Introduction to Compound Pulley for Oil Rigs
Design and Working Principle of Compound Pulley
Compound pulleys consist of multiple fixed and movable pulleys arranged in a manner that amplifies the mechanical advantage. By distributing the load across several ropes and pulleys, compound pulleys make it easier to lift heavy objects. The design ensures that the effort required to lift the load is significantly reduced.
How does a compound pulley make work easier?
