Triple
Tandem Pulleys
| Triple Tandem pulley is made of 3 plastic sheaves
of different sizes assembles on a steel frame with brass axles and
rivets. The diameter of the sheaves are 50mm, 40mm and 30mm and they are
mounted in tandem format (one behind another).
Each sheave can spin freely and
independently and there are two end hooks on each pulley. |
 |
| Two, triple tandem plastic pulleys can be combined to form a triple
fixed/triple moveable block and tackle pulley system. These pulleys have
sheaves with deep V-grooves with diameters of 50, 40 and 30 mm.
Pulleys are often used as parts of compound machines. They function as helper
machines, easing the lifting power. 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.
The picture shows a block and tackle design using twisted
Nylon String (100%
Nylon) along with a weight, both of which are not included in a set.
