Why is the differential hoist used mainly for light weights?

The differential hoist is primarily designed for lifting lighter weights because it utilizes a unique mechanism that involves pulleys to multiply the force applied by the operator, making it easier to lift small loads with less effort. This mechanism allows the differential hoist to efficiently lift objects that are not overly heavy, which is ideal for operations where precision and control are necessary for handling lighter materials.

This specific design leads to the ability to lift these lighter weights at a slower, controlled rate, ensuring safety and stability during the lifting process. While it is true that it can lift heavier weights to some extent, its primary function and greatest advantage lie in its effectiveness with lighter loads. The choice of materials like steel contributes to its durability but does not inherently define its lifting capacity as being mainly for lighter weights. The complexity of the mechanism does not necessarily limit its utility to light weights; rather, it is the design that optimizes it for such loads.
