Pulling Sheaves
- Efficiently transfers power from one source to another
- Reduces wear on ropes or cables
- Helps change the direction of a force
- Increases mechanical advantage
- Provides support and guidance to ropes or cables
Types of Sheave Pulleys
1. Fixed Pulleys
Fixed pulleys have a stationary axle and are used to change the direction of the force applied to a rope or cable.
2. Movable Pulleys
Movable pulleys have a pulley mounted on a movable axle and are commonly used in combination with fixed pulleys to provide mechanical advantage.
3. Compound Pulleys
Compound pulleys combine both fixed and movable pulleys to increase the mechanical advantage even further.
4. Snatch Blocks
Snatch blocks are pulleys that open on one side to easily insert a rope or cable without threading it through.
5. Wire Rope Pulleys
Wire rope pulleys are designed specifically to handle the high loads and stresses of wire ropes.
6. Timing Belt Pulleys
Timing belt pulleys are used with timing belts to transmit power in machines and vehicles with precise synchronization.
What is a sheave on a pulley
- A sheave is a wheel with a groove used in conjunction with ropes or cables
- It helps change the direction or magnitude of a force applied to the rope or cable
- Sheaves can be made of various materials such as metal, plastic, or composite
- They are commonly used in lifting and pulling applications
- Sheaves come in different sizes and designs to suit specific needs
What are sheaves used for?

Process of Sheave Pulley
Mold
The mold for sheave pulleys is created to form the desired shape and structure.
Casting
Raw materials are melted and poured into the mold to create the sheave pulley.
Raw Materials
Sheave pulleys are typically made from durable materials like steel, aluminum, or nylon.
Production
The production process involves shaping, machining, and assembling the sheave pulley components.
Testing
Sheave pulleys undergo rigorous testing to ensure they meet quality and safety standards.
Antirust Treatment
To prevent corrosion, sheave pulleys may receive a special antirust treatment.
Separate Inspection
Each sheave pulley is individually inspected for defects or imperfections.
Marking
Sheave pulleys are marked with specifications and details for identification and tracking.
How do you adjust sheave pulleys?
- Identify the problem or need for adjustment
- Loosen the fasteners or mechanisms holding the sheave in place
- Adjust the position of the sheave to the desired location
- Secure the sheave in place by tightening the fasteners
- Test the sheave pulley to ensure proper alignment and function
- Make further adjustments if necessary
- Regularly inspect and maintain sheave pulleys for optimal performance
