What is a sheave on a pulley

A sheave on a pulley is a wheel with a groove used to guide the rope or cable, providing mechanical advantage and facilitating the movement of loads. It helps to change the direction of force applied and support the weight being lifted.

What are sheaves used for?

1. Load Distribution

Sheaves are used to distribute the load evenly across multiple ropes or cables, reducing strain and increasing efficiency.

2. Direction Change

Sheaves help to change the direction of the force applied, allowing for easier movement of loads in different directions.

3. Mechanical Advantage

Sheaves provide a mechanical advantage by increasing the force applied to lift heavy loads, making tasks easier and more manageable.

4. Support and Guidance

Sheaves support and guide ropes or cables, ensuring smooth movement and preventing tangles or snags during operation.

5. Tension Adjustment

Sheaves are used to adjust the tension in ropes or cables, allowing for precise control and adjustment during lifting and lowering operations.

6. Multipurpose Applications

Sheaves are versatile and can be used in a wide range of applications, from construction and window washing to industrial machinery and transportation systems.
