Can someone give me an example of a machine that uses a simple pulley ramp system?

I would really appreciate multiple examples :)

Examples - bicycle wheels, roller skates, doorknob. A wheel that has a rope wrapped around it. Pulleys can be used to lift heavy objects by changing the direction or amount of the force.
