ABSTRACT:
Elevators are maintained in level condition by four fixed ropes or cables passing diagonally across an elevator in angularly related opposite directions. The ropes extend from opposite corners of the elevator to fixed upper and lower ends. Moving the elevator causes equal and opposite changes in lengths of the portions of the ropes extending upward and downward from the pulleys on the elevator, keeping the elevator level.
