The simplest machine for lifting is a class one lever. It takes human effort and multiplies it.
All other forms of lifting equipment replaces human effort with mechanical force generated by an engine of some form.
The two reasons why people use simple machines are because they make things easier to pull and lift.
You use simple machines to make work (moving things) easier.
Simple machines make tasks easier by reducing the amount of force needed to perform work. They do this by changing the direction of the applied force, distributing the force over a larger distance, or increasing the mechanical advantage. For example, a lever allows a small effort to lift a heavier load, while a pulley changes the direction of force, making it easier to lift objects. Overall, simple machines enhance efficiency and effectiveness in performing various tasks.

They help us by doing things that we can't do and make easier the things that we can do.
People use machines because they want to make their lives easier.
Machines are designed to make work faster and easier. These machines do so by taking some of the manual work off of you.
Machines were invented to make work easier.

Do you mean "change"? If you're talking about "simple machines", the usual answers are direction (eg., with a pully), speed, and force.
