PULLEY BLOCKS

• These are used for experiments with fixed and removable pulleys.
• They incorporate non-deformable low-friction pulleys with cord grooves and hooks at the end of both axles for suspending from fixed support or other pulleys.
• The pulleys are 50mm in diameter, made of plastic, and are carried in tough plastic frames.
• The enclosed design of the plastic frame prevents the cord from slipping off the pulley.
• Dearing pin is easily removable and has a simple locking arrangement which prevents the pin from accidentally coming out.

They are available in different varieties:

1. Single Pulley Blocks- with one pulley
2. Double Pulley Blocks- with two pulleys
3. Triple Pulley Blocks – with three pulleys.
