Abstract
A braking system and method for an apparatus or vehicle moved along a pathway by a drive mechanism, for halting the movement of the apparatus or vehicle in the event that the drive mechanism loses power or malfunctions. A conveyance system is provided including a structure defining a pathway, an moving apparatus supported for movement along the pathway, a drive mechanism operatively connected for moving the apparatus along the pathway, a brake rail having along one edge a multiplicity of regularly spaced teeth that define gaps between successive teeth, disposed along the pathway and secured to the structure, and a brake device mounted securely to the apparatus. The brake device includes a driven rotor having a central axis of rotation and an outer cylindrical surface, and a helical thread on the outer cylindrical surface of the rotor for loosely engaging the gaps in the brake rail, the thread having a width and helical pitch whereby with successive turns of the driven rotor, the thread loosely engages successive gaps in the brake rail for movement of the rotor along the brake rail.
