Abstract
An escalator system for facilitating the transport of good is disclosed. The system includes a step plate comprising a horizontal planar surface configured for supporting a passenger's weight. A pulley is located near, and coupled with, a bottom of the step plate. The system also includes a retracting platform having a horizontal planar surface coplanar with the horizontal planar surface of the step plate. The retracting platform is configured to lower into the step plate. A platform chain is connected on one end to an upper adjacent step plate and connected on another end to a bottom surface of the retracting platform. The platform chain extends around the pulley and when the upper adjacent step plate moves upward, the platform chain is pulled toward the upper adjacent step plate, and the platform chain pulls the retracting platform down such that the retracting platform lowers into the step plate.
