Info about pulleys and their uses in common products

The pulley is a simple machine that has many complex uses. The basic purpose is to making moving or lifting things easier. The advantage is that in exchange for very little effort, difficult tasks can be completed.

There are different types of pulleys and each has its own style of application. A pulley supplier can use knowledge of the uses of types of pulleys to his business advantage. Sharing how a product can make someone's life easier is a positive selling point. The pulley types are:

1. Fixed pulleys

2. Movable pulleys

3. Combined pulleys

Applications of the pulley are all around us. From flag poles to the working parts under the cars we drive and the speeds on a bike, pulleys help make our lives easier. Their biggest asset for the common user is to create motion transfer with the least amount of effort.

Recognize pulleys applications and uses

Some uses of pulleys are obvious like the rigging on a sailboat or the lifting ability of a crane. Other applications are not so obvious, with complex moving parts hidden inside housings. Most machines use a pulley of some sort. For example, pulleys are used in vehicles to increase their power and make them run more smoothly.

Explore fixed and movable pulleys

An example of a fixed pulley is a weight machine. The pulley is in a fixed position and the load changes direction with the use of force on the other end. Instead of exerting the great amount of force to necessary to lift an object up, the fixed pulley takes much less effort to pull down in order to lift the load on the other end of the fulcrum. With a movable pulley, the pulley itself moves with the application of force. A zipline is an example of a movable pulley.
Rhonda Salzmon explains the use of pulleys in an elevator system.

Discover pulleys used in more complex machinery systems

Pulley providers sometimes need to offer solutions that involve complex systems in order to best solve a particular problem. This can mean using two or more pulleys both movable and fixed. A complex pulley system can achieve both change in direction and increase in mechanical productivity. With the addition of more pulleys, the effort to move the load is lessened.
