Roller: A standard pulley has a slot for a belt, chain or cable. A reel is a wider pulley typically used in cable methods, allowing the cable to be wound all around many instances the diameter of the reel.
Fastened pulleys are pulleys that maintain the drum at one particular position.

For case in point, when hooked up to a bucket that attracts h2o from a properly, a stationary h2o puller makes it possible for you to pull the h2o sideways, lifting the bucket in a far more hassle-free way than pulling it vertically, 1 hand at a time. The excess weight of the bucket is even now the identical, but it is easier to raise.
