Pulley Blocks
PR-44
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:
- Single Pulley Blocks- with one pulley
- Double Pulley Blocks- with two pulleys
- Triple Pulley Blocks – with three pulleys.
