elevators
With the string from the movable pulley
Yes an elevator is a movable pulley!
When a fixed and movable pulley are used together, the fixed pulley is attached to a stationary object while the movable pulley is attached to the load being lifted. The combination of these pulleys allows for a mechanical advantage, making it easier to lift heavy objects by requiring less force.

The difference between a fixed pulley and a movable pulley is, the wheel of a fixed pulley does not move because the wheel is attached to a wall, ceiling, or other object. Unlike a fixed pulley, a movable pulley's wheel does move. The wheel on a movable pulley is not attached to a wall or other object. A fixed pulley changes work by changing the direction of a force. A movable pulley changes work by reducing the input force needed to lift heavy objects. A movable pulley changes the direction of the input force and reduced it. A movable pulley also increases the output force.
