A bi-parting elevator door actuator apparatus operably connected to a bi-parting door assembly having 1) a door interlock and power control assembly; 2) a bi-fold door actuator assembly; and 3) an electrical control circuit. The door interlock and power control assembly includes 1) a door latch assembly connected to the bi-parting door assembly to hold in a closed position; 2) a cam roller and linkage assembly engagable with the bi-parting door assembly to open and close a first power relay assembly; and 3) a door actuated power assembly having a second power relay assembly operable to be opened on opening of the bi-parting door assembly. An elevator drive motor is denied electrical power when a) the bi-parting door assembly is in an open position; and b) the traveling elevator car assembly reaches a predetermined position for stopping. A bi-fold door actuator assembly is connected to the bi-parting door assembly and having an actuator clutch assembly to prevent damage and recycle when an obstruction is present between closing upper and lower panel assemblies of the bi-parting door assembly. A specially designed roller and roller adjustment assembly is provided to reduce friction and achieve accurate vertical alignment during opening and closing of the bi-parting door assembly.
