the other vacant slat conveyor obeying command from the system controller the elevator power arm moving on the elevator power arm track draws the platform carrier with the car immediately in front of it into the elevator the elevator raises the car to a parking floor on reaching the floor the elevator power arm similarly moving on the elevator power arm track pushes the platform carrier with the car onto the waiting transfer module which was commanded to wait in place by the controller the transfer module moving on the transfer module track of the parking floor carries the platform carrier with the car in front of the designated slot on reaching the destination the transfer module power arm positions itself to the right place the transfer module power arm lift operates and the magnetic coupling of the transfer module power arm engages with the magnetic coupling of the platform carrier the transfer module power arm moves along the transfer module power arm track towards the allotted slot pushing the platform carrier with the car into the allotted slot the transfer module power arm after placing the car in the slot disengages the magnetic couplings and returns to its retracted position on the transfer module the slat conveyor moves forward to place the next platform carrier with the car in front of the elevator to continue the parking operations till all the remaining platform carriers with cars are cleared from the slat conveyor such receiving and parking.
