About 400 B.C. At Ancient Greece.
Pulleys and levers have been used in various forms for centuries, with evidence of their use dating back to ancient times. The precise origins are unclear, but they were likely developed independently by different ancient civilizations for tasks such as construction, transportation, and agriculture. The principles behind pulleys and levers have been refined and applied in numerous inventions since then.

People use pulleys to change the direction of a force or to lift heavy objects by distributing the load across multiple ropes. Gears are used to transmit motion and power between two shafts, control speed and torque, and to change the direction of motion. Overall, pulleys and gears help make work easier by utilizing mechanical advantage.
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.
