 Aluminum Plastic Pulleys
with red sheaves. Made in India

These pulleys are made of rigid colored plastic with deep V-grooves.  They are balanced for free movement and have a 50 mm diameter.

They are mounted on aluminum strips with hooks at both ends.  These pulleys are often used as parts of compound machines.  They function as helper machines, easing the lifting power. Aluminum frames are not attracted by magnets, so these pulleys are recommended in projects where strong magnets are also used as a part of the structure.

In fact, a pulley system can cut the force necessary to lift a very heavy object in two, four, etc., depending on the designed system.  With these pulleys you can study and measure the force and distance trade off with compound machines.  These pulleys are good for science experiments as well as functional tasks.
This compound machine is an example of how these pulleys may be used. It uses three pulleys to lift a heavy weight with ease.  This particular design will reduce the lifting force from the actual weight of the object by about 30 times.  Off course, the actual design will determine the force necessary because of all the parts involved.  

If you are not lifting magnets and you will not have any strong magnet close to the pulley, we suggest pulleys with steel frames for additional strength and durability.

Pulley Lines or Pulley Strings

You will need high quality strings or ropes for your pulleys. This pulley requires a 2-mm string. Please see the available pulley lines and make sure you order the right size for your pulleys.
