摘要： An automated pivoting stairway system that raises and lowers through use of a drive actuator to thereby provide access to above or below floor level areas or between an elevated area and the ground floor. The system may utilize modular sections to allow on-site assembly. The stairway may be pivoted at the top of the stairway by way of a pivot drive lever attached on either side of the top step pivot frame assembly so that access on or off the stairway may be directly off the front end of the stairway, or to either side. A separate frame member may extend from the pivot point along the side of the stairway opening to a predetermined distance. This frame member may serve as the anchor point for the base end mount of the actuator.The actuator controls the length of stroke and the amount of torque that is required to operate the stairway up and down.
