3-to-1 (2-to-1) Pulleys
These pulleys cannot be used for lifting a full-body weight by a single person in the most situation. However, they work way faster than the higher-ratio pulleys. Their main use is in assisted lifting.

5-to-1 (4-to-1) Pulley
These pulleys distribute the force in a way that lifting a person is possible without assistance. However due to the ratio the speed of lifting is very low and there is substantial friction from the amount of bends in the pulley system.
