pulleys are actually still used in elevators, cranes, and car lifts. however, they're used with motors.
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.
it helps us move things and it can be used as pulleys and things
They used ropes and other materials in Egypt to put it together.
yes car engines are pulleys
Idler pulleys are used to maximize belt contact with other pulleys and to redirect belt around other parts that might interfere with the belt.
pulleys
assuming that your question is what jobs are pulleys used for... then the answer is any job that you need to lift something that is heavy. The pulley give a mechanical advantage when used together with other pulleys to apply more force to move the object

When two or more pulleys are used together it is called a compound pulley system.
The pulley was used by the Romans to move large pieces of equipment and to create buildings. Pulleys were also used in the creation of weapons.
The pulley formula used to calculate the mechanical advantage of a system involving pulleys is MA 2n, where MA is the mechanical advantage and n is the number of pulleys in the system.
Movable pully
Pulling gears, pulleys and such.

No, pulleys can be used to lift heavy or light objects. The mechanical advantage of pulleys allows for an easier lifting process regardless of the weight being lifted.
