Pulley systems and individual plastic pulleys
with metal frames are used in teaching about pulleys in physics and mechanics
education. Most plastic pulleys come in a steel frame; however, we are also
offering some that have aluminum frames. Pulleys with aluminum frames are
recommended for experiments in which you may have a strong magnet in the path of
a pulley and use of steel frame pulleys are problematic.
The most common educational plastic pulleys
with steel frame are:
- Single pulley with a 50 mm (diameter) sheave.
- Double parallel pulley with a 50 mm (diameter) sheave.
- Triple parallel pulley with a 50 mm (diameter) sheave.
- Quadruple parallel pulley with a 50 mm (diameter) sheave.
- Double tandem pulley has sheaves with 50 and 40 mm diameters.
- Triple tandem pulley has sheaves with 50, 40 and 30 mm diameters.
- Replacement sheaves, pack of 5
|The second most popular educational pulleys are
plastic pulleys with aluminum frame. These pulleys are available in the same
combinations as the above steel frame pulleys, but they have different part
Most pulleys cannot be disassembled and
reconfigured. If you need a pulley block that can come apart and reassembled you
may select the blue hand made pulleys.
Hand made pulleys
Screws and nuts are used to assemble a complete
set of pulley blocks for educational applications. These pulleys have no welded
and no riveted parts. You can simply unscrew the shaft and frame and separate
all the parts for practice, education or for reconfiguration.
|The single pulley, double parallel
pulley and triple parallel pulley are made of 50-mm sheaves.
The tandem pulleys are made of 50-mm,
40-mm and 30-mm sheaves.

|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
available pulley lines and make sure you order the right size for
