Metal Pulleys
Metal pulleys are available in both educational
models for higher durability and industrial models for higher loads.
| Industrial metal pulleys are used to
lift heavy objects. Some use it to lift the bicycles, cages or even
chandeliers to the sealing.
Industrial pulleys are available as single pulley blocks and double
parallel pulley blocks.
Two single pulley blocks used to lift
an object reduce the lifting force to about half the actual weight.
Two double parallel pulley blocks used
to lift an object reduce the lifting force to about one fourth of the
actual weight.
How to install the pulleys?
The upper pulley block will be hanged
to a strong hook that is already secured on the sealing.
The lower pulley block will be attached
to the object you are lifting using hooks, chains or steel cables. |
 |
One end of the rope or string must be secured
on the sealing by another hook or the same hook that holds the upper pulley. The
rope then comes down to the lower pulley, moves up to the upper pulley. Repeat
this until all pulleys have rope. Now you can pull down the open end of the rope
and lift the object.
| Metal Pulley, Single 25mm wheel
Metal pulley, single wheel 1 inch (25mm
diameter, casted from zinc alloy and plated by nickel. Used for science
experiments in physics and mechanics. Accepts ropes of 2mm up to 6mm in
diameter. Product Code:
MP1 |
 |
Use one pair of single pulleys to reduce the
lifting force by 50%
| Metal Pulley, Double parallel
Metal pulley, double parallel wheels with
1 inch (25mm diameter each, casted from zinc alloy and plated with
nickel. Used for science experiments in physics and mechanics, as well
as industrial applications. Accepts ropes of 2mm up to 6mm in diameter.
Product Code:
MP11 |
 |
Use one pair of double parallel pulleys to
reduce the lifting force by 75%.
| Educational Metal Pulleys
Metal pulleys are very efficient, high quality and very durable
while carrying a higher cost. These
pulleys with deep V-grooves are balanced for free movement have a 50 mm
diameter. They are made of Aluminum and mounted on an aluminum frame with
steel hooks at both ends.
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.

Our educational pulley systems and individual
metal pulleys are specially produced for teaching about pulleys in physics and
mechanics education. They are not recommended for industrial applications.
| Pulley Lines or Pulley Strings
You will need high quality strings or
ropes for your pulleys. The MP1 and MP11 pulleys require 5-mm rope while
the educational pulley requires a 2-mm string. Please see the
available pulley lines and make sure you order the right size for
your pulleys. |
