Types of Sheave Pulleys

1. Fixed Pulleys

Fixed pulleys have a stationary axle and are used to redirect force in a single direction.

2. Movable Pulleys

Movable pulleys have a movable axle and are often used in mechanical advantage systems.

3. Compound Pulleys

Compound pulleys combine fixed and movable pulleys to increase lifting force.

4. Block and Tackle Pulleys

Block and tackle pulleys consist of multiple pulleys working together to provide mechanical advantage.

5. Idler Pulleys

Idler pulleys are used to route belts or chains for proper operation.

6. Snatch Blocks

Snatch blocks are used for lifting heavy loads and changing the direction of a rope.

What is a sheave on a pulley

1. A sheave is a wheel with a groove

The sheave on a pulley is a wheel with a groove designed to hold a belt, rope, or cable.

2. It helps change the direction of force

By providing a surface for the belt or rope to run on, the sheave helps change the direction of force.

3. It provides mechanical advantage

Sheaves can be used to provide mechanical advantage by increasing the force applied to the load.

4. It reduces friction

The smooth surface of the sheave helps reduce friction between the belt or rope and the pulley.

5. It supports heavy loads

Sheaves are designed to support heavy loads and ensure smooth operation of the pulley system.

What are sheaves used for?

1. Lifting and lowering objects

Sheaves are commonly used in lifting and lowering applications to move heavy objects vertically.

2. Transmitting power

Sheaves can transmit power between shafts by using belts or ropes to connect the pulleys.

3. Changing the direction of force

Sheaves help change the direction of force in a pulley system to achieve the desired movement.

4. Tensioning belts and ropes

Sheaves are used to maintain proper tension in belts and ropes to ensure efficient operation.

5. Supporting rotating shafts

Sheaves support rotating shafts and provide a surface for belts or ropes to run on.

6. Increasing mechanical advantage

By using multiple sheaves, mechanical advantage can be increased to lift heavier loads with less force.

Process of Sheave Pulley

The mold is prepared according to the design specifications for the sheave pulley.


The molten metal is poured into the mold to create the desired shape of the sheave pulley.

Raw Materials

High-quality raw materials are used to ensure the strength and durability of the sheave pulley.


The sheave pulley is manufactured using precision machinery and advanced technology.


Rigorous testing is conducted to ensure the sheave pulley meets quality standards and specifications.

Antirust Treatment

The sheave pulley undergoes antirust treatment to protect it from corrosion and extend its lifespan.

Separate Inspection

Each sheave pulley is individually inspected to guarantee quality and performance.


Final marking is done on the sheave pulley for identification and traceability purposes.

How do you adjust sheave pulleys?

1. Loosen the set screws

Start by loosening the set screws on the sheave pulley to allow for adjustment.

2. Adjust the position

Move the sheave pulley to the desired position by sliding it along the shaft.

3. Realign the belt or rope

Ensure the belt or rope is properly aligned with the sheave pulley for smooth operation.

4. Tighten the set screws

Once the adjustment is made, tighten the set screws to secure the sheave pulley in place.

5. Test the operation

Test the sheave pulley to ensure it is functioning correctly after the adjustment.

6. Make fine adjustments

If necessary, make fine adjustments to optimize the performance of the sheave pulley.
