YES. There are four pulleys on a garage door frame, two mounted in a stationary position on the frame above either side of the garage door frame, and two moveable pulleys attached to the springs on either side of the door.
The function of a garage door pulley is to help lift and lower the garage door by providing a point for the cables to run through and change direction, allowing for smooth and efficient movement of the door.

Yes an elevator is a movable pulley!
The garage door track's slider is attached to the door with a pair or adjustable arms, and the door is set on guide rails that use pulley wheels. Many garage doors are able to be opened with a remote control.

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.
