4 point pulley system

This pulley system provides a 4:1 mechanical advantage. The user is required to apply a force of 25kg to raise this 100kg load, for every 4 metres of rope that the user pulls through the pulley system the load will only be raised by 1 metre. Pulley systems are used to provide us with a mechanical advantage, where the amount of input effort is multiplied to exert greater forces on a load. They are typically used for hauling and lifting loads but can also be used to apply tension within a system such as in a Tensioned Line or Tyrolean. Same image I used before for a similar question: In this case it was 'removing the roof from a tractor' -- similar can be done with 8 pulleys and 1 draw rope, giving 16x lift advantage on the rope. Use low friction pulleys and add a centered, hanging weight to the center to lower the overall center of gravity -- that way it will lift level. Tag: four point pulley system. ...

Dimensions guiding this 4 point lift system are dependent on your intended use. As they grow larger, so should the materials used to fasten the four pulleys. There are weight stipulations detailing how far they should be spaced for the best safety, and also pay attention to the weight ratings for each of the parts from the ropes, to the pulleys, to the support structures. Cut two 2-by-4's to 8 feet long, and five 2-by-4's to 3 feet 9 inches long. Using 3 inch wood screws, attach the 8 foot long pieces to the ends of the shorter support pieces. You should use two screws at each end of the shorter pieces, for a total of 20 screws. Harken Hoisters lift loads from up to 45 to 200 lb.

Block and tackle are pre-assembled. SIMPLE USE: Patented system lifts evenly regardless of weight distribution. Pulley system reduces weight by 4 times for a 4:1 mechanical advantage. A pulley is a simple machine, and you calculate its mechanical advantage by counting the number of ropes supporting the weight. The pulley load reduction is equal to the reciprocal of the mechanical advantage. The maximum practical load reduction is 1/4 because few systems have more than four ropes.

Instead of the pulley being attached to an anchor it is now attached to the load (pulley A). On one side of pulley A the rope has been attached to a fixed anchor point, the rope on the other side of pulley A has been sent back down to the ground via a redirect pulley (pulley B) where the user applies the effort to lift the load.

The user is required to apply a force of 25kg to raise this 100kg load, for every 4 metres of rope that the user pulls through the pulley system the load will only be raised by 1 metre. A compound system, on the other hand, actually reduces the amount of force required to move an object. Compound systems can get complicated. For example, you can rig a system using two pulley hubs that each have two wheels, and when looping the lifting ropes through all four wheels and the two hubs, the lifting power can be very substantial.
