Patent attributes
A cable driven elevator system having an elevator platform with an integral motion system is provided using one or multiple actuators. Each actuator includes a support plate attached to the elevator platform, a planetary gearbox engaged with and driven by an electric servo motor, and a drive shaft driven by the servo motor and engaged with a one crank. Connecting rods are connected between the crank and a frame. The frame supports a passenger platform. A control system is operable with each electric servo motor of each actuator for providing a simulated motion to the passenger platform including a heaving (vertical) motion such that the vertical downward acceleration experienced by persons riding the elevator exceeds 1 g, by way of example. The motion system is also capable of directly imparting vibrations to the elevator platform of up to at least 100 Hz without additional vibration generating equipment.
