Tree trimming uses combination pulleys. Also combination pulleys are used to lift engines out of cars to work on them. Some construction sites use them in places they cannot get a crane.
This depends on their intended use.

Compound pulleys are used in a similar manner to a gearbox. You can select the ratio to suit the load and the power source. With the correct pulley combination one man can lift 10 tons from a truck onto a ship without motorised assistance.
