amount of force needed to lift the object.

Compound Pulley

A compound pulley combines both fixed and movable pulleys to provide mechanical advantage, making it easier to lift heavy loads.

Block and Tackle Pulley

A block and tackle pulley system consists of multiple pulleys arranged in a block and tackle configuration to provide increased lifting force.

Snatch Block Pulley

A snatch block pulley is designed to be easily attached to a rope or cable to change the direction of the force and increase mechanical advantage.

Wire Rope Pulley

A wire rope pulley is specifically designed to work with wire ropes, providing smooth operation and efficient lifting capabilities.

What is a sheave on a pulley

  1. A sheave on a pulley is a wheel with a groove around its circumference where a rope or cable can run.
  2. It is designed to change the direction of the force and transmit motion or power.
  3. Sheaves on pulleys can be made from various materials such as steel, aluminum, or plastic.
  4. Sheaves come in different sizes and configurations to accommodate different rope or cable diameters.
  5. They are essential components in pulley systems for lifting, lowering, or transmitting power.
